Heating

At Gillette Services - Plumbing, Heating and Air Conditioning, we are a locally owned and family-operated company committed to putting our customers and employees first, and we understand exactly what Lehi residents need to stay comfortable through every cold snap. From furnace installations and heat pump upgrades to emergency repairs and seasonal maintenance, we bring fast response times and a genuine sense of responsibility to every job we take on.

Lehi’s unique geography, nestled between Utah Lake and the Wasatch Mountains, means cold air drainage and inversions can make winters feel even more bitter than the forecast suggests. That is why a properly sized and efficiently operating heating system is not a luxury here — it is a necessity. We work closely with each homeowner to evaluate their property, assess insulation levels, and recommend the ideal system for their square footage and lifestyle. We are here to understand and offer personalized service, because no two homes in Lehi have identical heating demands.

Heating Installation and System Replacement

Whether you are building a new home in one of Lehi’s many expanding neighborhoods or replacing an aging furnace in a well-established area, installation quality determines how well your system performs for the next fifteen to twenty years. We begin every installation project with a detailed Manual J load calculation, which accounts for your home’s orientation, window placement, insulation R-values, and occupancy patterns. This ensures the unit we install is neither oversized nor undersized, both of which can lead to comfort problems and premature wear.

Modern furnaces now achieve Annual Fuel Utilization Efficiency ratings of 95 percent or higher, meaning nearly every dollar you spend on natural gas is converted into usable heat. We install high-efficiency gas furnaces, dual-fuel systems, and electric heat pumps that leverage the latest variable-speed blower technology and modulating gas valves. These systems adjust output in small increments rather than cycling fully on and off, which reduces temperature swings and lowers monthly utility costs. Our community roots run deep — our community initiatives include providing free furnace installations to families in need during the winter season, contributing to the HVAC installation for the St. Jude Dream Home, and supporting the Children’s Justice Center’s new facility.

Heating Repair and Diagnostics

A heating system failure in the middle of a Lehi winter demands urgent attention. We offer fast response times because we know that every hour without heat puts your family and your plumbing at risk. Our technicians arrive equipped with diagnostic tools, common replacement parts, and the training to troubleshoot a wide range of issues on the spot. From faulty ignitors and cracked heat exchangers to malfunctioning thermostats and blower motor failures, we isolate the root cause before recommending any repair.

We are reliable, and that means we give you honest assessments. If a repair can safely extend the life of your system by several years, we will tell you. If the cost of repair approaches half the value of a new unit, we will walk you through your replacement options so you can make an informed decision. Transparency is part of who we are as your homegrown service pros.

Preventive Maintenance for Lehi Homeowners

Routine maintenance is the single most effective way to protect your heating investment. Industry data from the U.S. Department of Energy shows that regular tune-ups can improve system efficiency by five to fifteen percent and significantly reduce the likelihood of mid-season breakdowns. Our maintenance visits include a thorough checklist designed to catch small issues before they become expensive emergencies.

1. Inspect and clean the burner assembly to ensure even flame distribution and safe combustion
2. Test the heat exchanger for cracks or corrosion that could allow carbon monoxide to enter your living space
3. Check electrical connections and thermostat calibration to verify accurate temperature control
4. Lubricate moving components and evaluate blower performance to reduce friction and energy waste
5. Replace or clean the air filter to maintain healthy airflow and indoor air quality

Serving the Lehi Community with Pride

We take great pride in serving our community and giving back whenever possible. In addition to our charitable partnerships, we actively participate in and donate to various other local programs and charitable initiatives throughout the year. Every service call we complete in Lehi reinforces our commitment to the neighborhoods we call home.
