"Everything from the information about the furnace and heat pump to installation was done in a professional manner. The installers were prompt and courteous. Before they left they explained how take care of the filters and the thermostat. It was not the cheapest bid but I have been dealing with this company for many years and felt comfortable going with them. I would recommend them to anyone who needs a new furnace or heat pump."

"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"Ron, the owner was fantastic, punctual, friendly, and helpful! Before we moved in, we wanted to get our air ducts cleaned. Ron answered all of my questions on the phone and was very helpful in explaining the work he would do and was very straightforward with pricing. Ron charged a flat rate that also included dryer vent cleaning and a sanitizing treatment. We didn't plan on getting our dryer vents cleaned but after seeing how much gunk he pulled out, we were so grateful he did it! It probably saved us from a fire. He showed up early, worked very quickly and was gave us some really valuable tips on how to clean out our furnace and do annual maintenance to upkeep our system better. Highly recommend. Thank you!!"

"Air ducts needed cleaning after heat pump installed. One duct was discovered to be not working at all due to improper installation. Bob agreed to come back, without extra charge, after HVAC specialists corrected duct work. Bob was prompt, very courteous and respectful of our home and yard. So glad to have had this done and would definitely hire Air Flow Pro again!"

Heating and Air Conditioning FAQs, answered by experts

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
