Marcus T.Trolley Square, Wilmington (19806)
Fast response during the July heatwave
Our central air conditioner started blowing warm air on an 92-degree Saturday afternoon. Called the request line and was connected with an independent technician who arrived in less than two hours. He diagnosed a failed dual run capacitor, checked refrigerant pressures, and had cold air flowing again within 30 minutes. Upfront pricing before starting.

Seamless heat pump upgrade with Energize Delaware rebates
Replaced our 18-year-old gas furnace and AC pair with a high-efficiency inverter heat pump. The matched contractor did a thorough Manual J calculation, explained the Energize Delaware rebate paperwork step by step, and completed a very tidy installation with new disconnect and pad.
Robert M.Highlands, Wilmington (19806)
Quiet radiators and proper steam balancing
Our 1920s brick home had banging steam pipes and cold second-floor radiators. Finding someone who understands older steam systems in Wilmington is tough. The provider cleaned the sight glass, replaced three stuck air vents, adjusted the pressuretrol setting, and explained how to skim the boiler. The house is finally quiet and evenly warm.
