Called to diagnose a non operational two zone AC The tech quickly diagnosed a bad thermostat and installed a new one Great affordable work! read more

It is very refreshing to encounter a company who deals honestly and professionally with their customers, I placed a call with Four Seasons and the tech was kind and friendly, and respectful, he resolved my issue and departed, it was money well spent. read more

I cant understand and will always maintain that there is absolutely NO reason on Earth for someone not to return a phone call. Alex, unfortunately has ZERO respect for his customers. ZERO! He made tentative plans with me to install a very expensive water heater. Very expensive! Instead of declining the job and allowing me to find someone else, he jerked me around for WEEKS. Wasting not only my time, but my wife's. Because we were waiting for Alex who was bullsh%& us about doing this job. We waited , and a date was made and that passed with Alex explaining with another bullsh%$ story. After 3 or 4 weeks of this nonsense we went with another company who with 1 phone call was on the job and completed in a matter of days. Bottom line, if you value your home and the people you hire to come and maintain it, DO NOT use this company. Just like us, they will probably treat you like a pile of $hit. Thanks for nothing Alex. Learn how to treat your customers like you care. No respect. Smh read more

Timely and always helpful! I trust their input on my HVAC issues. They are who I call! read more

Overall, I have been very pleased with 4 Seasons. I feel that they have reasonable prices, good communications, and kind and mannerly people. Alex, Lassie, and others have been great. read more

Epitome of how NOT to build your customer service strategy. Called the line, talked to the receptionist of sorts. Generally speaking, the person probably could use some empathy training. I am a new home owner running into some problems with heating on a furnace/ac that was serviced by this company less than 6 months ago. Given the summer months, the heater likely saw little activity. But heater is now not turning on and I wanted to see if their previous service inadvertently missed anything (it did say everything was working correctly, which is obviously not true now). The person I talked to was not empathetic nor collaborative to do right by their customer. Perhaps company policy, but they adamantly insist on charging essentially a show up fee + any additional cost to repair/service. When I try to compromise to apply the show up fee towards the repair. The person begin to argue how I don't know what I don't know and how If I am a brand new customer, I get it, no free consultations. But in this scenario, this is potentially inadequate services from your maintenance work less than 6months ago, why would you insist on charging your customer to fix a potential shortfall on your end? The right and flexible approach should be either waive or apply the the show up fees towards the repair or somehow meet in the middle. I have no problem paying people for work. I tried to be nice but this left a really bad after taste, I would not want to get anything serviced by these folks if post services issues are handled with a "sorry, not sorry" mentality. Tbh, $100 is nothing nowadays, this is a matter of principle. I know who I am not going to recommend. read more

As a disclaimer, I have not purchased anything from this business. This review is about their lack responsiveness following a consultation for a new installation estimate. 4 Seasons was very responsive when I first called to get an estimate for new A/C installation, and sent out a technician the very next day. The technician did his thing, and when he was done he took down my email address and said he would reach out to me with an estimate, but he never did follow up. I followed up with calls and emails for several weeks, but nobody ever answered the main business phone line, and nobody ever called or wrote me back. read more

4 Seasons was highly recommended to us and after they replaced our heating and air conditioning... it is easy to see why. They do not try to upsell, they state the facts and give an honest assessment of your options. Their customer service is impeccable. I sent a message because I had a question about my new system and the response was within a matter of minutes. I have since recommended 4 Seasons to friends and they have received the same level of fantastic service. They go above and beyond with customer service to try to ensure that you have the most efficient heat and air to make your home as comfortable and efficient as possible. If you have any heating and air conditioning needs, I can not recommend 4 Seasons highly enough. read more

Here we are, 2 1/2 years after installation, and we had a gas outage. I have been calling 4 seasons since yesterday, as they are supposed to have 24/7 service, and all I am getting is voicemail and no one is responding. We were told by PG&E that the duct work is faulty and we cannot run our furnace until someone comes out to check the duct work. I have left at least 3 messages and have not received a single response. This is not 24/7 service if no one answers or calls back. read more

The air flow in my home office has been getting worse and worse over the years. I've used 4 seasons in the past and been very satisfied. Alex came on time, wearing a mask and carrying booties in his hand which he put on in the house. He diagnosed the problem very quickly and fixed it on the spot. He checked a few other vents I had questions about and made recommendations. read more

Contacted this company to come out and take a look at the job I wanted done. They came out within a reasonable amount of time to check it out, but never sent me an estimate as promised. I left a message about a week later to follow up on it, and my message was never responded to. So I can't comment on the quality of their work or their prices, but can tell you that their customer service is severely deficient. read more

Our 15+ year old wall heater gave out. Called 4 Seasons Heating and Air. They came out and gave us an estimate to replace it that was right in line with several other places that we had gotten quotes from. One thing they didn't do is try to add to the cost by trying to convince us to tear out part of our wall, or to change out the exhaust pipe (both things other places had told us we had to do) that after some sleuthing online I realized was not necessary. They were responsive and easy to schedule with, came when they said they were going to, did the repair with no muss no fuss. The heater looks good, and works great. Would use them again. read more

Had a new unit installed about a year ago with them. Jeff was great to work with and did the job quick, but things fell apart when we tried to schedule the final inspection to get permits for the job. It's been about a year since the work was done, and I have not been able to get in touch with them to confirm a final date for the permit inspection. They've stopped returning my calls or replying to my texts. We feel misled as we intended to do the job with permits but 4 Seasons isn't seem to be following through. read more

My AC was serviced regularly by this company for years. Recently, It wasn't cooling properly and would become low on freon. They came out multiple times and were unable to resolve the issue. It ultimately froze up and led to condensation and a water leak in my hallway. That was a couple thousand dollars to fix. Ceiling cut out, multiple days of dryers, drywall, painting. Additionally, their office staff does not really seem to value customers, and it can take several days or longer to schedule and come out. I contacted another company that identified the leak and corrected the problem within days. I will not be using this company again. read more

June 2020, I had 4 seasons come out to do a few minor fixes on our system - about 9 years after they initially installed my system. It was great to know that all the main people are still at the company - Alex, Lassie and Jeff (and I am sure a few others). I spoke with Jeff about my minor issues and Lassie set up the appointment for a few days later (as I was not in a hurry). Alex came out and remembered everything about the system he himself installed 8 years, 11 months ago. He asked about our rabbit - our pet that he had not seen since he was originally here - but he remembered. He and his associate were, like before, punctual and professional. All work was quickly done to my satisfaction and off they went. It was great to know that I was able to call the same service provider from years before and that the same people I had worked with before took such great care of my AC system. read more

We had 4 Seasons Heating and Air-conditioning to check our heating system in the attic of our two story house and were very happy with their service. Several days earlier, a company called BH Bay Air Services had cleaned the vents of our washer and dryer and inspected my heating furnace. It was welcomed as we were not sure it was working efficiently as the first floor always seemed impossible to warm up. BH Bay Air cautioned us not to use the furnace as it might stop working due to the blower was full of dust and that there were no filters on the furnace. The recommended service of vacuuming inside surface of the furnace, cleaning blower components and installing electrostatic filters was $850! Since we were unable to find BH Bay Air Services on Yelp and found positive reviews for 4 Seasons. We called 4 Seasons. The 4 Seasons technician found the heating system in good working order- no cleaning necessary, no filters needed except in the upstairs hall way, and did not understand BH Bay Air's reasoning for filters in the attic. The technician reinstalled the vent grilles downstairs which had been improperly installed (levers now better able to direct the air) and now the first floor warms much quicker. I requested a new thermostat be installed. Total cost: $185 ($100 for service call/diagnosis and $85 for thermostat and installation). Thanks Yelp! read more

4 Seasons Heating & Air Conditioning - Heating & Air Conditioning/HVAC Near Me - Castro Valley, California

Very quick to answer my message. Got me an appointment within a week. William, the tech, was very quick to find the problem and get the heater fixed. This company was great! Update: the heater didn't work when we tried it the next day! I called really early in the morning and left a message and they called back almost immediately and William came back right away. He checked the heater again and figured out the issue quickly: It was such a tiny little part that was broken - I am honestly amazed that he could find it. Really happy with the customer service and professionalism of this company and their tech, William. read more

Jeff Wolf was extremely courteous and knowledgeable. He took the time to explain the issue with my HVAC system and provided options for correcting the problem at different price points. He was careful about wearing his mask in the home and he wore shoe covers so he would not soil the carpet. I would definitely call 4 Seasons again with future HVAC concerns! read more

I called two companies for my heating problem: One other company I found in Yelp, Comfy Heating, and 4 Seasons. They provided almost identical diagnostics (a bad igniter) and pricing, but I went with 4 Seasons. The other company's technician was 45 minutes late. 4 Seasons managed their technician's arrival in a way that showed respect for their customer's time: They gave me a window for the appointment but promised to call while their technician was on the way so I was not kept waiting unreasonably. Their technician did call and did arrive early in the afternoon, as expected. He looked at my system holistically and replaced my filters, which apparently needed replacement, before analyzing the problem in the attic. His demeanor was professional and inspired confidence. I authorized him to do what needed to be done on the spot. Heater is working again. If you are having heating problems for the first time, 4 Seasons would be a good company to call, and the technician Jesse Casey a good bet. read more

I'm putting these guys on speed dial! Our air conditioning conked out in the peak of a heat spell. Not knowing who to call, I checked with Yelp and called these guys on a Sunday morning and left a voicemail. I wasn't expecting to hear back until Monday but later in the day I did get a call back and was able to schedule a tentative appointment for the following day. I appreciated a call back on a Sunday and also the flexibility with scheduling an appointment that worked for my schedule. Monday morning I received a second call to confirm that they would indeed be able to come out and accommodate my schedule. I loved the friendly customer service and the follow up phone call. Monday arrived and shortly after the scheduled time someone from 4 Seasons arrived and quickly diagnosed the problem. We were back up and running in less than 30 minutes. The cost was reasonable and the service was great from both the office staff and the technician. read more

We chose 4 Seasons after getting three bids - they were actually referred to us by a friend, so we were a little partial to begin with. Out of the 3 bids, 4 Seasons was the most reasonable by far. Not only that, but they were able to help us with paperwork needed for rebates. After we got our HVAC system, our house was warm and cozy in the winter and cool and humidity-free in the summer. Probably one of the best investments we made for our little house. read more

Messing around with your HVAC with no real experience is a pretty dumb idea. I know this now of course. It was a $125 lesson I learned from Alex at 4 Seasons. 4 Seasons was one of the very few HVAC companies open on a Sunday, and Alex came over within two hours of my call. Of course it turned out to be a stupid mistake on my part; I turned off the wrong breaker and blew a fuse in my furnace (Dumbass status: Achieved); and Alex had the issue fixed in a matter of minutes. So, in short, don't mess with HVAC stuff unless you know what you're doing, and if you do it anyway and mess it up, give Alex a call. read more

We were having a problem with our heater. The fan wouldn't shut off even though the heater did. This would then cause cold air to be blown through the house. I'd called another company about the same problem the previous winter, and they told me I needed to replace a part on the main board. They replaced it, and the same problem happened again shortly thereafter. The third time it happened, I thought I'd try someone else. I called 4 Seasons, and Alex came out for the call. He determined that I simply needed to change the filter. He was correct. The heater and fan have been working properly ever since. I really appreciate that given the fact that I was upfront and disclosed what the previous company had told me was the problem when it happened before, that he could've charged me a ton. The service charge was very minimal, and Alex wouldn't take the extra money that I offered to pay for his time. Thank you Alex and 4 Seasons! We will definitely call you again! read more

Recently, my fan in the attic started making noises and I called 4 Seasons. Jesse came out one time to diagnose the problem. He said it's either the fan unit is loose or the bearings are going - however, he suggested that I replace the entire fan unit (fan + bearings) to ensure we make sure the problem goes away without taking the chance of being wrong. I agreed and he came out the next week to replace the bad parts. He was on time, nice, knowledgeable, and did a great job. I would HIGHLY recommend Jesse and 4 Seasons to anyone. -Vikas read more

For whatever reason my heater stopped working. I opened the access to the Attic and found the 4Seasons sticker on the furnace. I used the "Contact Us" feature on their website, and Jeff got back to me right away. Jose and William came out the next morning to diagonse and resolve my heater problem in under an hour! I also needed a new thermostat - I was quoted a couple of options, but I was under no pressure to purchase. Thank you Jeff, Jose and William! read more

One of the coldest winter nights so far in 2013 (burrr.......), my home furnace decides to breakdown. I called 4 Seasons first thing in the morning. Technican Jeff took my phone call, called me back on scheduling options, and showed up on the driveway before noon the same day! 4 Seasons diagnosed the problem, gave me my repair options and got the heat back on with a more than acceptable price. This is the second time I've used them (the other was some years ago with air conditioning issues) and have had my decision making validated again. read more

Alex and his team were wonderful! I set up an appointment to replace the heating pipes for my home. They were on time, professional, and gave me a very fair price. I definitely would recommend them to my family and friends. read more

These guys were fantastic! I have no heat on 1/22 around 11:30am and they were here and heater repaired before 2:30pm, then there was a little glitch with the thermostat and they were back in 5 minutes to correct it. Can't recommend them enough! read more

4 Seasons Heating & Air completely delivered on customer satisfaction, timely service, and great pricing to boot. I had an old furnace in my home that finally burnt out. After having 3 other HVAC companies come through and give me a confusing (and even contradictory) array of explanations as to what happened, Alex from 4 Seasons stopped by and not only temporarily fixed my furnace for free, but gave me better pricing on a replacement unit (which I knew I'd need) than any of the competing HVAC companies. Alex and his team came back out and ripped through my furnace replacement/installation with great care and professionalism. They had to work in an extremely small room dedicated to the furnace and water heater and were able to do so without delay, issue, or damage to my home. The new heater works great, is quitter, far, far more efficient in terms of energy usage and I couldn't be happier. A week after the furnace installation, I installed my own Nest Thermostat. Everything was compatible and worked great. But 45 days later, the furnace started suffering from some pretty strange issues: Turning on for only 60 seconds, blowing cold air, showing incorrect ambient temperature readings, etc. I called 4 Seasons again and they dispatched Ken in two hours. Ken not only isolated the problem down to the Nest, but was able to rewire the Nest itself (without any instruction from the website) and ensure that my furnace was properly connected. It turned out that the wiring configuration that the Nest website provided me was actually incorrect. Both Ken and Alex are total pro's and quite obviously are operating a business in the best interest of the customer. I cannot thank them enough for their timely and excellent service. I certainly will recommend 4 Seasons with the highest regard to my friends and colleagues. read more

I have used 4 Seasons Heating and Air to maintain the HVAC system at my business. They have been very creative and were able to work within my budget to help resolve on-going problems with my AC system. Lisa and her entire staff are very professional and takes the time to meet with me to go over all the options and really listened to my concerns. They also provide quarterly maintenance service and they are very thorough and are able to make minor adjustments that saves me money in the long run. They are also able to fit me within their schedule very quickly when I needed help ASAP. read more

Very expensive! After the city came out and already identified a switch wasn't working, they replaced a $25 igniter which took less than 30 minutes. The charge for this was $275!!! read more

Serviced central heating and a/c. Very professional and reasonable. William did a great job, will continue to use them.

As a welcome to home ownership, the old HVAC unit gave-out just as the brutal Livermore summer heat hit. Ken came out and did the initial visit. He was on time, helpful, friendly and professional. I scheduled to have my rooftop unit replaced the next week. It involved a crane and Alex and his team spent the better part of a day performing the installation. The entire team was friendly and professional, just like Ken. After the installation, Alex went and picked up a pack of new filters for me and made sure the unit was working well and that I was happy. I even received a follow-up call a few days later to make sure everything was going well. For the price, service and quality of work, I am very happy and highly recommend these guys! read more

I used this company in December when my furnace was shutting off and not resetting itself. After having the heater on for sometime it would shut off, therefore we spent a few very cold nights. My husband called this company after reviewing it's ratings and comments. The person he spoke too sounded very friendly and felt confident using this company. A few days later the technician William came to supposedly fix our issue. I told him the problem and within a minute he told me the problem was the filter. It was dirty so he removed it. The heater was running when he arrived but he thought he fixed the problem. He spent a total of 15 minutes in my home removed the filter and charged me $100. Way too much for removing a filter. That night the heater shut off again and the house was 58 degrees.. We were freezing. We called back and again William shows up looking super annoyed after my husband asked if he's the technician that previously came. Basically my husband figured out the wires weren't making connection and told the professional the problem. He told us to stick a piece of paper to hold it in place. He spent 10 minutes there doing nothing and tells my husband this visit was free... No it wasn't it cost me $100 for 2 visits under 30 minutes combined. He didn't seem to really know what he was doing. Unfortunately our heater still isn't working properly. The customer service calling in was very friendly however their technician didn't seem to be knowledgeable at all in his trade. I'm out $100 and nothing was done but had a filter removed. read more

No show, not notified, no phone call to confirm, waiting 6 days for the appointment, wasted four hours waiting at home. Nothing got done. One star is too many. read more

While we didn't end up hiring this business to install our air conditioner, I wanted to write about our experience with receiving an estimate from them. I was able to get an appointment fairly quickly for them to come out and give us an estimate. I was told over the phone that they would be at our house between 10am-12pm. 12pm hit and they were still a no show. I called and was told they were just minutes away. So, they ended up being about 7 minutes late. Not a big deal but a phone call would have been appreciated. Jeff stayed in his vehicle talking on his cell phone while the technician checked things out at our house. Eventually, Jeff joined the group but not for long. His phone rang again so he stepped outside to take the call. At the end of the visit, the technician took our email address and said he would send us the estimate that evening. Well, a week went by and nothing. I finally called and was told it was emailed...but to the wrong address. To make a long story short, we finally got the estimate and it was a tad high. I received a call from Jeff a couple of days after I got the estimate and he wanted to know where things stood. I told him the truth. His estimate was on the higher end of the previous 2 quotes we had received from other businesses. He told me he would crunch some numbers and get back to me. To this day, I have not heard one word back from him. I didn't like that Jeff took phone calls while at our house. I found it to be rude and unnecessary. Even being just a few minutes late also rubbed us the wrong way. Making a great first impression is paramount when trying to get new customers. We have since gone with Rabbioni Mechanical out of Union City. Jose arrived right on time, he ignored all phone calls while talking to us, and even gave us the estimate on the spot which was about $300 less than 4 Seasons. That's what I'm talking about! read more

Called a month ago to inquire about a quote on a air and heater replacement. Left a voicemail. Never received a call back. Called last Friday (6/14) and set up an appointment for today between 1-3. It is now 515 and no one has called or shown up. Clearly business is good and customer service is not of importance. read more

We called 4 Seasons when our heater mysteriously stopped working, right when we had the first serious cold weather the beginning of November. The gentleman who helped us, William, was on time, politely told me the motor in our sixteen-year-old system had gone out, and replaced it later in the day as promised after he picked up a new motor. He even called so I would know he was on the way. The price was unbelievably reasonable- half as much as my monthly PGE. The company could have taken advantage of my lack of knowledge about heating systems. Thank you, 4 Seasons! read more

These guys are excellent, they serviced my air conditioner and did a very professional job. They were on time and polite.

I called Alex for second opinion after a prior company looked at the furnace(Fairway plumbing,heating,&cooling) said maybe an issue with the heat exchanger. I feel robbed that Alex,4 Season, did not make a proper diagnostic for my 9 year old furnace. He had his guys took it apart in order to check the heat exchange's condition, left it unrepairable. I had 2 more companies came out told me that there're other ways to test the heat exchanger without taking the whole unit apart. I'm so stun and frustrated how these professionals had ruin my furnace beyond repair. read more
