"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

"It was scorching hot outside and our AC went out. We immediately called Petrocelli Services and they sent out a professional Technician to diagnose. It turned out we needed a new AC unit after 16 years. The staff was considerate of cost, time and made it extremely easy for me to understand the next steps. The open line of communication was amazing and kept me involved and provided me with detailed order form. Staff also played a huge roll in educating us on maintenance when caring for our new product. I will definitely call them again and refer them to my friends and family!"

"I find them to be very honest. They don't try to make you upgrade. They sell you a little contract each year. They do a clean out of your equipment and a checkout of your equipment in the spring and then again prior to the winter. I have just found them to be real down to Earth. They have told me that my unit is better built than anything that I could buy today. They said as long as I could get parts for this one they suggest that, even though it is not as energy efficient as some of the new ones, it is older, but it is built better and it will last longer. It is very hard to find anyone in that business to tell you that because they are in business to sell new systems."

"the unit installers (also who gave the estimate) were very professional, personable, and courteous. They worked quickly and efficiently, even working through a couple of supply related snags, to get the job done, as promised. They answered all questions, in plain language...no tech-speak jargon or smoke and mirrors. Job was completed satisfactorily. Highly recommend Noah and Nick!"

"Thomas was excellent about responding to our request for an HVAC system bid, and when chosen, they were able to schedule our installation within a couple of days. They asked our needs and made recommendations for the right equipment for our home. The crew was efficient, polite, and neat. I could not ask for more!"

Heating and Air Conditioning FAQs, answered by experts

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

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.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.
