Frequently Asked Questions

Utah's extreme seasonal range—summer highs over 95°F and winter lows below 10°F—requires systems that handle both heating and cooling loads without oversizing. Oversized equipment cycles too frequently, reducing efficiency and lifespan. Proper sizing accounts for insulation, orientation, and both seasonal peaks to maintain year-round comfort.

If your system is over 15 years old and repair costs exceed 50% of replacement value, replacement typically makes financial sense. Aging systems lose efficiency, use outdated refrigerants, and face increasing part failures. Factor in rising energy bills and frequency of recent repairs when deciding.

Heat pumps require ductwork and condition the entire home through a central unit. Mini-splits are ductless, offering zoned control for individual rooms or additions. Both provide heating and cooling, but mini-splits install faster in spaces without existing ducts and allow different temperature settings per zone.

These spaces typically lack ductwork, making traditional HVAC extensions expensive and disruptive. Mini-splits mount directly on walls with only a small refrigerant line penetrating exterior walls. They provide both heating during Utah winters and cooling during summer without modifying existing duct systems or losing conditioned air to unconditioned attics.

Blocked vents, undersized ductwork, leaking ducts in attics or crawlspaces, and improper system zoning all create hot and cold spots. Air balancing issues occur when supply registers don't match room heating and cooling loads. Rooms over garages or on upper floors often show the biggest temperature differences.

Annual pre-season inspections in spring catch minor issues before temperatures spike above 90°F. Technicians clean coils, test refrigerant charge, check electrical connections, and verify airflow during tune-ups. These checks prevent mid-season breakdowns when repair demand is highest and outdoor temperatures make system failures uncomfortable.

Technicians inspect and clean critical components, test system operation under load, check refrigerant levels, verify electrical connections, measure airflow, and examine heat exchangers or coils for wear. Testing identifies performance issues before they cause failures. Documentation tracks system condition over time and flags components nearing end of service life.

Complete replacement includes removing old equipment, sizing new systems to current heating and cooling loads, installing indoor and outdoor units, connecting refrigerant lines, integrating with existing ductwork or installing new runs, wiring thermostats, testing operation, and verifying airflow meets design specifications.

Scheduled inspections identify worn components before they fail during business hours. Replacing belts, capacitors, and contactors during planned maintenance prevents unexpected shutdowns that disrupt operations. Regular filter changes and coil cleaning maintain airflow, preventing strain that accelerates equipment wear and triggers emergency service calls.

Restricted airflow signals clogged filters, blocked return grilles, closed dampers, undersized ductwork, or blower motor issues. Dirty evaporator coils also restrict air movement. Reduced airflow forces systems to run longer, increases energy use, and causes uneven heating or cooling. Frozen coils during cooling season often result from airflow restrictions.

Low refrigerant from leaks, restricted airflow from dirty filters or blocked returns, and malfunctioning blower motors all drop coil temperatures below freezing. Ice buildup blocks airflow further, compounding the problem. Systems blow warm air and lose cooling capacity until the ice melts and underlying issues are corrected.

Yellow or flickering pilot flames instead of steady blue, unusual odors when heating starts, delayed ignition or frequent cycling, uneven heating between rooms, and increasing energy bills all indicate problems. Strange noises like banging or squealing signal mechanical issues. Address these before temperatures drop and heating becomes essential.

Many AC complaints — short cycling, rooms not reaching the set temperature, or the system not turning on — actually trace back to the thermostat rather than the unit itself. Signs include the thermostat screen going blank, a temperature reading that doesn't match the room, or the AC not responding to setting changes. A proper diagnostic checks the control side first before opening the equipment.

Misdiagnosing a thermostat problem as a mechanical AC failure can lead to unnecessary parts replacement and repeated service calls. A technician who troubleshoots the electrical and control side accurately saves time and money by fixing the real cause on the first visit, which matters especially during West Valley City's peak summer heat.

Look for a company that handles the full control-and-equipment relationship — one that can diagnose whether a symptom originates in the thermostat, the wiring, or the AC unit itself. A team experienced in both sides of the system avoids the guesswork that leads to repeat visits and unresolved comfort problems.

Yes, True HVAC provides 24/7 emergency and same-day AC repair for both residential and commercial customers in West Valley City and the surrounding Utah communities. Technicians are available around the clock, so you're not left waiting through a hot Utah night or a full business day when your system goes down.

Call True HVAC any time of day or night — the team handles after-hours emergencies and can dispatch a technician to your location. When you call, have your address, a brief description of the problem, and your system's make and model ready so the technician arrives prepared to get your AC running as quickly as possible.
