About DNGHVAC inc.

Air conditioners, furnaces and the ducts between them are the kind of work DNGHVAC inc. is listed for in Lawrenceville. Time in business: 9 years. The business lists 3 people on staff.

The listing includes AC repair. Low refrigerant usually means there is a leak somewhere, so it is fair to ask whether a repair will find and fix the leak or only recharge the system.

New systems should be sized to the house, which depends on its square footage, insulation, windows and layout. Ask how the size of any proposed system was worked out, and whether anyone measured the rooms.

Warm air from the vents, an outdoor unit that will not start, ice on the lines and water around the indoor unit are the usual reasons people call.

Posted hours: all day, every day. It is based in Lawrenceville; for Suwanee, Dacula and Duluth and other towns nearby, ask first.

Before you call DNGHVAC inc., check the thermostat settings, the filter and the breakers, and mention what you checked so the visit starts in the right place. Booking maintenance before the season starts usually means more flexible scheduling than waiting for a breakdown in a heat wave.
