Thornton Heating Service, Inc.

We had a Thornton crew come out to professionally clean our ducts. The crew did not communicate anything that they were doing, and I had to call to ask about some things later. To make it worse, our ducts did not pass sample testing by an independent inspector. The swab the inspector used to gather the sample came out black, and he didn’t even believe that I’d had the ducts professionally cleaned. I also contacted the company about this, and they never bothered to respond. When I first called, before I paid, the customer service was great. Good ole bait and switch here.

Incredibly professional and quality work. Nick, Justin, Drew, and the other technicians that I’ve worked with are kind, hardworking, professional, knowledgeable, and their work is top notch!

We have been using Thornton Heating and cooling for at least 11+ years for our home and our rental property. As is clear when I interact with the courteous office staff as well as the knowledgeable and friendly technicians, this business clearly values customers and takes pride in providing outstanding service. Thornton people are prompt, reliable, professional—it’s a pleasure to work with them. Highly recommended.

Thornton did just a fantastic job. I spoke repeatedly with Brian before we decided to go with them for the installation of a new air conditioning unit. They showed up exactly when they said they would and the whole day, they were professional and careful. At multiple steps along the way, they would pause or change something small just to make sure it was done exactly the right way. I cannot recommend them enough.

Thornton is a fantastic HVAC company and has been servicing my home since I moved in 3 years ago, and they have serviced it since it was built in 1997. I have an annual service plan so I never have to worry about anything going wrong because they visit quarterly and keep things in tip top shape. When something needs to be repaired or replaced they provide details, options and pricing in advance and patiently answer all of my questions. Nick, especially, goes above and beyond and his attention to my home is valued and appreciated. I highly highly highly recommend Thornton!

We first used Thornton when they installed a Generac back up generator. Nick and Mitch were so thorough, so detailed, making sure that everything was exactly to code. We have since used Thornton for all our heating, A/C and plumbing. Their technicians are so experienced, extremely knowledgeable, courteous, and they leave the house cleaner than when they arrived! We just had two new 75 gallon water heaters put in. Ricky and Mitch were here the whole day. Our faucets (stream and pressure) are working better than before the installation. The guys put in a back up alarm system in case of leaks (which happened with our old water heaters). They also reconstructed pipes so that each water heater would operate independently. Thornton's work is so detailed, so complete, and so thorough. Thornton is extremely trustworthy, and very responsive. Kim is the best in scheduling appointments and following up, making sure everything gets done, and we are extremely satisfied. I highly recommend Thornton for any heating, A/C and plumbing. Their work and customer service is outstanding.

We have used Thornton for our heating and air-conditioning needs for many years. They perform annual spring and fall regular maintenance on our systems and last year installed new furnace and air-conditioning systems, including the necessary thermostats, etc. They are professional, on time, on budget and trustworthy. We have gotten to know the people who work at Thornton and they are nice people to work with and have in the house. Would recommend Thornton to anyone.

Wonderful experience, Thornton is always professional and friendly. Every time they help us with our air conditioning and heating it is easy and fast. Today we had a very good experience and the problem was taken care of.

We have been using Thornton for over 10 years. They take care of us and our HVAC system. They’re real pros. They tell us what to do so we don’t have to call them. They value they add to their service is top notch. Highly recommended.

Thornton always does a good job.

Used their website to send a message yesterday evening and got a call 1st thing this morning and Rick arrived around 2pm, even earlier than the 3-5pm window.

Had them replace my baseboard heaters a year or so ago and today, Rick came out and installed Freon.

Highly recommend.
