What should I check before hiring an HVAC professional?

Confirm the license is active, request references or reviews from recent local customers, and make sure the estimate clearly lists the equipment, labor, warranties, and any permit requirements. Be cautious of anyone who pressures you into an immediate decision.

What are signs it is time to call an HVAC professional?

Call a professional if your system produces unusual noises, short-cycles, fails to reach the set temperature, or your energy bills rise without explanation. Uneven room temperatures, a persistent burning smell, or water around the furnace or air handler also warrant prompt inspection.
