FAQs About AC Maintenance
How often should I schedule AC maintenance?
We recommend scheduling a professional AC tune-up once a year, ideally in the spring before peak summer heat arrives.
Does AC maintenance really reduce energy bills?
Yes. A clean, well-maintained system runs more efficiently and uses less energy to cool your home, which can lead to lower utility bills.
How long does an AC tune-up take?
Most maintenance appointments take about 60–90 minutes, depending on system condition and accessibility.
What happens if I skip AC maintenance?
Skipping annual maintenance increases the risk of breakdowns, decreases energy efficiency, and shortens the lifespan of your AC system.
Do you service both residential and commercial systems?
Yes. We provide AC maintenance and tune-ups for homes, offices, retail spaces, and other commercial properties across Gaithersburg and DC.
