Nantucket Heating and Air Conditioning Maintenance

If you live here year round, your HVAC system is a workhorse that only gets a break during a couple of months of the year. The rest of the time it’s hard at work keeping your home comfortable.

Our experts can come out at the start of each season to perform maintenance to keep your unit running smoothly.

Mini-Ductless Systems

Mini-ductless systems are a great choice for those who want a greener solution to heating and cooling that offers many advantages over a traditional system. As their name implies, these system don’t require Nantucket ventilation ducts to operate. This construction not only cuts down on the initial cost of installation, but it prevents energy loss through leaky ducts as well. Plus, these systems are flexible and can be turned on only in rooms currently in use, saving even more money. Fast installation is another benefit—your new system could be up and running in as little as a day or two!
