"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"Excellent! I love JT Dunn Heating and Cooling. We selected them out of 5 different contractors to install our brand new furnace and conditioner in 2017 and we hadn't had a problem since. We just had a 3 year tune-up and nothing was wrong and the ac is quietly humming away outside. Thanks to employee Robert Fitzgerald for coming out today and doing a awesome job and keeping us as customers!"

"My AC stopped working a few days ago and Rhymes is the third AC repair company I hired. The first company didn't have the part, the second company wants us to change the zoning system. Neither of them took the time to look at both the outside unit and the inside panel. Steve from Rhymes showed up on time, he took the time trouble shooting my zoning panel and checked each part of the system. He is very diligent and paid attention to details. He changed a part and made the system working again. We didn't have to change the whole thing. He is honest and experienced. I would hire him again."

"I’ve used this company twice. My husband has a medical condition that is affected by heat. The first time the air conditioner wasn’t working they made every effort to assess the problem immediately when I explained the medical condition. At the time they corrected the problem I was advised the system was probably 20 years old and we may have to consider a new system soon. The second time I contacted Comfortable Carla’s was about 4-6 weeks later when the system wasn’t working again. This lead to a system replacement. I was provided with different options, my questions were answered and the installation was completed as quickly as possible, especially in view of my husband’s medical issue. The staff was was professional, efficient and kept me apprised all throughout the process. I highly recommend this company."

"Bernie is incredible- no, really. I could not have asked for a better technician today. After a month of no A/C and getting the run around with our warranty company (besides the point), Bernie showed up and saved the day. He took the time to really explain the problem, the steps he took to fix it, and some helpful tips for the future. After repairing our AC unit he walked around the house upstairs and down in the basement to show me how to control the force of air coming out of the vents. He is so friendly and so great. We will definitely reach out to him again in the future if we ever have issues. Thank you Bernie."

"We were thankful for the efficiency at which the team was at determining the issue, providing and estimate, and scheduling our service. We had two workers on the day of the replacement who were punctual, courteous, and professional. Care was taken to keep our home from being damaged and the areas were cleaned prior to departure. Thank you for getting our new furnace installed before the external temperatures went into the single digits."

Air Conditioning questions, answered by experts

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.
