"Mike Nichols - the owner, did a top notch job from the time he came over to evaluate the leaking from my 28 yr old furnace, estimate repair cost and options to replace it, to doing the actual install yesterday with his associate Rick. Extremely professional, polite, personable, thorough, extremely detailed resulting in a very, very clean install. Mary from Mike’s office is also very friendly and efficient! Highly recommend Mike and Precision Heating & Cooling!! Adding to the review I did in December 2023 after the furnace install. Today (5/23/2024)Precision Heating & Cooling installed the new air conditioner as it needed to wait for the warner weather. Once again, Mike Nichols and his assistant did a top-notch job. Completed it within the estimated time window, very clean job from the furnace to the outside AC unit. Due to Mike's obsession with ensuring any wires, pipes etc he installs are very neatly tied down, he even tied down some long hanging cable wires I was just resting on the hanging ceiling. Now all tightly, neatly secured!! Highly recommend Mike Nichols and his company."

"Terrible, technician left and I still had a leaky sink. Said that I would have to make another appt. “Bullied” me into getting a $800.00 garbage disposal two months prior to avoid pipes clogging, two months later, same clogging !!! Technician went in my basement and told me I needed a new sump pump. Cellino is trying to get as much money from me as they can, without finishing their repair work. Never again. Horrible customer service and technicians have absolutely no idea what they are doing."

"I’m reluctant to leave a negative review, but my recent experience with Cellino has left me no choice. I initially hired Cellino for a greenhouse HVAC project, based on a positive recommendation and previous great service with a furnace issue. On September 6, Chris came out to assess the job, spending significant time taking measurements and photos, and assured me they had handled similar projects. After weeks of visits and reassurances, we received a quote on September 18. Though it was higher than others, I trusted Cellino based on their professionalism. However, on October 22, over a month later and after multiple assessments, the installation team informed me that the heater they specified was actually overpowered for our greenhouse—news that should have been caught early on. This oversight led to weeks of back-and-forth exchanges, ending with us exchanging the heater for a more suitable model. This delay has cost my business thousands in lost stock due to inadequate heating."

Heating and Air Conditioning questions, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

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.

A new HVAC unit typically adds about $2,500 to $3,000 to the value of your home or about 5% to 7% of your home’s value. Since a new unit can cost up to or more than $10,000 to install, it’s up to you to decide if the upfront cost is worth the added value. Consult a local AC installer to determine next steps.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.
