What a hvac technician in Milwaukee 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."

Questions to ask before you hire in WI

Are you NATE-certified, and is your company licensed and insured in this state?
For a replacement: did you run a Manual J load calculation, and can I see it in writing?
What SEER2/HSPF2 is the equipment you're quoting, and what's the AHRI match number?
Does the quote include duct sealing, thermostat, condensate pump (if needed), and permit?
What's the labor warranty, and is the manufacturer warranty registered in my name?
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.

Seasonal hvac checklist for Milwaukee homeowners

Spring

Schedule an AC tune-up before May; pros are 30–40% cheaper in shoulder season than during the first July heatwave.
Replace HVAC filters (every 30–90 days depending on type and pets).
Hose down the outdoor condenser coil and clear at least 2 feet of vegetation around it.
Test the AC by setting it to 5°F below indoor temperature; it should kick on within 30 seconds and the supply registers should blow noticeably cool air within 5 minutes.

Fall

Schedule a furnace or heat-pump tune-up before October.
Replace HVAC filters again going into heating season.
Clear leaves from around the outdoor condenser/heat pump and cover the top only (never wrap the sides).
Test CO detectors near gas-burning appliances; replace batteries.
Run the furnace for 10 minutes before the first cold snap; address any odd smells, banging, or short-cycling now.

Winter

Keep furniture and rugs at least 6 inches off supply registers and return-air grilles.
Inspect attic insulation; less than R-30 is the #1 reason heating bills run high in older homes.
Defrost outdoor heat-pump coils once every 2–3 weeks during sustained cold.
