AC installation in Washington, UT
A new air conditioner in Washington and St. George typically costs about $5,000 to $8,000 installed for common 2 to 4 ton systems. In a climate where the system runs for months, red dust gets into everything, and sizing matters as much as the brand.
We size the system for your home, handle the permit and explain every option before you commit. Emergency service is available 24/7.

Examples of our work
When replacing beats repairing
- The system is 10 to 15 years old or more. Desert run times use equipment up faster.
- It has needed more than one repair recently.
- A compressor or coil is the problem on an older unit.
- Summer bills keep rising, or rooms cool unevenly.
- It uses R-22 refrigerant, which is no longer produced.
Sizing for a desert summer
Capacity should come from the home: floor area, layout, insulation, windows, sun exposure and ducts. Too small and the system never catches up on a 108 degree afternoon.
Too large and it cools in short bursts, never evens out the house and wears faster.
Cooling capacity also drops as the outdoor temperature climbs, so ask any contractor how the unit performs at 105 and 110 degrees, not only at the standard test point.
Dust and the outdoor unit
In this region, fine red dust is a design issue, not just a maintenance one. We place the outdoor unit with airflow and access in mind, keep it clear of dust sources where we can, and show you how to rinse the coil.
Ask about coil protection options and plan a yearly cleaning.
AC or heat pump?
A heat pump cools like an AC and heats through the mild winter, so one system can replace both an AC and a furnace. Many homes here use one. See heat pump installation in Washington.
How a replacement works
- We look at the home and the existing equipment. Ducts, attic, electrical panel and where the units sit.
- We size and select. Capacity from the home, with efficiency options explained.
- You get options and prices. Including duct or electrical work, before work begins.
- We handle the permit. From the city where you live.
- We install, start up and test. Airflow and refrigerant charge are checked, not guessed.
- We walk you through it. Thermostat, filter and what to do when something seems off.
