"Great. I was out of state and my house and dog sitter called. My house temp, was 85! Look up Angie’s list. Called the business and explained the problem. They got the repair man out the next day...on a sun day!! My air was fixed by the repair man that day. My sitter said he was very nice .....price was great,,, I would have them again. This is the 2nd time I use Angie’s list."

"The service was excellent. Adrian arrived promptly and was professional throughout the service process. We truly feel that there’s a higher level of air quality in our home following the process. I would highly recommend Mr. Duct if you’re in need of high quality air duct cleaning services. Scheduling was also extremely easy and the office was highly and promptly responsive to all of my questions."

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit.

The customer service, quality of service, the precision, knowledge and expertise made me quite confident that I found a highly reputable company to handle all of my HVAC needs. Awesome workmanship! I highly recommended their services! Re: a few of the "other" HVAC companies out there: if a HVAC company has to advertise on TV CONSTANTLY to try and draw in business, your business isn't good enough to build a solid trusting customer base . . . (those other companies can learn a thing or two from Temperature Pro!!)"

"We were having issues with our current furnace and decided to purchase new equipment versus putting repair money into an obsolete one. Due to the unreliability of the old unit, we wanted the new furnace/AC installed before we went on vacation.  They arrived on time, and completed the work in the time frame promised. All the work was done to the highest quality, and exactly as promised. This work was done on a cold day, and with over a foot of snow around the house, including around the old air conditioner. With the cold temps, we were very happy the total job was done in about 6 hours. The equipment is working extremely well. TR Miller took away all the old equipment, and did a good job of explaining the operation of the new furnace, thermostat, humidifier, and air cleaner. I would highly recommend this company for any heating and cooling work.

"Amer Talla is the best! He knows the industry, he is an expert HVAC person all-around. Actually, he is a general contractor. He diagnosed the problem, provided a detailed solution, and was the consummate professional. He is not just the expert you should call because he is knowledgeable and professional, BUT he is thorough. You can tell he loves what he does and he cares about his customers. He’s the one I will call for future maintenance and anything else HVAC-related. I highly recommend him!"
