 Trustindex verifies that the original source of the review is Google. The tech who came out to clear drip line from ac unit was great and very efficient. Would use their service again if needed.  3 text messages for this survey in a week seems a little heavy. Doing this to stop the text messages.

 Trustindex verifies that the original source of the review is Google. What a great company this is. I called at 3:00 on a Friday afternoon and they had a tech in my area who was there at 6. He quickly diagnosed the problem and got us up and running again. Very friendly and professional all around. I highly recommend and will definitely use them in the future.

Still Have Questions? Let Us Help

Is a ductless mini-split right for my home addition or garage?

Yes — additions, converted garages, attics, and sunrooms are ideal for ductless mini-splits. Because they don't require ductwork, they bring efficient heating and cooling to spaces your central system can't reach, without major construction. It's one of the most popular and cost-effective solutions for these rooms.

What's the difference between single-zone and multi-zone?

A single-zone system conditions one room or space with one indoor unit. A multi-zone system connects several indoor units to one outdoor unit, letting you control the temperature in each room independently. We'll help you choose based on how many spaces you want to cover.

Do mini-splits heat as well as cool?

Yes. Modern ductless mini-splits are heat pumps, so they both heat and cool efficiently year-round. That makes them a great single solution for spaces that need comfort in every season, without adding a separate heater or window AC.

How long does a mini-split installation take?

Most single-zone installations are completed in a day, and multi-zone systems may take a bit longer depending on the number of units. The installation is clean and far less disruptive than adding ductwork — usually just a small, tidy connection between the indoor and outdoor units.
