"I whole heartedly recommend Airco. Their team was experienced, skillful, friendly and professional throughout the duration of this job, from Joe's first visit to my home to discuss air conditioning options to Derek and Cam's final touches on the duct system. I had complete confidence in them, as well as in Steve, Danny, Frank and Patrick. Additionally, Airco's connections to MassSave and Commerce Bank meant financing and payment options to suit my budget. No more hauling loud and heavy window a.c. units up from the basement. Instead, I am enjoying consistent cooling throughout my home with no noise whatsoever. I am a very happy customer!"

"Excellent. I've had Genove install both gas and oil heating systems in my properties, most recently oil. They have also installed central air/hydro air and handle my oil delivery. The techs have always been polite & knowledgable. Their customer service is impeccable. As a landlord/home owner, I couldn't be happier with them handling all my HVAC needs and would recommend them to anyone."

"We are overall very happy with the project. Sila had to install a high velocity air conditioning system in very limited space. They provided a timely quote and showed up and did the work professionally and on time. There were a few hiccups, such as the installation of the hatch to the attic space, but Sila’s carpenter agreed to fix the problem at no additional cost to us, so I consider that to be excellent service. After two weeks, the system has been performing exactly as we hoped."

"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:)"

"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

Small jobs welcome

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

"Duct Kings did a fantastic job cleaning my dryer vent and air ducts. The technician showed me before and after pictures of my air vents and I was amazed how much dust and junk was in there and how clean it looked after!"

"Dylan was amazing. My hvac person retired & I found Dylan when my Central air decided to act up. He explained my unit was in approaching its last days but he could attempt to repair it if I wished but I decided it was time to do a complete new heating & cooling system & he made it a easy process. No pressure & no stress. Now we’re ready for the heat wave that’s apon on us. Thank you Dylan & your team for your professionalism & great service. I highly recommend & they’re my go to for plumbing as well as I’m about to have them replace my hot water tank before it becomes an issue"

"David Sampaio from SumZero was one of six contractors we interviewed for central AC replacement. David was very helpful in our decision making process when we were deciding between AC and heat pump units. His price was very reasonable too. We chose the heat pump in the end and are very happy with the choice. David’s team was very polite and professional during installation, they did an excellent job setting everything up and cleaning the area. High five, David! Thank you!"

"We got quotes from 2 other companies for installing a mini-split AC/HeatPump. Green Energy was the least expensive, but we also hired them because they seemed to know a lot about mini-splits. The install was done very professionally, and the mini-split worked even better than we expected. We just had a one year service, which was also done on time and professionally."

Air Conditioning questions, answered by experts

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
