D L HVAC is a California heating and cooling contractor offering AC Services, Heating Services, Ductwork Services, Heat Pumps, Furnace Services, Thermostat Services, Emergency HVAC, and Maintenance & Tune-up. Residential customers make up much of the work, though the same skills apply to the occasional small commercial call. Typical jobs range from diagnosing a weak cooling cycle and checking refrigerant levels to sealing leaky ducts, replacing a failing thermostat, and servicing a furnace before the heating season begins.
The business serves Walnut and nearby communities, so crews are familiar with the local climate, the hot spells that strain older condensers, and the housing styles common in the area. Regular tune-ups help catch small problems before they become expensive breakdowns, and prompt emergency response can keep a household comfortable during a heat wave or cold snap.
D L HVAC holds California state contractor license #1120809 and has been licensed since 2024. Anyone comparing local HVAC pros should request a written estimate, ask about the scope of work, and confirm details directly with the contractor before booking.

What should I check before hiring an HVAC pro?
Confirm the license number, read recent customer reviews, and ask whether the quote includes parts, labor, permits, and any warranty on the work. Get the agreed terms in writing before work starts.
What are signs it is time to call an HVAC professional?
