"Great company to work with. They're very thorough on what needs to be done to fix a problem and are very professional. So far they've done two repairs to my heating system and were always pleasant and willing to help. Keith and Ron are great guys and I'll be calling them for my HVAC needs."

"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."

"Nick called within an hour and came to my house at the end of his busy day. He was professional and explained everything as he diagnosed multiple issues with the HVAC unit. He had the system up and running before leaving. Highly recommended."

"We called during a heat wave on a holiday week when our A/C broke, so we knew it would take a while to get an appointment, especially as first-time customers. They were able to immediately schedule us for just under a week out, and let us know up top about how their services and payments, etc. work. We actually called another provider simultaneously to see if they could come earlier, but they just ended up giving us the runaround for days instead of just saying they were too busy. They confirmed a smaller time window the night before, and showed up first thing the next day. Abner was awesome, and it was such a huge relief to have someone so nice and professional, explaining everything like we didn't know anything about HVAC (because we don't). He broke down 6 options for us to move forward ranging from the minimum service fee for the cleaning all the way up to addressing everything he saw that was weighing down on the system. He explained which options we could wait on and which ones were higher priority, etc. It feels so rare to get a home service provider with this kind of professionalism these days. I wish these guys did automotive! I didn't rate them on price because I don't have a good comparison. But we will definitely be using them moving forward based on reliability, customer service, and professionalism."

"Dean and Anthony provided our HVAC and dryer duct service today. They were both courteous, honest and efficient. Dean provided quick and easy to understand additional options for service. They did a great job and we asked for them to come back again this time next year for additional service on our HVAC system."

Heating and Air Conditioning questions, answered by experts

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.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air
