"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"We had a great experience working with Dylan! He was professional and delightful to work with. He had a cancellation the day before our job and reached out to schedule with us within 24 hours of getting an estimate. We would definitely use him again for HVAC and now we know he’s also a licensed plumber, he will be our first choice!"

"Atlantic Heating & Air Conditioning responded professionally and quickly to my call. A service technician diagnosed the problem and ordered the a new gas valve and two sensors. A second technician, replaced the defective parts and serviced the boiler. Both technicians performed their work in a very professional manner, identified the source of the problem and clearly explained what was needed. I was impressed with their work and would definitely hire them again."

"My electrician from Cotti-Johnson HVAC was a master electrician. If you get him, you are getting the best. I went with the most expensive work package of the 3 that were presented. First off, it was pricey. I knew that going in. I want Cotti-Johnson to understand that I am serious about a working relationship with them. I feel I have done that with their electrical department. Now, if I need their plumbing or HVAC service, our relationship can build off the first experience."

"Bob did a new mini split install for me and I couldn't be happier with the work. He was professional, timely, and had excellent communication. He was also very knowledgeable and made some great recommendations for the project. I'd recommend him to anyone looking for HVAC work."

Heating and Air Conditioning questions, answered by experts

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.
