"My Central AC unit went out; the box outside smelled like something had fried. I called NETR, and they said they would send a technican over in a week. The technician came on time and promptly inspected the unit. He reported that the capacitor had blown, and told me that he had a spare back in his van. The labor was covered by the diagnostic site visit fee, it was just the parts cost. I told him to proceed and he replaced it. My AC was back up and running within the hour."

"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"We are overall very happy with the project. Sila had to install a high velocity air conditioning system in very limited space. They provided a timely quote and showed up and did the work professionally and on time. There were a few hiccups, such as the installation of the hatch to the attic space, but Sila’s carpenter agreed to fix the problem at no additional cost to us, so I consider that to be excellent service. After two weeks, the system has been performing exactly as we hoped."

"Atlantic Heating & Air Conditioning responded professionally and quickly to my call. A service technician diagnosed the problem and ordered the a new gas valve and two sensors. A second technician, replaced the defective parts and serviced the boiler. Both technicians performed their work in a very professional manner, identified the source of the problem and clearly explained what was needed. I was impressed with their work and would definitely hire them again."

"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

Small jobs welcome

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

"Duct Kings did a fantastic job cleaning my dryer vent and air ducts. The technician showed me before and after pictures of my air vents and I was amazed how much dust and junk was in there and how clean it looked after!"

"Kilpatrick HVAC is my go to company for all things HVAC. They have replaced a few furnaces and air conditioners for me over the years. Mike and John are very good at what they do. They are a lean team which makes them very competitive compared to big HVAC companies without sacrificing on quality. I highly recommend Kilpatrick HVAC for your HVAC needs."

"Ruben cleaned my dryer vent first and did such a great job, that I had him come back and clean the air ducks/vents. Both times he called ahead of time to let me know he was coming, he is very efficient, cleaned up when he was finished and did a great job. I would recommend him and will have him come back again."

"David Sampaio from SumZero was one of six contractors we interviewed for central AC replacement. David was very helpful in our decision making process when we were deciding between AC and heat pump units. His price was very reasonable too. We chose the heat pump in the end and are very happy with the choice. David’s team was very polite and professional during installation, they did an excellent job setting everything up and cleaning the area. High five, David! Thank you!"

Air Conditioning questions, answered by experts

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

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.

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.
