Since we had great service on our old system from Queirolo's, we called them first to install a new heating and air system. Their team is so accommodating and their work is superior in every way. We highly recommend them for every heating and air conditioning need. Call them. You'll be glad you did! Sharon Hawkins read more

Always quick to respond and find & fix issue! Maintenance always complete!! Friendly & helpful staff!' read more

After getting burned by a different, slick company I'd hired to install the new thermostats I'd purchased - who told me I needed a new system for $26K and also did NOT install the new thermostats (so I'd paid $99K for a scam estimate) - I was SO RELIEVED to find these guys. They were fast, professional, very friendly, down-to-earth people, and the price was very reasonable. If I EVER need any HVAC service again, I will hire them: salt-of-the-earth people. Words can't express how glad I am to have found them. read more

I've used this company multiple times and always in an emergency, and the service has been fantastic! They always take care of any cooling problems incredible speedily and effectively. They are reasonably priced, timely and amazing! I will use them exclusively. read more

I called Queirolos to schedule an annual inspection on the HVAC units for 4 properties. They called the tenants and scheduled the dates and took care of all of it. I already knew beforehand that one of the properties would be more than just a normal service call as the tenant said there was no cold air blowing. The HVAC technician called me to explain the work that was needed and gave me an estimate. I authorized the work and once it was completed the next day, and it ended up about $40 less than originally expected. It's nice to work with an honest company. Will definitely call them again for all future HVAC needs. read more

I have an older air conditioner that just stopped running in Father's Day. Called them and they came out replaced the control board and totally took apart the unit and cleaned every piece, checked outside fan for freon washed and cleaned it as well, replaced the filter on main unit and now it runs like a top. The young man did a great job, was detailed and thorough and showed great respect all for a great price. I highly recommend them. They are one of the few honest and decent companies left around. read more

Queirolo's - I'm a real person - Heating & Air Conditioning/HVAC Near Me - Stockton, California

Ac is working again. Queirolo's Heating and Air did a great job. Just a minor part malfunction and miscommunication on my end. 5 star service. read more

Not only is the service provided by this company good, they are more than a simple business looking to fleece its customers. When our family was amidst devastating health care cost, Queirolos started their work before payment. They arrived at our home during a terrible heatwave in the summer of 2018 to fix the air conditioning to help my family member that was going through chemotherapy to have a much more comfortable fight. All I can remember is that anything that needed to be done, modified, scheduled tweaked, Queirolo's Heating handled it professionally with kindness, compassion, empathy and decorum. They operate like a business but their is also a sense of community as they seem to generally care about the community they serve. I could not begin to share the things that went on in our home. Stacey always made sure that the proper communication took place and always made sure that everything was done right and that the person that was sick in our home was comfortable during a difficult home hospice. I could never give enough praise or enough gratitude. These people were literally like guardian angels. It was and still is very clear that they run a successful business because of their policies, but I think that they will endure longer than most and hopefully build a larger clients list because they have the merits and fellowship of extended family, not simple profit seekers. I give them the highest recommendation possible and hope that you give them a try and see for yourself. Thank you Queirolo's Heating & Air! read more

Our two year old heating and air conditioning unit was not heating at all. We called Queirolo's and they were able to come out it the next day. The part was covered under warranty and they only charged us for labor. Great communication and a perfectly itemized bill. We will be using them again. read more

Can not say enough about the quality of work and the professionalism with Queirolo's. Being a small business owner I really wanted someone I could trust and be honest with. Thank you for always taking great care of not only the HVAC but our walk in cooler and other equipment. read more

Queirolo's is a company you can trust. They know their stuff, they are thorough and honest, and today Tony went above and beyond by coming at 5:47am (!!!) to fit us in around his already tight schedule to fix my mom's AC because it's supposed to hit 107 on Saturday (she's a senior). He had come yesterday to troubleshoot an issue with a brand new unit that another company installed that wasn't cooling right (never, ever use Joe Bryson Plumbing, Heat and AC!). Tony was able to determine that the other company overcharged the unit with coolant, and that there was likely moisture and air in the line (we had just had Bryson's tech come out again and they had assured us everything was fine, but we knew it wasn't). Fortunately, we found a truly qualified HVAC company (Queirolo's) to find out what really was wrong. Tony not only offered to come at 6am today to pump out the old stuff (and moisture/air), but as I said, he showed up early. Sure enough, there was moisture in the line. He ran the suction pump for a couple hours to completely vacuum out the line (while he went off on his scheduled jobs), then returned later to put in brand new coolant and check that everything was working OK. The AC now cools normally, it was cooling to 56 degrees output from the vents in the house. Quierolo's has won us as loyal customers. I felt like they do the work as if it were their own home. And I appreciate that they were willing to fit us in given the excessive heat conditions that are coming this weekend. This is service above and beyond. Next time we'll call Queirolo's, even if we have to wait until we can get on their schedule. They are professional, competent, honest and treat their customers right. read more

The owner David Queirolo is an extremely ethical person. He stands behind his work and employees. The best Heating and Air company around.

Queirolo's is a business you can trust. I contacted them and was given a date and time certain appointment to check my relatively new air conditioning unit. The initial phone contact was handled professionally with Rob. My technician Tony arrived on time (!!) and explained the issue to me as he handled the service call. As it turns out, my problem (a coolant leak) is something that is somewhat common and coolant and dye was added to aid them in spotting the source of the leak in the future. Queirolo's now has a new happy customer and I will pass this on to friends and anyone who may need a trustworthy HVAC company. read more

Queirolo's to the rescue! Has the weather been scorching hot and your A.C. decided to wait until triple digits to break? If so, these guys are for you! Fast, professional and fair prices make these superheros a total win. Its been crazy hot and my A.C. decided to blow warm air the day I was to host a big birthday party. Thankfully Queirolo's was able to squeeze me in just in time to save the day. I'll be referring them too all of my friends and family. Thanks Queirolo's! You have a customer for life. read more

The cooling was not working for the A/C in one rental property in Stockton. I was very impressed with Queirolos's for the professional service and a reasonable charge for the first time in June 2018. However two years later, the replaced capacitor failed 4 times as short as less than 3 months or about 20 months, twice this year (April and July). I was told due to power surge not the parts, any way no warranty even if failed within 3 months. Overall Queirolos's has been able to fix every time and have clear documentations, however for my case, I am quite disappointed with the same issues happened again and again. read more

Honest, professional, respectful and courteous people! I can say I am extremely happy with the service I received from Queirolo's. They did not try to sell me a brand new unit and the tech really provided me valuable information about my options. I will continue to use them moving forward and I feel like I found a company who wants to partner with me for the long haul and isn't looking to make a quick buck by up selling me a new ac/heating unit. read more

I can not say enough good things about this company!!! They truly are super helpful and attentive and they know what they are doing. From the moment of having to contact Stacy in the office to get us scheduled and on their books to when Tony arrives it is always more than satisfactory service. Tony knows the ins and outs of the units and when he explains things to you, you feel confident because he knows exactly what he is talking about. Highly recommend this company for both commercial and residential needs !!! read more

I gave this place a call 3 weeks ago to see if I could have someone come out and give me an estimate on getting a new heating/air unit put in. It was the week before Thanksgiving, so I was warned that due to the holiday it might take some time for someone to come out. I was told my info was handed off to the person who does the quotes and I would get a call to set something up. We are going on 3 weeks now and I haven't heard a peep back from them. They must not need any new business. :( Bummer, because seems like they have a lot of great feedback. read more

Have worked with this Company for many years personally and through our business...Great group of people ....very polite, very good pricing and respond fast....really appreciate your professionalism!!! read more

My air conditioner went out in the heart of the summer busy season, just before the 4th of July holiday. Other companies had no one answering phones, didn't call back for days, or couldn't offer a service appointment sooner than Queirolo's. The tech. arrived on the earliest end of the time range for our appt. and provided courteous knowledgeable service. Much like taking my car to the mechanic, the air conditioner decided to work perfectly when the serviceman was here that day! He stayed for about an hour to do routine maintenance on the unit and observe its operation. When he left he did not ask for any payment, but told us to call as soon as we experienced the problem again, or if no further problems occurred they would bill us for 1 hour of service. In the evening, after business hours, the a/c acted up again, and I left a message on Queirolo's answering machine with the information. Q's called me back at 7:45am the next morning and had the same serviceman back at my home at 8:30. He fixed the problem within an hour, even with having to go back to the shop for a part! Great service, great responsiveness, and I love the paperless payment and instantly emailed receipt! read more

I'm very pleased with my experience with Queirolo's. I own a few rental properties in Stockton, and have used various other companies - some okay, and one really big, well-known company I had a really bad experience with. I found Queirolo's on Yelp and had consistently good reviews, so gave them a try. It was hot that week and my new tenants called me to tell me the A/C wasn't working. I called and they were out really quickly to look at it and give me various options for repairs or replacement. And they also brought an in-room A/C unit for my tenants free of charge, which made them really happy. The unit was very old and several issues with the way some retrofits had been installed before...so could have been a really easy sale to just say it was all bad and needed to be replaced. They did offer that option, but also gave me a couple of creative options and a really honest evaluation of the pros/cons of saving the money versus replacing the system. I decided to replace the whole system and they were in and out, permit signed off within about two weeks total. For contrast, I had another whole system installed by another company in September of last year, and just last week finally got the permit signed off. Queirolo's system passed the Herz and city permit inspections without any issue - show's the quality of their work was not questioned at all (the other company had to go out many times before either inspection would pass). What a difference! Every single time I called, I either reached Stacy directly, or she replied to my call (or email) right away, and Dave was ultra helpful and easy to work with. Even after the sale, there was one small issue blower fan failed (random fluke issue) and they called my tenant to schedule an appointment to look at it before I even had time to let them know I'd emailed them about it...and they were out the next day and had it fixed that day. Some companies disappear after the sale, or give come-backs low priority, but Queirolo's was on top of it...if anything, more quickly than their initial responsiveness (if that's possible!). I would highly recommend using Queirolo's - I won't call anyone else at this point. read more

Tony found the problem right away and fixed it. He saved us from the 100 degree heat. Thank you Tony you are a life saver

So my sister being owner of Bellissima Boutique in stockton and Modesto we cant have our air or heat go down because we have women trying on clothes so whenever weve had issues we call David Queirolo at Queirolos Heating and air! I called him on his day off (Sunday) and before I got out of the shower monday morning I got a call from Tony who had already got up on the roof and fixed our problem! This is the 3rd time Dave has next day accommodations for us and the rates are super reasonable. Always, Always try him 1st for commercial or residential heating and air needs! They are definitely keepers in our books!!! read more

Our AC Unit Condenser fan stopped working during the past heat wave. Queirolos did every thing they could to schedule a repair, finding a service technician that could add one more service call on their way home. The tech arrived at 7pm, I am sure way after normal working hours and was able to diagnose and replace the aged and faulty electric motor that cools the condensor. The charges were very reasonable. All staff were friendly and professional. Just a honest HVAC company busting their rear-ends to keep us all comfortable. read more

Man, I had get on here and give these guys a 5 star and more if I could... Last week on Monday was the hottest day it's been this year and as my luck would have it my AC went out. I called and although they were busy these guys came out and handled the situation and did it fast. They didn't give me the run around and I felt like it was the most honest representation of a solid company as they come. My hat's off to their hard work and knowledge and having what they needed right on hand to take care of the situation right away. They have been and will be my go to company. Thank you David for getting this done for me and keeping my stress level down. A+ read more

Our air conditioning coil sprung a leak this last summer after 25 years of service. We have had Queirolo's do annual service for the last few years, but this time we needed to either change out the compressor or upgrade the entire system. Dave came out looked at our house and then offered up some options on the installation. We decided to do the Top Upgrade that Dave proposed. Installation was performed as promissed with prompt daily arrival, complete clean-up daily after the work was done for the day and completion with flawless co-ordination with the City for final inspection. A final note....our utility bill is now less than half! These guys are are the Best! read more

We were very impressed by the customer service provided by this company. They responded quickly to our request for service, arrived when they promised, and managed to resolve the heater problem that we were not able to resolve on our own. They ordered new parts and delivered and installed them as promised. Their parts prices were reasonable and they did not charge us for all of the service calls that they made trying to resolve the issue. They more than met our expectations and we would definitely request service from them again if needed. This is truly a stand up company. read more

If you are looking for professionals you can trust, this is your team. Each person they sent to my house was extremely professional and courtious. My brand new install was perfect from day one, several months in now from near the end of summer to now middle of winter; if you can say winter in California. They also made several recommendations on making my house more efficient. They even helped find other contractors for my other improvements! Thank you all, we are very happy! read more

Highly recommended. They get the job done, and understand that no one plans or expects their heat or AC to conk out. They'll do a great job, and will try to work with you financially. Great company! We've had them out for our AC and our heater. read more

This company is the best. Our A/C went out the beginning of this week, (when it was in the 100's) and it was impossible to get someone out here to check our unit. We had to get the soonest available tech and everyone was booked out a week. We found someone that came by and checked our unit and spent no more than 10 minutes looking at it and said we needed to replace the whole system. Thousands of dollars!! So I decided to call other places and get different quotes. I called Queirolo's Heating & Air Conditioning and he sent someone out that next day, and checked the unit and said it was only a shorted wire and service a/c. He accommodated us by letting us know that he'll come out to replace it sometime this week. But for now he has my a/c running and I am so grateful. This is the company to go with if you want honesty and professionalism. Thank You for your service. 5 stars read more

Great service and quick. I was glad that they fix my furnace during winter time. They even fix the thermostat that was lose off the wall.

I have been in the unfortunate position to have my AC unit breakdown and my appliance warranty company leave me high and dry after sitting out some other guys that were very shady with their work, leaving me with a fully broken down AC unit which I needed to have replaced on my own. Luckily David Queirolo and staff came out and saved the day. They are courteous and cared about doing the job right. This team is top of the line, up front, honest and fair in their pricing. They came in on time, respectful and did everything as promised. I would highly recommend using them for ALL maintenance and repair needs. read more

It doesn't get any better than this PRESTIGE company! Dave and his team are by far the best and only company we call for any of our heating and air needs. Not only are they professional in what they do but they educate and explain everything to you. When I needed help with our heater Queirolo's was there promptly to fix our problem and went above and beyond the actual problem by helping me replace my filter with a new one and even washed out my air conditioning unit, just because. Call Queirolo's Heating and Air for all your heating and air needs- you will not be disappointed. read more

Five stars for customer service. I found myself in a bind this morning with no heat, and the contractor who was supposed to come out was a no-show. So of course I went straight to yelp. I called Quirolos and spoke to Stacy - super nice and understanding. I had taken time off work this morning, so it really came down to a time-issue for me: Already lost 4 hours of work and had to go back. HOWEVER, customer service is so important to me, and I really felt comfortable with this company.....so, I will need more work done in January or February and I will go to them then. For now, I am putting on another layer of clothing! So right now they get 5 stars for great customer service and really trying to schedule me in....I will update later! read more

I first called them for my heating, GREAT JOB! My next encounter was for my air conditioner that went out over the labor day weekend it was scorching HOT I came back to Stockton from the Bay to find it was triple digits of course they were not available due to long weekend but because I had such great service before I decided to WAIT until they could fix the problem, as always they didn't disappoint GREAT SERVICE they will always get my business. read more

I have used them for years for all my heating and air-conditioning needs they have been fast responsive always honest and do a great job!

I've used Queirolo's Heating & Air a few times...once for our business and the other for my home.....and these guys are legit and do an awesome job. They are fast, reliable and honest. If you need service done, I totally recommend this Queirolo's! read more

I love, love, love these guys. Great customer service from the phone call to the bill. Family owned since forever and it shows.

If you are looking for a prompt, efficient, honest and pleasant company to repair or service your air conditioner Queirolo's is the one. From the phone receptionist to the gentleman who came to replace the capacitor on my air conditioner they are a class act. I highly recommend them. read more

Queirolo's took care of this client promptly, efficiently and the cost was quite a bit lower than the competitions quote! Thanks Queriolo's for taking care of my client! In addition, I hired Queirolo's to fix the A/C at my home. They again, had outstanding service and fair pricing! Can't say enough about Dave, Stacy and the Queirolo's team! read more
