Mini Split Installation in Tempe, AZ

Ductless mini split installation for Tempe additions, garages, converted rooms and older homes without good ductwork.

When Ducts Are Not the Answer

Many Tempe homes date from the 1950s and 1960s, and plenty have been added onto since: a converted garage, an Arizona room, a back casita. Extending old ductwork to reach those spaces rarely works well. Ductless mini split installation in Tempe is often the cleaner way to cool and heat a room the main system cannot reach.

Good Uses for a Mini Split

Garage conversions and home offices.
Additions and Arizona rooms that run hot.
Older homes with evaporative coolers where ducted AC would mean major work.
Rental units or casitas that need their own control.

How We Plan It

Measure the room’s cooling load, including windows, sun exposure and insulation.
Choose a single-zone or multi-zone system and agree where the indoor heads go.
Plan a short, neat line-set route and a condensate drain.
Check the electrical circuit and permit the work through the City of Tempe Permit Center.

Heating Too

Most mini splits are heat pumps, so the same system heats the room on winter mornings.

Single-Zone or Multi-Zone

A single-zone system pairs one outdoor unit with one indoor head, the right choice for one room. A multi-zone system runs several indoor heads from one outdoor unit, so each room has its own temperature. It costs more, but it avoids a row of outdoor units along the side of the house.

Upkeep

Rinse the washable filters in each indoor head about once a month during heavy use. Keep the outdoor unit clear of debris. Book a yearly service to clean the indoor coil and blower wheel, which collect dust over time.

Common Questions

Can a mini split cool a whole house?

A multi-zone system can, but for most whole-house needs a ducted system is still the better value. We tell you which fits.

How long does installation take?

A single-zone install is usually done in a day.

I can’t believe it might be true— could I have found an HVAC company that is responsive, fair-priced, AND highly competent? Based upon my experience with Adams Refrigeration so far, I feel this might actually be the case! I am even somewhat hesitant to post this review, for fear that they will get too busy— finding Adams feels a bit like winning the lottery. Ultimately, though, it seems better to highlight companies that are doing things right, when there are so many others that are not. Adams Refrigeration is highly recommended.

I had my AC Blower Motor not working so air was not circulating inside the home. I had another company/technician do the diagnostic and was charging way too much for the repair(only labor charges). I reached out to Adam's as they are Authorized dealer for Carrier(my HVAC unit manufacturer). They were able to schedule the appointment quickly and also gave a courtesy call letting me know when the technician will arrive. The technician came with the part(as I already explained the issue to them), ran a quick diagnostic to ensure it was same problem and was done within an hour. Very reasonable priced(I compared quotes from multiple companies) and also took care of the issue.
