Twice a year is the right cadence for most Manitou Springs homes with both heating and cooling systems: a heating tune-up in fall and a cooling tune-up in spring. At 6,300 feet, your heating system runs from October through April and accumulates significant hours over a long season. Annual maintenance keeps combustion quality in check, catches developing issues early, and protects equipment warranties on newer systems.

A heating tune-up covers filter replacement, burner inspection and cleaning, heat exchanger inspection, flue and venting check, altitude adjustment verification, combustion analysis and CO test, thermostat calibration, and blower motor inspection. A cooling tune-up covers filter replacement, refrigerant pressure check with altitude adjustment, condenser coil cleaning, evaporator coil and drain line inspection, capacitor and contactor testing, and thermostat calibration. Both visits include an honest condition report on your system’s overall health.

Gas furnaces have a gas valve that controls fuel delivery. At altitude, the correct fuel delivery rate is lower than at sea level because there’s less oxygen available for combustion. Altitude adjustment means verifying and correcting the gas valve derate setting so the furnace burns the right amount of fuel for Manitou Springs elevation. A furnace running without this adjustment burns inefficiently and may produce carbon monoxide. WireNut checks this on every heating maintenance visit in Manitou Springs.

Yes. Most equipment warranties require annual maintenance to remain valid. Beyond warranty protection, newer systems still accumulate wear, still need combustion quality verification at altitude, and still develop issues that are much less expensive to address during a maintenance visit than during an emergency repair call. Newer equipment in Manitou Springs doesn’t get a pass on altitude adjustment checks just because it’s new.

September or early October for heating maintenance, before the first significant cold spell. March or April for cooling maintenance, before summer hits. The worst time to discover your furnace has a problem is the first cold night of the season. The best time to find it is during a maintenance visit six weeks earlier. WireNut tends to get busy with heating calls in late October and November, so scheduling ahead in September gets you in before the rush.

Filter replacement is the most impactful homeowner maintenance task and you absolutely should do it yourself on the schedule your system requires, typically every 1 to 3 months depending on filter type and home conditions. Keeping the outdoor AC or heat pump condenser clear of debris is another straightforward homeowner task. Everything beyond those, including combustion analysis, refrigerant checks, heat exchanger inspection, and altitude adjustment verification, requires professional training and equipment. Don’t skip professional maintenance because you’ve been changing your own filters.

In the short term, probably nothing obvious. Over time, skipped maintenance leads to reduced efficiency and higher operating costs, developing issues that become more expensive to repair as they progress, and eventually a system failure that tends to happen at the worst possible time. In Manitou Springs, a furnace that hasn’t been maintained and hasn’t had its altitude adjustment checked may be running with combustion quality issues that are both inefficient and potentially producing carbon monoxide without any obvious symptoms until something fails. Annual maintenance is the insurance against all of that.
