"I hired Onofrio to replace my gas furnace and install a new AC unit. A few months later when I had a minor gas leak in the pipes (unrelated to their install), they came out within a few hours to fix the leak. What REALLY impressed me was how they came to bat for me when the gas company initially said that it could be as long as next day to turn my gas back on after the repair. This was during the coldest days of the winter and I was very grateful that Onofrio stayed invested in me until everything was remedied."

"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."

"This company is so responsive and helpful. They come when needed and answer all my question. I am so glad we found them. They have helped with repairs and replacement. They have found ways to do some difficult things in our quirky space. They have made things better and safer for us. Passing our inspection by the building inspector was easy because of their good work. They do all they say they will do and in the time frame set. Every worker I have met or talked to has been terrific."

"I have the Total Mechanical Systems Total Comfort plan. It is wonderful I purchased the Comfort Plan when we installed our HVAC System. This is a great service plan for a reasonable rate. You get check ups on your HVAC, electrical, and plumbing systems.,You also have access to repair services, electricians, and plumbers at a discounted rate. Great overall plan to maintain your home or condo. Recently I had my annual Furnace/HVAC check up. The technician, Marquez, was professional, knowledgeable, and pleasant. Marquez really knew his stuff and explained to me how my furnace works and what the telltale signs are that I might need repairs. Fortunately I have not needed any repairs thanks to their great maintenance plan!"

Heating and Air Conditioning questions, answered by experts

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

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

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.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.
