"My boiler went out and as always it happened on a weekend. I agreed to the extra fee for an emergency call. He was unable to fix the problem on the spot I think, due to a part unavailable on the weekend. They sent somebody back on Monday and fixed the problem while I was at work. When I got the invoice, there was no additional charge for the second visit and it ended up costing me just for the one service call. This was the first time I used Onofrio for my heating. Last April they put a new central air conditioning unit in my home. I was impressed with their attention to detail and service, so called them to handle this problem, and I will be using them for everything going forward."

"The appointment was made within 2 days of contacting them. The technician (Brian) was punctual for a 7:30 am appointment. Once there, Brian did a fantastic job of communicating the services that he was performing and kept me very informed about the status of the AC system. He found some issues that had been previously overlooked by former HVAC technicians and provided me with a very detailed understanding of what the outlook for my unit should be in the future. I noticed an immediate improvement in the cooling of the house as well as the air quality. I can't thank this company and this technician enough for being so professional in the way they conduct their business. I would recommend them to anyone in need of HVAC service."

"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."

"Went very well, considering I needed my furnance fixed on a Sunday. I was able to call up at 7am and the tech was out to my house later that morning. Juan did a great job, fixed the problem and explained to me what he did. I would hire this company and ask for Juan if you have any HVAC needs."

Heating and Air Conditioning questions, answered by experts

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

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.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.
