"There were some issues when system was first installed. A lot of "pipe knocking" and radiators not heating up. This being a hundred-year-old house I could understand the problems. After speaking with their excellent customer service team, the service crew returned and resolved all issues! I plan on using Onofreo Home Comfort Systems for all my HVAC needs in the future."

"Exceedingly STELLAR work; BEYOND professional decorum elicited by the company’s OWNER AND staff MEMBERS (specifically the technicians that performed the installation). Overall, we HIGHLY recommend this company to neighbors, family, friends, coworkers & even strangers in our community that may be in need of any HVAC or others services for their homes and/or businesses. Financially, they were on par with our anticipated costs for the work we needed done. FAST, QUALITY WORK that we’d NEVER hesitate calling on again for any future needs that this EXCEPTIONAL, ‘5-star worthy’ company provides! Thank you especially to Ron, Carlos and Brandan… we truly enjoyed meeting you and the pleasure of your company while you worked diligently in our home was all ours. Perhaps this review seems “over the top”or contrived, but we truly wanted to reward this company properly with a review that sufficiently and congruently matched their “talk with the walk” behavior. As you (a co-consumer) know there are so few these days that that elicit good, old- fashioned business ethics. We want you to know this was honestly a job TRULY well done!"

"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."

"Alex was great! Courteous, responsive, prompt, friendly, but more importantly, honest. The job couldn’t be done because of the structure of my HVAC system, yet Alex (and Vinny) took the time to explain the problem and tried, albeit unsuccessfully, to seek an alternative solution. I have such respect for his honesty. I highly recommend using this company, for that reason alone."

"I highered Bruce and his team, we're very happy with the service. They installed a couple new baseboard heaters to our existing unit to add more heat to a few rooms that's were cooler than we liked. We're very happy and much warmer. Bruce and his team were responsive and open to everything they were doing. Fast and efficient highly recommended!"

"My husband and I highly recommend Jeremy. We had power issues and Jeremy walked us through everything that was going on. He went over the pricing and stuck to it. He is quick to respond to communication. We are very happy with the work he and Austin did to correct and upgrade our electric service. We will definitely be using him for future electricity needs and recommend him highly!"

Heating and Air Conditioning questions, answered by experts

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.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.
