"It was quite a surprise to find black mold growing in our mini-split heat-pump/ac units over the weekend! The situation was quite dire with the system emitting a bad smell and the fact that I have asthma and mold allergies which posed a serious health risk! After being told by the company that originally installed the system, “We don’t provide deep cleaning service for these units, try looking on Angie’s List (boo on Sila!)” I landed here. While other companies did respond to my bid, Atlantic Heating and Air Conditioning was the most responsive and was able to send out a team on one day’s notice (the wait for other service providers was up to three weeks!). The tech team, Josh and Zack, arrived on time and called me 1/2 before arrival as promised. They were very respectful, kept a clean work space and (since we are in the middle of a pandemic) wore masks and were very careful about the usual COVID protocols. The four units in our home are now SPARKLING CLEAN! We are 110% pleased with this job!! We will hire Atlantic as need be in the future for our heating and cooling needs. I have given up on the company that originally installed the units and will post a truthful review about them in an appropriate space online. I would definitely recommend Atlantic to family and friends. (photos attached to this review show one of the units before cleaning - did not think to take after pictures. Suffice it to say, no more mold:)"

"Great service for dryer vent cleaning at very competitive price compared to other quotes I've received, and more important, it was a fixed price where I wasn't worried about the total blowing up. Cleaning itself was quick, professional, and documented with before & after photos so that I had full confidence the job was done well. Absolutely plan to use this company again the next time I need this service."

"SumZero did a great job from the initial proposal to the final 3rd day of the installation. Everything went smoothly just as planned. There were no surprises. The installation team was very professional & courteous. Work space was vacuumed at the end of each day. Would highly recommend this company."

"Our Burnham boiler has been giving us issues this winter after just purchasing the new house over the summer. We've come home a number of times to no heat and a cold house, but had luckily managed to YouTube our way into figuring out fixes. This time unfortunately we couldn't figure it out and needed to search for an HVAC contractor. Green Energy was the first company I could even get to answer my call. At 9am Melissa was able to set me up with a day of appointment, Terry was at our house by 1pm. Since this boiler type is still new to us, Terry was great with explaining the workings of the equipment, and just some general tips for upkeep. It ended up being a simple fix with a loose relay, however I would of never been able to figure that out on my own. Terry ended up also doing a general servicing and cleaning of the unit, which they recommend annually to help the equipment last longer (we're positive the previous owners never did it). I would highly recommend Terry, he was knowledgeable and overall good guy. We also plan to sign up for their annual membership program and use Green Energy moving forward."

Air Conditioning questions, answered by experts

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.
