I had requested a quote and installation of my furnace and AC with Contra Costa. They are knowledgeable, responsive, reasonable and courteous! The AC got installed within 2-3 days and it's working great so far! What else do you want from your AC tech? read more

Contra Costa HVAC finally completed the certifications necessary for the county to finalize a building permit for the work. What would have been a 5 star review had the work been completed and the building permit finalized in now 2 stars because of all the nagging and appeal to contractor licensing to resolve this. read more

These guys are horrible. We had them do the HVAC in an older home with asbestos on old ductwork. We have small children and they knew we were very concerned about the asbestos. Regardless, they: 1) Hooked up the system to old registered such that air going into the house was passing through frayed asbestos 2) Left asbestos debris in our crawl space 3) Didn't fully encapsulate the asbestos in the crawl space 4) Failed to attach the vents in the crawlspace well, so a few became detached, allowing air to flow from the crawl space into the the HVAC system 5) Left a bunch of debris in the air intake. It has been a nightmare. read more

I had a great experience with Contra Costa Heating & A/C. Scheduling was easy, and the install came out really nice. I recommend using these guys! read more

Contra Costa Heating & Air Conditioning - Heating & Air Conditioning/HVAC Near Me - Pleasanton, California

Well, we took them to small claims court. They are better in court than at your heating, so we only won about a quarter of what it cost us to fix the problems. But no problem, Contra Costa just refused to pay, and there is no enforcement for small claims court. Run! Do not use these guys. Their primary technique is playing possum. They just don't return phone calls. Or pay court orders. read more

Submitted a ticket from Costco to have my 6-7 year old HVAC looked at and I guess they refer it to Contra Costa. Well, let me tell you. Run! First off, the guy was late. Second, he BARLEY saw my place, and believe I need a new HVAC. THEN the office/lady called me asking to schedule a follow up appointment for repair. Like wtf. Even the lady on the phone was speechless after I explained my experience. I told her I do not want to talk to the tech again. Well, that tech called me and try to sell me a repair $$ and $$. Yea no. Run! read more

The rebate journey is terrible, they are part of Tech Clean Energy certified and I am eligible for a rebate, but the company is unresponsive to me or Tech Clean Energy people for the past month, still no response, and I have cc'ed their CEO email and no response. Also the installation quality is not great, we had a short circuit for the HVAC system, in the crawl space, the wire they installed has a raw part that is very close to a metal in the house foundation, when they touched each other, caused the short circuit. We choose them via Costco program, it's unprofessional service from them with our experience so far, especially no response and not helping on the rebate. read more

I replaced my gas furnace and electric AC with an electric heat pump. Contra Costa Heating sells Lennox through Costco. I got a quote from them but did not ultimately hire them. But Tony was very helpful and very knowledgeable. I just decided to go with a different manufacturer read more

I reached out to CC Heating & Air directly and I was connected with Tony. Tony and his team were very helpful in assessing my property and determining the optimal equipment needed for heating and cooling my property. There was an issue with the cooling system after installation. However, CC heating & cooling came out right away (within a week after installation) and corrected the issue. I will be recommending CC to anyone who needs heating/cooling. read more

I finally gave up trying to contact Contra Costa Heating. In July, they scheduled an appointment for August 7 to repair the line sets damaged by some birds. On the date they were supposed to be here, I received an email stating the materials had not yet arrived, and they would contact me shortly to reschedule. I noticed they have lost their BBB rating and there are some questionable awards posted on their website. According to Lennox, such awards were not given. read more

my family bought a ac unit through Costco whom referred CC to us and we are having problems with the unit and i have tried to call them to service the unit without a reply for 3 weeks all I have is an estimate which wasn't even a formal estimate just notes on a brochure Costco and Lennox have no record of the unit being sold to us read more

I have left few reviews on Yelp, and this is the first one star. I am only doing so now, because I'd like to help others avoid the frustration of dealing with CCH&AC. I highly recommend staying away! Had a new heat pump unit installed last July. I have no complaints with the installers and estimator, they were friendly and professional, left the house clean. The unit itself works well. But... FIRST AND FOREMOST, they don't answer their phone or return calls. Beginning last August. I tried to call them re: the issues outlined below. From August through the end of 2023, I called over 20 times, always left a VM message, but never received a call back. These are the issues we've encountered (so far): 1) We have a booster fan under the house, which helps better distribute heat and AC throughout our house. It is connected to the furnace. The installers were able to disconnect it, but couldn't figure out how to reconnect it. They did come out and tried again, but still couldn't figure it out. After that we were never again able to reach CCH&AC. Finally, we contacted the company that installed the booster fan and paid them to come reconnect. it. It took them less than 10 minutes and said it was very simple. 2) While this "other company" was here reconnecting the fan, they noticed that one of the hoses installed by CCH&AC had a kink and water would soon begin to back up into our unit. He simply put a 50 cent PVC elbow fitting over the hose to keep it open. The "other company" told us that they always do this to help avert a potential major repair. 3) CCH&AC never sent the inspector out after the job was completed, which leads me to believe that never even took out the permit. AND... 4) As many reviewers have mentioned, we have been unable to get our BAYREN rebate. Ironically, we chose them BECAUSE they were a company that was part of the BAYREN rebate program. On top of never receiving our rebate, we had to pay to fix their mistakes! At the end of 2023, out of frustration, I totally gave up, stopped calling and (almost) stopped letting it bother me. That is, until we really needed the booster fan to work, I did try to reach CCH&AC again. They don't even answer the phone! They don't return calls. THEY DON'T CARE. I am so upset and frustrated that I am willing to put in some time to figure out where and how to lodge impactful complaints, and hopefully get their business practices audited. This includes finding out if the permit was pulled and an inspector was requested . Although we did get the unit installed and it is working great, I still feel like I've been ripped off. I can only hope we don't have any problems going forward because they don't answer the phone, follow up or follow through. Based on our experience so far, if there is a problem, we will have to hire someone else to come out and fix it. STAY AWAY AT ALL COSTS! Seriously! read more

Found Contra Costa Heating & AC via Costco referral and rebate program. I received several bids. They are not the cheapest but I selected them based on their professionalism and Costco referral. Raj is responsive. Alex and his crew is efficient and professional installing the new furnace and AC in 1 day. I am impressed with them so far. Will post follow up review if there's any changes. read more

We've been waiting since May for a resolution. Had the initial service call, tech came out was super friendly, confirmed what I mentioned was wrong. Paid him cash (mistake), he promised we would get an estimate and never got anything back. I give it time, call back in July, spoke to a manager, he asked me to email him, and also mentioned their tech had closed the ticket before anything could done. But that he would make sure I get the help I need. I called again a couple weeks later, no answer, left a message, no call back, fast forward to last Friday, I speak to someone who said she would call me back on Monday. Monday came and went and it's Wednesday and still no call. At this point I want a refund for the service call and should have gone back to the original HVAC company who installed our Lennox unit. We saw this company was a Lennox dealer and was worth giving a try, but so far nothing has been resolved and I'm out money. read more

I rarely write reviews but I have had such an incredibly difficult time with this company that I feel compelled to let others know. Contra Costa Heating and Air was contracted by Costco when I ordered my mini-split system. The initial contact and installation happened fairly quickly, although I was told to pay in FULL prior to any work being done (thought that was illegal in CA). The installation team worked very hard but kept on losing team members every day, causing the job to take much longer than anticipated. I'm only giving a 2nd star due to the hard work of the remaining installers. Getting a permit for my home took just shy of 11 months! I called Contra Costa countless times and almost never got a call back...their communication skills are beyond lacking. That permit was required before any rebates could be applied for. Contra Costa told me that they would handle everything around the rebates and that I would have to do nothing. They took pictures and told me they'd get back (which NEVER happened). They then started to tell me that it wasn't their job to help with the rebates, despite every single person I spoke to saying that they guaranteed they would take care of it. Around the 10-month mark, they even asked me to fill out some basic rebate paperwork and back date it for them....and STILL nothing happened. Now I've got a different person telling me that it's not even their job to help with the rebate despite this being a "professional" installation. Of course, this person he said he'd take a look and get back. They have been dodging my calls ever since (14 months total and growing). Not only do I find their conduct to be entirely unprofessional (I mean how are you still in business?), but I also blame Costco for using them in the first place. Complaints to Costco did not seem to move the needle either. The rebates that I would've been able to apply for a year ago have long since expired so I am now trying to see what I can do on my own, no thanks to Contra Costa Heating. This entire experience is, without a doubt, the absolute worst that I have ever had with any company. But I blame that entirely on the office staff & management...the actual service techs at least know what they are doing. But even they admit that they get almost no information about a job from the office before they get there. But that's just my experience. Feel free to roll the dice if you don't care about getting a permit or rebates in a timely manner without having to call incessantly. read more

Like others, I found Contra Costa Heating & Air through Costco. They were responsive and Tommy came to the house with a clearly very experienced member of the team. Their bid was not the most expensive I got but with the Costco rebate, it was in line. We needed a new furnace and were adding A/C. Installation took 2 days and was smooth. 5 months in, and both A/C and heat seem to be working find. Here's where things get weird. When they were done, they said they'd submit for the permits and then I'd get a call from the city to do inspections. Never happened. I've emailed, submitted the contact form on their website, and called the office several times. When I call, I always get that the person to speak with "isn't available right now." And they never call back. At this point, I can only assume that something fishy is going on with the company and that they don't want the inspection to happen. It puts us in a very awkward position as well, as it seems clear that if anything came up in an inspection, they'd be impossible to get a hold of. read more

Found this company through Costco program. Chose to work it for my furnace replacement after comparing with a few other companies, and very glad I did. Manny came out to my house one day after my inquiry to give an free estimate. He was professional, polite, very considerate to my budget situations, provided multiple options for my project, and worked out one that for me. Jaro came out two days later to install a new furnace and did a fantastic job! The work through Costco program was also effortless. I am very happy with the experience working with this company. read more

Even though this company has some partnership with Costco, they are very poor in returning calls and getting the work done. Their quotes are very elusive. They DO NOT give you break down cost of equipment like furnace, ac unit, thermostat, city permit and HERS testing etc. Not to mention about taxes. Anthony is the manager and isn't very courteous & helpful either. The installation team mismatched filter sizes and broke 2 air deflectors. I had to make several calls to have them deliver the suitable filter and air deflectors for the registers. We installed S40 Thermostat which is not connecting with Alexandar, Google or Apple Home! Lenox says they are working on it for quite some time but would not give any time frame. We reported the matter to Costco and awaiting their response. I want to return the S40 Thermostat. Anthony had the audacity to tell me that no equipment can be returned even if some of the functions aren't working! Don't hire this company ever. read more

We recently used Contra Costa Heating & Air Conditioning to supply and install our new HVAC system. The Salesman, Tony, and the installation crew, Noel, Luis, and Isaiah were wonderful. They were very knowledgeable about the product. They also dealt with unexpected construction issues on our house and were informative about the issues. In addition, they cleaned up the site well after they were finished and maintained compatibility during the process. They really seemed to enjoy the work they did. We heartily recommend this company. read more

Amazing job, wonderful service. Reasonable price. Very promising. Left the place very clean. Did their proof work before they left. I would definitely recommend them. read more

Had a plumbing pipe burst at my house and the damage included some ducting that got wet. Had the insurance company send out a contractor that gave a bid and did an exhaustive workup of my entire system as part of the insurance company requirements. System is only about 10 -12 years old and functionally working great. Their bid was really high so I asked the insurance company to send me the money and ill get it done. Had CC heating and air do he work in january ( i think it was ) and now that i need my air conditioner in july (its 120 degrees) its broke. Doesn't work no refrigerant in the line. HUMMMM I wonder what happened. Accident? This company was fantastic while it was under the ownership of the Fowlers. CC Heating and air installed this system that's why I called them. The tech didn't do what they agreed to and had to have them back a second time Don't waste you money folks! read more

Company is not great at communicating. Instead of just telling me they couldn't get the parts for my furnace the rep used up 4 months of my time saying they would "check back with their supplier" each time I called. Eventually they stopped returning my calls entirely. I also called the furnace manufacturer and it turns out they did in fact have the parts, so I have no idea why these guys had so much trouble getting the equipment through their supplier. I switched to another contractor and they were able to get the parts within a week. Wouldn't recommend these folks based off my experience. read more

If you're considering working with this team - I recommend them 100%. We'll be hiring them the next time we move. My wife and I live in SF and needed central air conditioning installed + a new heating system. We found the Contra Costa team through Costco and I'm so glad we did. My wife & I don't sleep well when it gets too warm/cold, and got central AC + heating to help us sleep better at night. Already after a few weeks both AC and heating are working great. Alex, Vic & their team worked hard over 2 days at our house. They were extremely professional, listened to our concerns, and then worked hard. On the 2nd day, Alex & Vic helped connect everything to our existing Nest system, and showed us how to maintain our system over time. Once everything was finished, their team also did an excellent job cleaning/vacuuming our house so you could barely tell they were there. Our system is still working great - and we're now sleeping great at night! read more

Sales rep was very knowledgeable. Plenty of communication prior to the install, including a site visit to confirm placement and details and confirmation calls leading up to the install date. Install crew led by Alex were all extremely courteous and friendly. They left the install location cleaner than they found it. Everythings seems to be working like it should. read more

The gentlemen that came and installed our new heating and air conditioner did an awesome job! I want to thank Alex, Edwin, Hayden, and Jairo for their hard work. These guys were professional, thorough, and clean! I would definitely recommend their services. Tommy, their Field Manager, whom we signed the contract with, also did a phenomenal job walking my wife and I through the process. We originally found out about them through Costco, so if they have services through them, we automatically knew that they must be a trustworthy company. Since we've had our system installed, we've been very happy and they completed the job just in time for winter! Our home seems to stay much warmer so come Summer, we hope to have our home stay just as cool. Kudos to Contra Costa Heating and Air Conditioning! read more

[The owner made some comments, I don't know how to reply on yelp so I'm adding more details to the end of this review] This company is so incompetent and unprofessional. Had them installed hvac because we purchased the unit from Costco and they work with Costco. Installation quality very bad. Hard to find live person to talk to. A simple work lasted for half a year... I really don't understand how they can survive, not enough competition? [Adding Details]: tl;dr, every single detail showed their unprofessional, installations, processes. I lost $1000 rebate money from PCE, and tons of energies. 1. Pre Installation: I paid mid 2023, but delayed until sept. to install, obviously they don't have anything in stock but try to get equipments after an order is placed. 2. Installation: Installed, the next hour I found cooling didn't work, had to get the contractor back to fix; The next week we found lots of details violating code and required fix: service valve not having cap or child lock; external unit not fixed to ground, duct pipe not insulated. Had to make tens of phone calls and emails to get them come to fix. 3. PCE and BREN Rebate: This is the worst part of all. They promised to file rebate out by 10/31/23 because after that the PCE rebate will be $1000 less. I again had to make tens of phone calls and emails to push them, on 10/31/23 I was finally able to talk to a lady named Julie and she told me the rebate was submitted. However she LIED! After a few months I still didn't hear anything about rebate so I then had to make another tens of phone calls and emails simply to check the rebate status and whether they really submitted the rebate, I couldn't even get this information! I had to directly check with PCE and they confirmed no rebate was submitted for me! So another tens of phone calls and emails, and it seemed Contra Costa was re-doing the rebate for me, they ordered inspections and took some pictures again. Another tens of phone calls and they told me the rebate "should be" submitted. And that's NOT TRUE again! After ~ a month I confirmed directly with PCE and they told me NO REBATE was submitted for me! I gave up and then looked into filing the rebate myself. Guess what, it only took me one hour to collect all information and fill in some online forms, the rebate is approved now. However since I missed the 10/31/23 deadline, I get $1000 less. Also I cannot have the BREN rebate because I cannot file that myself and Contra Costa wouldn't do that for me. read more

We found Contra Costa Heating through Home Depot's services hub. We ordered the HVAC tune up special and found it incredibly easy to schedule. Carla called us to schedule but we were able to text her back and schedule via text message. She confirmed the appointment and remained attentive to our questions leading up to the service date. The morning of the appointment she reached out to confirm. Victor was sent to our home to perform the tune up and he called in advance to give us a 30 minute heads-up that he was on his way. Victor arrived on time, rang the bell once, and politely waited outside while we put our pets away so they wouldn't run outside. He introduced himself, remained professional and positive and performed a thorough inspection of our HVAC system and answered all of our questions. We had scheduled an HVAC tune up with a different company before and found the other company to be aggressive and pushy so we were preparing ourselves for that type of interaction but were pleasantly surprised at how positive and frictionless our interaction with Karla and Vicore were. We will definitely call on them again for future service! read more

This company Installed a Daikon heat pump and it stopped working after one year. Contra Costa heating never returns calls to repair the leak that they found. They said they would replace the broken condenser but they have no intention of fixing the problem. We would not recommend this company or Daikon. We have spoken to both the manager and the sales guy but after many months we have still not heard from them. We also called Daikon and they only replace parts and so their warranty is useless and so we would recommend Daikon either. read more

Do not work with this company. They have quoted me one price and switched up the pricing hours after quoting. I agreed to let them requote for a "lower price" because they had messed up. They didn't "requote" a fair price but took off services included from the quote and tried to trick me into signing. They are prime example of sleazy contractors who make living off of scamming people. I do not know why HomeDepot and Costco works with them. read more

My pregnant wife and I needed a new AC system ASAP when we found out our pre-historic unit ranked on is. We live in Concord and hot days were ahead so a last minute appointment request was mad and Anthony took us in no question. He and his guys are very professional and do an AMAZING JOB! Had the job done in 6 hours or less and now we are prepared for any hot day Mother Nature throws at us. I will always recommend CCHAC to anybody that asks me. Thank you guys so much Anthony! read more

I had 6 different companies giving me quotes to replace my broken air conditioner. Contra Costa Healing and Air Conditioner did give me the best quote and they did a great job getting my permit and doing the job right. They are very knowledgable and professional and very kind. Great staff and great company to work with. read more

Contra Costa was excellent to work with. Tony and Raji were very helpful during the quote process and were readily available to answer any questions we had about the different proposal options. Once we decided which option worked best for us Contra Costa took care of the permit and coordinated with Synergy for some asbestos removal. It took about a month for the heater and AC to arrive (thanks Covid); but once everything was ready to go it went smoothly! Alex and his team of installers were very professional. They wore masks at all times and booties when they needed to enter our home. Alex answer all our questions during and after installation. I would highly recommend Contra Costa. read more

Whether you are a homeowner, residential apartment building owner and/or commercial building owner, I have found that a sound, responsible and sustainable measure to take is regularly inspecting, maintaining and upgrading the HVAC systems. This company is far and away the most professional, reasonably priced and highest quality company in the Bay Area. The company saves owner's money - a no brainer. Punctual, professional and their integrity is outstanding. Note: this is an uncompensated testimonial and endorsement of Contra Costa Heating & AC. read more

Manny and his crew were great. They were efficient and explained how to use the system.

The Contra Costa HVAC team consisting of Manny, Diego and Luis arrived promptly to start the HVAC installation at our home. They followed the required COVID-19 protocol. The team was very professional, skilled as well as very courteous. Manny was the lead technician and each member carried on the the HVAC installation in their areas of expertise. Manny answered all our questions and explained the overall installation process. They were all very focused and successfully completed the installation in two days. Manny tested the system to ensure the AC and the installed furnace performed as expected. We highly recommend Manny and his team for an excellent work they do. In our opinion, Manny, Diego and Luis are a valuable asset for Contra Costs HVAC company and they should reward the team for a great work they preform. We wish all three team members every success in their future endevors. read more

The field supervisor that came for the assessment was unprofessional and did not follow COVID guidelines. He was not wearing a mask or gloves or using hand sanitizer and insisted on sitting down inside our home to do quote calculations on his notepad--during a pandemic. He refused to email us the numbers later, which is what the other HVAC companies did. Overall very unprofessional and disrespectful of how clients may feel about safety during COVID, and on top of that, his quote was much higher than the other quotes we received. We will not be proceeding with this company purely because of this poor experience. Very disappointing. read more

Peter Rangel did excellent job root-causing and fixing our air conditioning at reasonable cost. He explained what the issue was, what caused it and made sure fix was working before he left. read more

I was pleasantly surprised with the service Contra Costa Heating & Air Conditioning provided. The staff was professional, knowledgable, and friendly. The installation was pretty seamless other than a small issue that had to be repaired the next day. When we notified them about the issue, they sent someone out the following day. All the technicians showed up with masks and followed the safety guidelines, which is very important to me and my family during this pandemic. We have a decent size house and the installation took them less than a day. I would definitely recommend them! read more

Just starting up the AC yesterday for the season revealed that there wasn't any cold air coming from the Lennox system. Called last night and left a message after hours. The staff called me up early this morning and Peter came over as promised just about an hour ago. System still under warranty and they stand by their work. Heating this past winter has been working well. The system wasn't turning on the compressor so he installed for no charge additional starter capacitor and it works great now! So nice to have cool air for working from home. Thanks again CCHAC! Highly recommended. read more

Agree with another reviewer, this place is only out to sell to you and not to provide a longer term solution. This place installed the current heater in my home, did a poor job with the duct work (these things shouldn't intersect with the water heating duct work), and only 2 years after install (when the unit was only used for 1 year). someone needed to return to do some repair work. Recently the system was showing faulty signs again and instead of offering some level of consultation they immediately went into scheduling a service provider. If you are the original installer and the product hasn't been working correctly, perhaps there's some customer service attention that needs to be addressed. I ended up speaking to Izmirian Heating and was informed 1) Contra Costa Heating doesn't know how to install the units sold via Costco and customers end up contacting them for help, and 2) Someone at this company ended up giving me a diagnostics walk through and I was able to solve the issue without needing to schedule/pay for a technician. In addition - I just learned that the work that was done in 2019 is suppose be rare. In 2019 I was told by the technician that it's a faulty switch and they always see this as the first item that fails and they need to keep returning to fix. Sure enough that switch isn't working properly again. Just got a second opinion from another repair company and it seems it's the wiring that's causing the switch to not work. Therefore, when this unit was being installed, the wiring was not connected properly. Faulty workmanship or intentional "maintenance" creation? $99 for a service call and additional $250+ for parts/labor which is only backed for 1 month after repair. Don't do business with this company. They just use their customers. read more
