What a hvac technician serving 21233 actually does

A residential HVAC technician services, repairs, and installs forced-air furnaces, central AC, heat pumps, mini-splits, and ductwork. A diagnostic visit typically includes static-pressure measurement, refrigerant pressure (for cooling systems), temperature differential between supply and return, electrical-component testing (capacitor microfarad, contactor pull-in, transformer voltage), and ignition or burner inspection on heating equipment. Installations require Manual J / Manual D / Manual S calculations to size the equipment correctly — beware any installer who skips these and recommends "the same size you have now."

Six questions before you hire

  1. Are you NATE-certified, and is your company licensed and insured in this state?
  2. For a replacement: did you run a Manual J load calculation, and can I see it in writing?
  3. What SEER2/HSPF2 is the equipment you're quoting, and what's the AHRI match number?
  4. Does the quote include duct sealing, thermostat, condensate pump (if needed), and permit?
  5. What's the labor warranty, and is the manufacturer warranty registered in my name?
  6. Will you provide commissioning data (subcooling/superheat, static pressure) at completion?
"Same-size replacement" without a load calc, refrigerant-only quotes that don't address the leak, and any installer who pushes the largest unit without explaining why.
