FAQs
Why is an annual AC tune-up important for homes in Signal Mountain?
Signal Mountain’s elevation and rapidly changing weather place extra stress on central air systems. An annual tune-up keeps components clean and properly adjusted so your unit can handle high humidity in July and cool nights in April. Regular maintenance also preserves the manufacturer’s warranty, prevents 80-90 % of unexpected breakdowns, and can add 3–5 years to the life of your equipment.
What tasks are included in your AC tune-up service?
Our NATE-certified technician follows a 20+ point checklist that includes: • Comprehensive safety inspection • Refrigerant level and pressure check • Cleaning of condenser coils and evaporator coil surface • Tightening of electrical connections and testing of capacitors, contactors, and relays • Calibration of thermostat and verification of temperature split • Lubrication of all moving parts • Clearing and treatment of the condensate drain to prevent algae growth common in our humid climate • Inspection of ductwork and air filter for airflow restrictions • Written performance report with any repair recommendations.
How long does a typical tune-up visit take and will I need to be home?
Most visits take 60–90 minutes per system. We schedule two-hour arrival windows and call or text 30 minutes before we arrive. Someone 18 or older should be present at the beginning and end of the visit so the technician can gain access, review findings, and answer questions, but you are free to work remotely or run errands during the service.
Can a tune-up really lower my summer energy bills?
Yes. Dirty coils, low refrigerant, or a loose electrical connection can reduce efficiency by 15–25 %. After a tune-up, systems typically regain their original SEER rating, translating to noticeable savings during Signal Mountain’s long cooling season. Home-energy studies show the modest cost of a tune-up is usually recouped in utility savings within one summer.
When is the best time of year to schedule a tune-up in Signal Mountain?
We recommend booking in early spring—March or April—before you rely on the AC daily. Scheduling ahead ensures appointment availability, avoids emergency fees, and gives you time to address any repairs before peak heat. If you missed spring, any time is better than skipping a year; we perform tune-ups year-round.
How much does an AC tune-up cost and are there any specials for Signal Mountain residents?
A single-system precision tune-up is $99, which includes all labor, testing instruments, and standard drain-line treatment. Additional systems in the same home are $79 each. We offer a $20 discount for first-time Signal Mountain customers and 10 % off for seniors and active-duty military. Joining our Comfort Club maintenance plan reduces each tune-up to $69 and includes priority scheduling and a 15 % repair discount.
