"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."

"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."

Heating and Air Conditioning questions, answered by experts

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.
