FAQs
What does it mean that your technicians are “factory-trained,” and why does it matter for my air conditioner?
Factory-trained technicians have completed hands-on courses provided by the manufacturers of the equipment we install and service. They are tested on correct installation procedures, diagnostic techniques, warranty requirements, and the latest updates for each model line. For you, this means faster, more accurate repairs, protection of your manufacturer’s warranty, and peace of mind that your system is being handled exactly as the factory intended.
Which air-conditioning brands and system types do you service in Signal Mountain?
Because our technicians are factory-trained by multiple manufacturers, we can service and install virtually every major brand sold in the Chattanooga/Signal Mountain area, including Trane, Carrier, Lennox, Rheem, Goodman, American Standard, Bryant, and Mitsubishi. We also work on central split systems, heat pumps, ductless mini-splits, packaged rooftop units, and high-efficiency variable-speed systems.
How often should my AC unit be serviced, and what is included in a preventive-maintenance visit?
For most homes in Signal Mountain, we recommend a full tune-up each spring before the heavy cooling season starts. During a maintenance visit we (1) clean the condenser and evaporator coils, (2) check refrigerant charge, (3) tighten electrical connections, (4) test capacitors and contactors, (5) flush the condensate drain, (6) lubricate moving parts, (7) calibrate the thermostat, and (8) run a full performance test. Regular maintenance can lower energy bills by up to 15 %, extend equipment life, and keep your warranty in force.
Do you offer 24/7 emergency air-conditioning repair in Signal Mountain, and what counts as an emergency?
Yes. Our on-call team is available day or night, weekends and holidays. Examples of true emergencies include complete loss of cooling during extreme heat, electrical smells or sparking at the outdoor unit, refrigerant leaks that trigger low-pressure lockouts, and any situation involving smoke or burning odors. For non-urgent issues—such as poor airflow or unusual noises—we can schedule a same-day or next-day appointment during normal business hours to save you after-hours fees.
Can your technicians help me improve energy efficiency and lower my cooling costs?
Absolutely. During any service or maintenance visit we can perform an energy assessment that includes duct-leak testing, thermostat programming, airflow balancing, and SEER comparisons between your current unit and today’s high-efficiency options. We also advise on insulation upgrades and smart-thermostat integration. Many clients in Signal Mountain cut summer energy use by 20-30 % after these improvements.
What is the typical process and timeline for a new AC installation or replacement?
A standard replacement begins with a free in-home evaluation where we measure load requirements and discuss comfort goals. Once you approve the proposal, we pull any required Signal Mountain permits and schedule installation—usually within 2–5 business days. On installation day we remove the old equipment, set and level the new condenser, install the indoor coil or air-handler, replace the line set if necessary, evacuate and charge the system, connect the thermostat, and run a start-up verification. Most jobs are completed in a single day, and you receive all warranty papers plus a walkthrough of the new system’s operation.
