Utah's Heat Pump Specialists
Why Heat Pump Service in Utah Requires Local Know-How
Air-source heat pumps behave differently at elevation. In communities like Kamas, Heber, and Midway, thinner air affects how efficiently your system transfers heat, and the extreme temperature swings common to mountain climates put extra strain on compressors and refrigerant circuits. A technician applying standard valley-grade sizing or charging procedures to a mountain property is setting that system up to underperform. At Keystone, our 20-plus years of experience across the Wasatch Front means we account for altitude, load demands, and local climate realities every time we service a heat pump. You get a system that is properly sized and calibrated for where you actually live.


Honest Diagnosis, No Pressure
What to Do When Your Heat Pump Is Not Heating
A heat pump not heating is one of the most common calls we receive heading into fall and winter. The causes range from low refrigerant and a failed reversing valve to a tripped breaker or a defrost cycle issue. Our diagnostic process covers ductwork, refrigerant levels, and all electrical components before we make any recommendation. We explain what we find in plain language, without jargon or pressure, so you can make an informed decision about repair or replacement. If your existing system can be brought back to full efficiency, we will tell you that honestly, even when a replacement would be the more profitable option for us.

The Value of Heat Pump Seasonal Maintenance
Heat pumps work harder than most people realize. They run in heating mode through Utah winters and switch to cooling mode during summer peaks, cycling through temperature swings of 50 degrees or more each season. Without regular heat pump seasonal maintenance, coils get dirty, refrigerant levels drift, and small electrical issues become expensive failures. Our seasonal tune-ups include coil cleaning, refrigerant leak checks, electrical component testing, and a full cycle test before we leave. Scheduling a spring check before summer and a fall check before the first freeze keeps your system running at peak efficiency and extends its useful life. We also handle any applicable utility rebate paperwork for high-efficiency upgrades, removing that administrative burden from your plate.


Built for Mountain Climates
Heat Pump Efficiency Repair and Replacement Done Right
When a repair is no longer the smart financial move, we help you select and install a replacement system sized correctly for your home and elevation. Our heat pump efficiency repair and replacement work covers both traditional split systems and ductless mini-split setups, making us a strong fit for home additions, basement finishes, and properties without central ducting. We coordinate all municipal permits, manage the installation in as little as one day, and walk you through the system before we leave. Customers throughout Sandy, West Jordan, Draper, Park City, and the Kamas Valley have saved thousands compared to bids from larger regional competitors, getting higher-efficiency equipment at a price that actually reflects the market.

Frequently Asked Questions About Heat Pump Service
How often should a heat pump be serviced in Utah?
Most heat pumps in Utah benefit from two service visits per year: once in spring before cooling season and once in fall before heating season. Because heat pumps run in both heating and cooling modes, they accumulate wear faster than a furnace or AC unit that only operates half the year. Utah's dusty summers and freezing winters add extra stress on coils and electrical components. A twice-yearly tune-up catches small issues like refrigerant drift or dirty coils before they turn into costly breakdowns during peak demand periods.Why is my heat pump running but not producing heat?
A heat pump that runs but fails to produce heat is usually dealing with one of a few issues: low refrigerant charge, a faulty reversing valve stuck in cooling mode, a defrost cycle problem, or an electrical fault. In mountain areas like Heber or Kamas, altitude-related refrigerant behavior can also cause performance drops that would not occur at lower elevations. A proper diagnosis should cover refrigerant levels, electrical components, and ductwork before any recommendation is made. Avoid technicians who guess or push replacement without a thorough inspection.Do heat pumps perform well at high elevations like Heber or Kamas?
Yes, but they need to be properly sized and charged for altitude. At elevations of 5,800 feet and above, thinner air affects how efficiently a heat pump transfers heat, and standard sizing calculations used for valley homes can result in a system that is undersized for mountain conditions. Keystone specializes in altitude-specific load calculations and refrigerant charging procedures to make sure systems in Heber, Kamas, Midway, and surrounding communities perform correctly through extreme seasonal temperature swings.What does a seasonal maintenance visit from Keystone include?
A standard seasonal maintenance visit covers coil cleaning, refrigerant leak detection and level checks, electrical component testing, blower inspection, ductwork assessment, and a full cycle test at the end. We also check safety controls and verify the defrost cycle is functioning correctly for winter operation. Before leaving, we walk you through the findings in plain language and let you know if anything needs attention. The goal is to catch small issues early and keep the system running at peak efficiency throughout the season.Can a heat pump replace both my furnace and air conditioner?
In many cases, yes. Modern air-source heat pumps provide both heating and cooling from a single system. For Utah climates, particularly in the Salt Lake County valley areas, a properly sized heat pump can handle year-round comfort needs. In higher-elevation communities where temperatures drop well below freezing for extended periods, some homeowners opt for a dual-fuel setup that pairs a heat pump with a gas furnace for backup heating during the coldest stretches. We assess your home, location, and existing setup to recommend the configuration that makes the most sense.Does Keystone install ductless mini-split heat pumps?
Yes. Ductless mini-split systems are a strong option for home additions, basement finishes, master suites, and properties without existing central ductwork. Keystone installs multi-zone mini-split setups that allow you to control temperatures independently in different areas of the home. These systems are especially useful in older ranch-style homes where adding or extending ductwork is impractical. We size the system for your space and elevation, handle all permits, and complete most installations in a single day.Does Keystone handle utility rebate paperwork for heat pump installations?
Yes. High-efficiency heat pump installations often qualify for rebates through local utility providers, but the paperwork and submission process can be confusing. Keystone handles that process directly on behalf of the customer as part of the project, so you receive the financial benefit without the administrative hassle. This is part of how we act as a financial advocate for our customers rather than just a mechanical service provider.How much could I save by choosing Keystone over a larger HVAC company for heat pump replacement?
Savings vary by project, but customers have documented significant differences. One verified case showed a Keystone bid coming in $8,000 lower than a major regional competitor for a higher-efficiency system. Larger companies often carry inflated overhead costs that get passed to the customer. Keystone operates as a locally owned business without the advertising and franchise fees that drive up competitor pricing. We also handle utility rebate paperwork for qualifying installations, which can add further savings beyond the initial equipment and labor cost.
