AC & Heating Tune-Up

Our AC tune-up is timed for spring, preparing your cooling system for Nashville's demanding summer. The service begins with a thermostat check, verifying calibration and proper operation in cooling mode. We inspect the air filter and replace it if needed. At the outdoor condenser unit, we clean the condenser coil, removing dirt, debris, and biological growth that restrict airflow and reduce heat transfer. We straighten bent fins and clear vegetation from around the unit. We inspect the refrigerant lines for damage, insulation deterioration, and oil spots that may indicate leaks. We measure refrigerant charge using digital manifold gauges and compare pressures to manufacturer specifications.

Proper refrigerant charge is critical for efficiency and compressor longevity. On a 95-degree Nashville day, even a 10 percent undercharge reduces cooling capacity by approximately 20 percent. We test the capacitor with a capacitance meter because a weakening capacitor is one of the most common causes of mid-summer breakdowns. We measure amperage draw on the compressor and fan motors to identify components that are working harder than they should. We inspect and tighten all electrical connections, since loose connections cause arcing, heat buildup, and eventual failure. Inside, we check the evaporator coil for dirt buildup and clean it as needed.

We inspect the condensate drain line and pan, clearing any clogs and treating the line with an algaecide to prevent future blockages. We verify blower motor operation, check the blower wheel for dirt buildup, and measure airflow across the evaporator coil.

The return on investment from annual HVAC tune-ups is substantial and well documented. Energy savings alone often pay for the tune-up cost. The Department of Energy reports that proper maintenance can reduce HVAC energy consumption by 15 to 25 percent. On an average Nashville energy bill where HVAC accounts for roughly half the total, that translates to meaningful monthly savings. Breakdown prevention is perhaps the most valuable benefit. Approximately 80 percent of HVAC system failures are caused by issues that would be caught during a routine tune-up. A failing capacitor costs $200 to replace during a maintenance visit but $400 or more as an emergency repair on a Saturday afternoon in July.

A dirty flame sensor costs almost nothing to clean during a tune-up but can leave your family without heat on a freezing night if it causes a lockout. Equipment longevity is directly tied to maintenance. The average HVAC system lasts 15 to 20 years with regular maintenance but may fail in 10 to 12 years without it. On a system that costs $6,000 to $12,000 to replace, those extra years of service represent thousands of dollars in value. Warranty protection is a practical benefit. Most manufacturers require annual professional maintenance as a condition of their warranty. Without maintenance records, a warranty claim may be denied even if the equipment is within the warranty period.

Safety is paramount for gas heating systems. Carbon monoxide from a cracked heat exchanger, gas leaks from deteriorating fittings, and electrical hazards from damaged wiring are all risks that annual inspection helps prevent.

A comprehensive HVAC tune-up in Nashville typically costs $89 to $149 for a single system. This investment is modest compared to the costs it helps you avoid. Consider that a single emergency repair averages $350 to $800. The monthly energy savings from a properly maintained system typically add up to $10 to $30, which means the tune-up often pays for itself in energy savings alone within the first year. For homes with two systems, such as a separate upstairs and downstairs system, we offer discounted pricing on the second system. Our maintenance plan customers receive their tune-ups as part of their plan at an even lower effective cost, along with repair discounts, priority scheduling, and other benefits.

We also offer a tune-up guarantee. If your system breaks down within 30 days of a tune-up and the issue is related to a component we inspected, we will apply the tune-up cost toward the repair. This demonstrates our confidence in the thoroughness of our service and our commitment to your satisfaction.
