How do I know if my AC needs repair or replacement?

The repair-versus-replace decision depends on four factors: system age, refrigerant type, repair cost relative to replacement cost, and whether the system has been properly maintained. A general rule of thumb in the industry is the '5,000 rule' — multiply the system's age in years by the repair cost, and if the result exceeds $5,000, replacement is usually more economical than repair. But that rule assumes R-410A or R-454B equipment. For R-22 systems, the equation changes because refrigerant top-offs cost $80–$150 per pound and will continue to be required. We give you the actual numbers during the diagnostic visit so you can make an informed decision rather than one based on pressure tactics.

Why does my air conditioner cool the downstairs but not the upstairs?

The most common cause in south Salt Lake Valley homes is duct imbalance — the upstairs supply runs are undersized relative to the cooling load on the upper floor, which runs higher due to solar gain through roof and attic. A second common cause is insufficient return air on the upper level, which creates positive pressure upstairs and causes conditioned air to leak out of the building envelope rather than circulate. Static pressure measurement across the air handler and individual register airflow readings will identify which condition you have. A third, less common cause in SunCrest and upper-bench homes is that the system was undersized on the original Manual J by a contractor who used square footage rule-of-thumb rather than a calculated load that accounted for the home's west-facing glass and roof heat gain.

What is R-454B and should I be worried about it in my existing system?

R-454B is the refrigerant replacing R-410A in new equipment manufactured after January 1, 2025. If your existing system uses R-410A or R-22, those refrigerants are still serviceable — R-410A is not being banned in existing equipment, only in new equipment manufacturing. R-454B is A2L (mildly flammable), which means any technician servicing an R-454B system must be A2L certified and use A2L-rated leak detection equipment. All of our technicians completed A2L certification before the January 2025 transition. If your system uses R-22, R-410A, or R-454B, we can service it correctly.

How long does a central air conditioning system last in Draper?

A properly installed, properly maintained central air conditioning system in the south Salt Lake Valley typically lasts 15–20 years. 'Properly installed' means Manual J-sized, correctly charged by superheat and subcooling, with a condenser placed away from direct afternoon sun on south- and west-facing walls. 'Properly maintained' means annual pre-season tune-up with capacitor measurement, coil cleaning, and refrigerant charge verification. Systems that were oversized by rule of thumb, charged by pressure alone, placed in high-ambient locations without manufacturer clearance verification, or have missed multiple maintenance seasons routinely fail at 8–12 years.

Do you offer same-day AC repair service?

Yes, subject to technician availability. During peak summer demand (mid-July through mid-August), same-day availability on non-emergency calls can be limited. Our emergency line is staffed 24/7 for no-cool situations with a medically vulnerable household member (infants, elderly, anyone with cardiopulmonary conditions) when indoor temperature exceeds 85°F. For standard repair calls during peak season, we will give you a realistic appointment window rather than a same-day commitment we cannot keep — scheduling you for a confirmed next-day visit is more useful than a same-day commitment that slips to 9 p.m.

Cooling Services — Draper Heating & Air Conditioning

Cooling system failures in the south Salt Lake Valley do not follow a polite schedule. They happen at 96°F on a Saturday afternoon in late July when the condenser dual-run capacitor finally quits after a summer of sustained ambient temperatures that exceeded the component’s rated operating range. They happen in June when the evaporator coil develops a refrigerant leak that was slow-growing since last season, and the system blows warm air the first time you turn it on. They happen at SunCrest on a 92°F August afternoon when the condenser the previous contractor installed on a south-facing wall has been running at an 8°F ambient penalty all summer and finally trips on high pressure.

Our cooling services cover the full lifecycle of residential and light-commercial cooling equipment across Draper, Sandy, Bluffdale, Riverton, South Jordan, and Herriman — from new ACCA Manual J–sized installation through emergency repair, with every service delivered by EPA Section 608 Universal–certified technicians who measure superheat and subcooling on every refrigerant-related call rather than guessing at charge by pressure alone.

The Wasatch Front Cooling Problem

Most national HVAC contractors write their cooling service protocols for the Gulf Coast, the Midwest, or Phoenix. The south Salt Lake Valley is none of those markets, and the differences are measurable:

Elevation and Condenser Performance

The Draper valley floor sits at approximately 4,500 feet above sea level. The SunCrest ridgeline reaches 6,200 feet. Traverse Ridge homes hit 6,400 feet. Air density at those elevations is 15–19% lower than at sea level, which means condenser coils reject heat less efficiently — a condenser rated for a certain capacity at sea level delivers less cooling capacity at elevation. The AHRI efficiency ratings on the box (SEER2 and EER2) are measured at sea level. An R-454B condenser rated at 16 SEER2 at sea level delivers closer to 14.2 SEER2 at SunCrest elevation before accounting for ambient temperature effects. Installers who do not calculate the elevation correction are systematically undersizing cooling equipment for the actual summer load.

South-Facing and West-Facing Condenser Placement

On SunCrest, Corner Canyon, South Mountain, and the upper Sandy benches, homes frequently have their mechanical equipment on south-facing or west-facing walls — the side the builder found convenient, not the side that performs best. In the afternoon when cooling demand peaks, a south-facing condenser in those locations experiences ambient temperatures 8–12°F above the NWS station reading at the SLC International Airport. A condenser rated for operation up to 115°F outdoor ambient can be operating at 118°F on a 98°F July afternoon on a south-facing SunCrest wall. That’s above the manufacturer’s published operating envelope. The system either trips on high pressure or staggers along at degraded capacity while shortening the compressor’s service life.

R-454B Refrigerant Transition

As of January 1, 2025, new residential and light-commercial cooling equipment is manufactured with R-454B refrigerant, replacing R-410A under EPA SNAP Rule 23 and the AIM Act phase-down schedule. R-454B is classified A2L — mildly flammable — which requires specific handling procedures, A2L-rated leak detection equipment, and UL 60335-2-40–compliant electrical components in the equipment cabinet. Our technicians completed A2L certification through Honeywell’s Solstice training program before the January 2025 transition date. If you are getting service quotes from contractors who cannot tell you what refrigerant is in your system or who are still installing R-410A equipment from distributor inventory in 2026, ask them about their A2L certification status.

Cooling Services We Provide

AC Installation

New central air conditioning system installation for existing homes and new construction. Every installation starts with an ACCA Manual J cooling load calculation that accounts for your home’s actual insulation levels, window area and solar orientation, infiltration rate, occupancy, internal heat gains, and — critically — your elevation and the condenser’s placement relative to prevailing afternoon sun. Equipment is selected by ACCA Manual S against the calculated load, not by rule of thumb. R-454B compliant condensers for all new installations. Refrigerant line set vacuum-verified to 500 microns and held 15 minutes minimum before charging. Charge set by superheat and subcooling at actual outdoor ambient on the day of installation.

AC Repair

Cooling system diagnosis and repair by measurement, not assumption. Every AC repair call starts with: capacitor microfarad reading versus nameplate, compressor and condenser fan motor amperage against nameplate FLA, static pressure across the air handler, refrigerant pressures cross-referenced with the manufacturer’s PT chart at actual outdoor ambient, and superheat and subcooling calculation to determine whether refrigerant charge is correct. Written repair quote before any work begins. $89 diagnostic fee applied to the repair total if you proceed on the same visit.

AC Tune-Up

Pre-season cooling system inspection designed to catch the failures that cause emergency calls in July and August. Capacitor measurement, condenser and evaporator coil cleaning, refrigerant charge verification, contactor and disconnect condition, blower motor amperage, drain line flush and trap inspection, thermostat calibration, and filter replacement. Documented service report with all instrument readings retained in your file for manufacturer warranty compliance. The maintenance visit that prevents a $185 capacitor from becoming a $2,400 emergency compressor diagnosis on a 97°F Saturday.

AC Capacitor Replacement

Dual-run and start capacitor replacement with microfarad-verified replacement parts. Capacitor failure is the most common cause of AC no-start calls on hot days in our service area — particularly on south- and west-facing SunCrest, Corner Canyon, and South Mountain condensers where ambient regularly exceeds 105°F in July and August. A capacitor rated for a 65°C operating temperature that runs at 72°C all summer has a service life roughly half what the manufacturer projects at rated temperature. We verify the replacement capacitor’s microfarad reading before installation and confirm proper motor start and run operation after.

AC Compressor Repair

Compressor diagnosis covering locked rotor amperage, single-phasing, refrigerant contamination, valve failure, and winding short-to-ground. Manufacturer warranty claim filing on in-warranty compressors. Hard-start kit installation for compressors showing elevated start amperage draw. Replacement versus repair analysis based on system age, refrigerant type (R-22 systems vs R-410A vs R-454B have different economic equations), remaining manufacturer warranty, and the cost of R-454B equipment conversion if the existing system is R-22 or early-run R-410A.

Refrigerant Recharge

Refrigerant leak detection using electronic leak detector and UV dye confirmation, leak repair, and system recharge to manufacturer specification. EPA Section 608 Universal compliant recovery and recycling on all refrigerant types: R-22, R-410A, and R-454B. We do not top off leaking systems — a refrigerant recharge without finding and repairing the leak is a temporary measure that puts refrigerant back into a system that will leak it out again, shortens compressor life by running the system undercharged between the top-off and the next leak event, and on R-22 systems adds $80–$150 per pound to a system that is already due for replacement evaluation.

Swamp Cooler Service

Evaporative cooler startup, shutdown, pad replacement, pump and motor service, water distribution tray cleaning, and float valve adjustment. Common in pre-1990 Draper, Sandy, and Riverton homes built before central air conditioning was standard in Utah residential construction. Wasatch Front water hardness at 15–25 grains per gallon accelerates mineral scale on evaporative cooler pads, distribution lines, and sump trays significantly faster than the manufacturer’s replacement schedule assumes. We use descaling treatment on water-side components to extend pad and pump service life between replacements.

Evaporator Coil Repair

Refrigerant leak detection on evaporator coils using electronic leak detection and UV dye injection confirmation, coil cleaning, TXV (thermostatic expansion valve) replacement, and coil replacement on failed units. Altitude-corrected refrigerant charge on every coil replacement at SunCrest, Traverse Ridge, and high-bench Sandy installations. Coil cleaning for systems where biological growth or debris accumulation has reduced airflow across the coil surface below the design CFM — a dirty evaporator coil raises suction pressure, reduces latent heat removal, and increases compressor head pressure by more than most homeowners realize from looking at a coil with a flashlight.

Service Brands

We install, service, and repair all major residential cooling brands in our service area. For new installations, our preferred lines are Carrier, Trane, Lennox, Mitsubishi Electric, Daikin, and Bosch — chosen for parts availability through Utah-based distributors, cold-climate variable-capacity performance data, and warranty support quality. For service and repair, we work on all brands including Rheem, Ruud, Goodman, Amana, York, Coleman, Heil, Tempstar, Comfortmaker, Bryant, American Standard, and ductless brands including Mitsubishi, Daikin, Fujitsu, Pioneer, and MRCOOL.
