"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 Oil questions, answered by experts

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.
