"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

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.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.
