FAQs

HVAC FAQ — Delaware

Call 5–6 contractors and specifically ask about emergency or same-day availability — many hold slots for urgent calls. Window units from a hardware store can keep one room livable while you wait. Prioritize households with elderly, infants, or medical conditions — mention this when calling, as it sometimes accelerates scheduling.

Both could be telling the truth, or one could be overselling. Ask the replacement-recommending tech to show you the specific failure (compressor, heat exchanger crack, etc.) with photos or a meter reading. A second opinion from an independent tech costs $75–$150 and can save you thousands.

Yes — a properly sealed system should never need refrigerant. Annual recharging means you have a leak somewhere. A legitimate tech should find and fix the leak, not just top it off each year. Repeated recharging without leak repair is also an EPA violation for certain refrigerants.

The installer is responsible for workmanship, and the manufacturer covers the equipment warranty (typically 5–10 years on parts). Document the problem in writing, contact the installer first. If they won't fix it, the manufacturer's warranty support line can escalate — they don't want dealers misrepresenting their equipment.

Ask for their state contractor license number and verify it on your state's contractor licensing board website (most states have a free public lookup). Also confirm they're EPA 608 certified if they're handling refrigerants. Unlicensed HVAC work can void your homeowner's insurance and cause issues when you sell.

Yes — incorrect refrigerant charge, improperly sealed ductwork, or wrong system sizing all cause efficiency loss. Ask the contractor to perform a system commissioning check (measuring airflow, temperature differential, and refrigerant pressure). A properly installed system should match the manufacturer's rated SEER efficiency.
