"We had a phone call and he actually helped me figure out that I might need a plumber instead of HVAC repair. Mark was very courteous and so helpful! If we do end up needing to go back to him I will definitely call for them to make a visit."

"My a/c circuit breaker kept tripping upon start-up of the unit. I read the positive reviews about KN, so I requested a quote and Kevin responded with a text within an hour. He was even able to come the same day and spent 2 hours to thoroughly inspect and test the various components of the system (including the connector in my attic), and replace the hard start. Kevin was very professional and thoroughly explained how the system functions and what he was doing each step of the way, which I really appreciated. I would highly recommend Kevin for your HVAC needs!"

"This Company is top notch! They quickly responded to my urgent message in regard to no heat in the house and had the service guy arrive to the door right after completing another job. They were very professional and did the repair in no time and price quoted over the phone was exactly what was charged for the service. We will definitely call this Company again for any boiler repairs. Thank you!"

"The technician and owner showed up on time and got right to work. They cleaned all the vents in the ceilings and walls. Howard and the technician were very friendly and helpful. After they finished the a/c vents, the technician cleaned my dryer vent. My dryer is working much more efficiently now. I just had to run around with the vacuum to clean up the a small amount of dust that had fallen from the vents."

"Thank you Wise Aire for giving us a great heat repair experience! After submitting a request for boiler/heat repair, Keith called me and was very pleasant. He sent Josh their technician who was just as pleasant, knowledgeable, and addressed all of our questions. Josh did a great job, he resolved our issue efficiently and at a reasonable rate. We would recommend Wise Aire, from this first experience we find them to be honest, reliable, and they do good workð"

"TLDR: This is a great plumbing company and Harris is my current go-to trustworthy plumber. I highly recommend you give HG a call for an estimate if you need plumbing work. I really loved all the work, and I'm rather difficult to please. My experience (over last few months in 2024): HG Plumbing installed our new hot SS water storage tank, a new toilet for a 1/2 bath, and a LG steam washer and dryer (GAS) in our new laundry room. Harris also added a new dryer exhaust vent to bring us up to code, which was quite tricky due to the how the old (incorrect) vent was run, and he came up with a great customized solution for us, which none of the other three plumbers I met with suggested. 10/10 on ALL the work. Harris and his team was on time, easy to communicate with (text/phone/email--he responds to everything!), PROFESSIONAL, and cleaned up nicely after themselves. Plumbing on the North Shore feels very expensive and HG prices are actually reasonable for the area, especially considering the excellent quality of the services. Invoices are up front and clear and Harris is extremely knowledgable, personable and easy to talk to (answered all my questions and concerns--and had many). We discussed whole house water filtration and few other upgrades done the line, and Harris is an amazing resource on all things plumbing and local/code issues. For those with MCS or healthy home concerns: I have sensitivities to many home improvement odors/chemicals and Harris was very understanding and respectful of this. Even the caulk he used was low VOC and finished off gassing extremely quickly. Normally I take 3-4 estimates before committing for non-emergency/maintenance work, but from now on I'm just calling HG. Done right is everything in plumbing and much more cost effective in the long run."

Heating and Air Conditioning questions, answered by experts

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.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.
