Our Air Conditioning Replacement Services in Lehi UT

We install and replace a wide range of cooling systems for Lehi homeowners. Here’s what we offer.

Central AC Replacement

When your central air conditioner has run its course, we replace it with a properly sized, SEER2-compliant system matched to your home’s ductwork and load. All new central AC installations in northern Utah meet the 2026 minimum efficiency standard of 13.4 SEER2. Every HVAC unit uses the updated A2L refrigerant formulations (R-454B and R-32) required on new equipment.

Heat Pump Replacement

Heat pumps are a popular choice for homeowners seeking to heat and cool with a single system. We install cold-climate heat pumps designed to perform reliably during Utah’s deep winter inversions. 

Ductless Mini-Split Air Conditioning Replacement

If your home has a ductless system that’s reached the end of its life, or if you’re adding a zone without ductwork, we are the HVAC experts to call. We install replacement mini-split and multi-zone systems built for the Utah weather. Ductless mini-split systems are ideal for homes looking for room-by-room temperature control.

Air Handler Replacement

If your indoor air handler is aging or mismatched to a new outdoor unit, we replace it with a properly matched variable-speed or multi-stage unit. A matched air handler improves efficiency, reduces temperature swings, and extends the life of your new system.

Evaporator Coil and Condenser Replacement

Sometimes the right move isn’t replacing the entire system, just the coil or condenser that’s failed. We replace evaporator and condenser coils across a wide range of residential air conditioning systems, always verifying compatibility with your existing equipment before work begins.

Smart Thermostat Integration

Every air conditioner replacement includes the option to upgrade your thermostat. We install smart thermostats that connect with your new system, giving you remote access and efficiency insights that help lower your utility bills over time.

Should You Replace Your AC?

Not every HVAC problem calls for a full system replacement. If there is a single failed component on a young, healthy unit, a minor refrigerant recharge issue, or a straightforward fix, an air conditioning repair is the smart choice.

But some situations clearly point toward a new HVAC system. Here’s how to tell the difference.

Signs to Replace Your AC

• Your system is 15 or more years old and struggling to keep up
• Repair costs are approaching 50% or more of what a new system would cost
• You’ve needed multiple air conditioner repairs in a single season
• Energy bills keep climbing despite regular maintenance
• Your system still uses R-22 (Freon) refrigerant, which is no longer being manufactured
• Rooms in your home have persistent hot or cold spots that the system can’t resolve
• The compressor has failed or needs replacement on an older unit
• Your system can’t consistently reach your thermostat setting during Lehi’s 100°F+ summer heat

Not sure which way to go? We’ll come out, diagnose the issue, and give you honest advice on whether to repair or replace. 

Benefits of a New AC Unit

Upgrading to a new, properly sized air conditioner does more than just restore cooling. Here’s what Lehi homeowners typically gain.

• Lower energy bills: Modern systems with high SEER2 ratings use less electricity to cool your home than a unit from 10 or 15 years ago.
• Consistent comfort: A correctly sized system, calculated using the Manual J load calculation, eliminates hot spots, warm air, humidity swings, and uneven airflow.
• Cleaner air: New systems pair seamlessly with upgraded filtration options, including MERV-13, HEPA, and UV air purifiers, to reduce dust, allergens, and contaminants.
• Best-in-class warranty protection: Qualifying new HVAC installations come with a 10-year parts-and-labor warranty, one of the strongest in the industry.
• Fewer breakdowns: A new system with a fresh warranty means no more planning your summer around whether the AC will hold up.
• Increased home value: A modern, high-efficiency HVAC system is a genuine selling point.
• Rebates and tax credits: New qualifying heat pumps and high-efficiency systems may be eligible for the Federal 25C Tax Credit and Wattsmart or ThermWise rebates.

• High-efficiency heat pump installation: $8,500 to $14,000+

We’ll walk you through what’s available during your estimate appointment so you can see the full picture, including installation costs, potential rebates, and monthly payment options.
