Frequently Asked Questions

Ductless air conditioners are a great option for homes that either don’t require full-home air conditioning, or homes that need their larger system supplemented. For example, if you are in an older home where the ground floor stays cool but the upstairs bedrooms get hot, a ductless A/C unit may be right for you.

The best way to maintain your ductless A/C unit and extend its life is by having a licensed technician do a yearly maintenance check. This will ensure it is running properly and help to prevent the need for repair.

A ductless air conditioning unit and a single head unit can be compared at roughly the same cost. However, you should always consider what type of unit will perform most efficiently in your home.

There are a number of factors unique to your home and lifestyle that should be taken into consideration. Once you have determined which factors are most important in your air conditioning unit, educate yourself on the options available, and take the time to speak with someone such as a Home Comfort Advisor to give you information specific to your situation.
