A snapshot of the feedback that keeps us accountable.
"Our AC quit on the hottest weekend of the year and they had a tech out within a couple of hours. Fixed on the first visit and explained everything in terms I could actually understand."
"We've used them for our maintenance plan for two years now and never had a surprise breakdown. Never once felt like I was being upsold on something I didn't need."

After thousands of service calls across District of Columbia, DC, a handful of causes show up again and again.
The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Before the heaviest cooling months hit, it's worth having the refrigerant charge checked, the condenser coils cleaned, and the filter replaced — all of which directly affect how hard the compressor has to work.
Clearing debris, leaves, and overgrown landscaping away from an outdoor condenser unit gives it room to breathe and keeps it running efficiently. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.
