HVAC maintenance is important at any elevation, but Monument’s 7,000 feet adds specific factors that make it more critical here. Combustion appliances, furnaces and boilers, need to be tuned for our lower oxygen levels or they run inefficiently, produce elevated CO levels, and wear out faster than systems properly adjusted for altitude. AC systems and heat pumps need refrigerant charge verified for Monument’s elevation or they underperform in ways that look like equipment failure but are actually setup issues. These altitude-specific checks are not extras on a WireNut Monument maintenance visit. They are the standard, because they matter here in ways they simply do not at lower elevations.

If your system has a specific problem that needs repair rather than maintenance, our AC repair service handles cooling issues and our heating repair service covers heating system problems. See the full Monument HVAC services page for everything we offer.

• Altitude-adjusted combustion analysis on furnaces and boilers, checking air-to-fuel ratio and CO output at Monument’s elevation rather than applying sea-level benchmarks that do not apply here.
• Refrigerant level verification for AC systems and heat pumps using Monument-specific pressure readings, since standard sea-level refrigerant charge measurements will produce incorrect assessments at 7,000 feet.
• Heat exchanger inspection on furnaces for cracks or deterioration that could allow combustion gases to mix with the heated air supply, which is a CO safety concern at any elevation but particularly important in Monument.
• Electrical connection inspection and tightening on all HVAC components, since loose connections are a leading cause of component failures.
• Filter condition assessment and airflow measurement, since restricted airflow from a dirty filter affects efficiency and can cause overheating and component failure.
• Condenser and evaporator coil inspection and cleaning on AC systems and heat pumps to maintain heat transfer efficiency through Monument’s cooling season.

Here is what our certified HVAC technicians actually check and do during a maintenance visit in Monument.

WireNut offers maintenance plans for Monument homeowners who want to make sure their HVAC systems are serviced consistently each year without having to remember to schedule it before each season. Ask your WireNut technician about available maintenance plan options during your first service visit to your Monument home.
