What Heating Services Does McCormick Offer?
McCormick provides furnace, boiler, and heat pump repair, installation, and maintenance for homeowners throughout Greeley and Northern Colorado. Whether you've lost heat overnight, your system is nearing the end of its lifespan, or you're preparing for another Colorado winter with a seasonal tune-up, we'll help you choose the service that fits your needs.
For more than 20 years, our technicians who live and work in NoCo have repaired aging furnaces, replaced outdated boilers, installed high-efficiency heat pumps, and maintained heating systems built to handle Northern Colorado's demanding winters. Explore the services below to learn more.
Colorado winters put furnaces through months of heavy use. Whether your furnace won't ignite, is blowing cold air, or has reached the end of its service life, we repair and install high-efficiency systems properly sized for Northern Colorado's elevation and heating demands.
No heat, uneven temperatures, strange noises, or frequent cycling are all signs something isn't right. Our technicians diagnose the problem quickly and recommend only the repairs your system actually needs, never unnecessary replacements or high-pressure sales.
If your heating system is over 15 years old, breaking down often, or becoming expensive to operate, replacement may save money in the long run. We'll help you compare your options, explain the pros and cons, and install a system that's properly sized for your home.
Many older Northern Colorado homes rely on hydronic or radiant heating systems. We repair leaking, noisy, or inefficient boilers and install modern high-efficiency models that deliver dependable, even heat throughout the winter.
Heat pumps provide efficient heating through much of the year while also cooling your home during summer. For Colorado's coldest nights, many homeowners benefit from a dual-fuel system that automatically switches to a gas furnace when outdoor temperatures drop.
Most emergency heating calls start with small problems that routine maintenance could have caught early. Our seasonal tune-ups help improve efficiency, reduce breakdowns, and prepare your system before freezing temperatures arrive.
What Makes Heating a Challenge in Colorado?
Heating systems in Northern Colorado work harder than they do in many parts of the country. From high elevation to rapid weather swings, local conditions affect how efficiently your equipment operates and how long it lasts.
High Elevation Changes Equipment Performance
At roughly 4,665 feet above sea level in Greeley, gas furnaces and boilers produce less heat than they would at lower elevations. Proper sizing, derating, and adjustment help maintain comfort while improving efficiency and equipment life.
Fast Temperature Swings
Northern Colorado winters often shift from sunny afternoons into below-freezing nights within hours. Those rapid changes make proper thermostat settings, system sizing, and dependable backup heat especially important for consistent indoor comfort.
Cold Snaps Require Reliable Heating
Sub-zero temperatures place extra stress on heating equipment. Furnaces need dependable ignition systems, while heat pumps often perform best when paired with a gas furnace in a dual-fuel configuration during extreme cold.
Dry Air & Long Heating Seasons
Heating systems may run for months at a time, reducing indoor humidity and increasing wear on equipment. Regular maintenance helps improve efficiency, reduce unexpected breakdowns, and extend system life throughout the season.
Local Emergency Service When You Need It
Because our technicians are based in Greeley, we can respond quickly when homeowners experience a genuine no-heat emergency, even after regular business hours.
