We provide the required, but often overlooked annual deep cleaning of your Mini Split Heat Pump so you don't have to! Most owners don't realize manufacturers recommend a complete deep cleaning for these units once per year to provide healthy air, cost effective heating and cooling, and extend the life of the heating and cooling system. We deconstruct, detail hand-wash, and pressure wash your Mini Split Heat Pumps and then fully deep clean and pressure wash the interior coil system to remove mold, mildew, pollen, dander, and other allergens completely from your unit. This not only immediately and drastically improves your indoor air quality, it also immediately reduces your energy consumption and costs associated with running an uncleaned unit. We are a family-owned and operated business out of Charlestown, NH, that started by simply meeting a family need. Like most people, we thought cleaning our pull-out filters was enough. When our installer explained that our unit wasn't functioning properly because we had never deep cleaned it, we got to work and removed a staggering amount of build up from inside it. We immediately began noticing in countless local restaurants, offices, gas stations, and shops, the units on their walls and ceilings were visibly blowing around debris or dripping contaminated fluids, most likely from the same lack of proper cleaning. With five children in our home, asthma, allergies, and a dog, as soon as we learned the significance of deep cleaning and saw the difference it made, we decided to help people who are in the same situation we were. Having seen the importance of deconstructing and deep cleaning our Mini Split Heat Pump for our own family, and seeing the immediate difference it made in our air quality and utility bills, we are grateful for the opportunity to serve our community, providing a healthier, more comfortable environment for them and their families.

"He started great, but went down hill. 5 months to install a new heating system after being told it was 5-6 weeks.I was told he had no idea when he could finish because he started a 92 unit condominium project. On another project they installed an HVAC system with no control board. Lied to continuously about dates. We paid in advance for the work and found out afterward that he fired half the staff (I now know why.) Rather than be upfront about the issues he was facing we told lies. Very frustrating and found Devin to talk like an excon. Say one thing and do another with a very straight face."

Heating and Air Conditioning questions, answered by experts

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.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

An AC compressor is one of the most expensive parts to replace on an AC unit if it breaks. You’ll pay up to $2,300 if you need a new one. If your AC is blowing warm air, there doesn’t seem to be a lot of air coming out of the ducts at all, or the unit cycles on and off a lot, you may have a broken compressor. Call a pro to check out your system. 

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.
