"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."

"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."

"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."

"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!"

"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!"

"Dylan was amazing. My hvac person retired & I found Dylan when my Central air decided to act up. He explained my unit was in approaching its last days but he could attempt to repair it if I wished but I decided it was time to do a complete new heating & cooling system & he made it a easy process. No pressure & no stress. Now we’re ready for the heat wave that’s apon on us. Thank you Dylan & your team for your professionalism & great service. I highly recommend & they’re my go to for plumbing as well as I’m about to have them replace my hot water tank before it becomes an issue"

"I'm submitting this review about 2yrs late. The Guys at Green energy are great! While they had a hard time transforming my house's old oil system to gas, Jonathan never stopped taking my calls (don't take that from granted, many contractors don't care once they have your money). They worked on it for several weeks--tweaking it until it finally took. 2 winters later, it works perfectly. I'm sure other contractors could've had the same problem and not been as responsive and committed as them. I'll definitely be hiring them to convert to tank-less water heating and to install AC!"

Air Conditioning questions, answered by experts

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Yes, high-efficiency models reduce environmental impact with lower energy use.

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

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.
