Ephraim summers barely ask anything of an air conditioner

Summer afternoons here average 78°F. That is mild, and it means a new air conditioner in Ephraim will spend most of its time running well below its limit rather than straining against the heat.

Any new central air conditioner installed today has to meet a federal minimum of 13.4 SEER2. In a place this mild, that efficiency shows up fast, since the unit is rarely pushed to work hard to keep a home cool.

Utah requires HVAC contractors to hold a state license.

The license comes from the Division of Professional Licensing, and it covers the contractor, not the job itself. The state tested that contractor and keeps them on record for whatever work they take on. Utah does carve out an exception. Work under $7,000 does not need a licensed contractor, so a smaller air conditioner job can fall outside that requirement.

Most cities and counties in Utah require a permit for an air conditioner installation, along with an inspection once the work is finished. That inspection is separate from the state license, and it is what checks the work itself was done right.

What size air conditioner does my house need?
It depends on your home, not a rule of thumb. The right size comes from a load calculation that looks at your square footage, insulation, window area, and layout. Too big and it cools fast but cycles on and off too often. Too small and it runs constantly and still can't keep up on the hottest afternoons. A contractor will run this calculation for your specific house before quoting equipment.
Should I replace the whole system or just the outdoor unit?
In most cases the outdoor unit and the indoor coil need to be matched, so replacing only the outdoor unit can leave you with a mismatched system. A mismatched system runs less efficiently and may not be covered by the manufacturer's warranty. A contractor will check the age and condition of your indoor coil before deciding whether it can stay or needs to go too.
Do HVAC contractors in Ephraim need a state license to work on my home?
Yes. Utah requires HVAC contractors to hold a state license through the Division of Professional Licensing, and that license covers the contractor rather than each individual job. Installing an air conditioner falls under work that needs a licensed contractor here. You'll also need a permit from the local building office and an inspection once the work is done. A contractor will price the job for your specific house.
