Centennial’s older housing stock means many homes have HVAC systems that are approaching or past the typical service life for their equipment type. Annual maintenance is how you maximize the useful life of aging equipment, catch developing problems before they become emergency failures, and keep efficiency from degrading as components wear. A furnace that has not been cleaned or inspected in five years is running harder than it should, costing more in gas, and accumulating risk that shows up as a mid-winter breakdown.

For the AC side of the system, our AC maintenance service handles spring tune-ups specifically focused on the cooling system. For homes where the most recent maintenance visit revealed repair needs, our heating repair and air conditioning repair teams handle follow-up work. See all Centennial HVAC services we offer.

• Furnace or heat pump heating tune-up in the fall before heating season, including burner cleaning, heat exchanger inspection, igniter test, gas pressure check, and safety control verification.
• AC or heat pump cooling tune-up in the spring before cooling season, including coil cleaning, refrigerant check, electrical inspection, and airflow verification.
• Filter evaluation and replacement with a recommendation for the right filter type for your Centennial home’s system and a schedule for replacement.
• Thermostat calibration and control verification to confirm the system is responding correctly to thermostat calls for heating and cooling.
• Blower motor and belt inspection to catch worn or failing components before they cause a system failure.

Here is what WireNut covers during HVAC maintenance visits in Centennial.

What Does HVAC Maintenance Actually Prevent in a Centennial Home?

Annual HVAC maintenance prevents the most common mid-season failures that leave Centennial homeowners without heat in January or cooling in July. Igniter failure in furnaces is one of the most predictable and preventable failures: igniters degrade over time, and a maintenance visit that catches a weakening igniter allows for proactive replacement before it fails completely at the worst possible time. Dirty evaporator coils that are allowed to build up over years of operation are a common cause of AC failures in summer that could have been prevented with annual coil cleaning.

Beyond emergency prevention, maintenance keeps energy consumption from creeping up as systems work harder to compensate for reduced efficiency from dirty components or low refrigerant. A furnace that has not been cleaned in three years may be running 10 to 15 percent less efficiently than it should, costing Centennial homeowners real money on monthly gas bills.

How Often Should I Change My HVAC Filter in Centennial?

Filter replacement frequency depends on the filter type, the number of people and pets in the home, and whether anyone has allergies or respiratory sensitivities. Standard one-inch fiberglass filters should be replaced every 30 days. Higher-MERV pleated filters last 60 to 90 days. Centennial’s dry climate means more airborne dust than in more humid regions, which can shorten filter life. A clogged filter is the number one cause of HVAC system problems, including the overheating that trips limit switches and causes furnaces to shut down.

WireNut technicians check filter condition during every maintenance visit and advise on the right filter type and replacement schedule for your specific system. A filter that is too restrictive for your system’s blower can reduce airflow and cause the same problems as a clogged filter, so matching filter to system matters.
