Regular maintenance is the single best way to extend the life of your HVAC system and avoid costly breakdowns. Our comprehensive tune-up covers everything from coil cleaning to refrigerant checks.
Preventive AC maintenance in Plano, TX is the single best investment you can make to avoid emergency repairs. United National HVAC recommends twice-yearly tune-ups in Collin County — once in spring before cooling season and once in fall before heating season.
Homes in Legacy West, West Plano, and East Plano and throughout Plano (75023/75024/75025/75074/75075/75093) run their AC hard from April through October. That kind of runtime puts stress on every component — coils, capacitors, motors, and drain lines. Catching issues during a $100 tune-up beats a $1,500 emergency repair call in July.
Our maintenance visit includes cleaning evaporator and condenser coils, checking and topping refrigerant, testing capacitors and contactors, clearing the condensate drain, lubricating the blower motor, calibrating the thermostat, and replacing the air filter. You'll get a full written report of everything we found.
