When the heat quits at 2 a.m. or the AC won't kick on during a July scorcher, Hendricks & Sons Heating and Air answers — every hour, every day. Real techs, real fast, all across the Madison area.
A dead furnace in January isn't an inconvenience in Madison, WI — it's an emergency. Same for an AC that quits when the lakeshore humidity rolls in. Hendricks & Sons Heating and Air has been the call Madison families make when the thermostat stops cooperating, and we've been picking up that call day and night for over two decades.
We service, repair, and clean every major brand of heating and cooling equipment — furnaces, central air, heat pumps, ductless mini-splits, and the ductwork that feeds them all. No call centers, no runaround. A Wisconsin-trained tech rolls up, diagnoses it straight, and tells you the price before any wrench turns.
Dusty registers, musty smells, or rooms that never quite cool down? Your ductwork could be packed with years of pollen, pet hair, construction debris, and mold spores — and every time the blower kicks on, that mess gets pushed back into the air your family breathes. Our duct cleaning service agitates and vacuums every supply and return run in your Madison home with high-volume HEPA equipment, improving airflow, lowering utility bills, and giving allergy sufferers real relief. We document before-and-after conditions so you see exactly what came out.
Call to schedule duct cleaningHeat pumps are workhorses in the Madison climate — efficient in shoulder seasons, critical on bitter nights when backup heat strips kick in. If yours is short-cycling, blowing cold in heating mode, icing up in summer, or tripping the breaker, our techs diagnose the real failure fast: bad reversing valves, low refrigerant charge, failed capacitors, defrost board faults, or compressor issues. We stock common parts on every truck and carry the certifications to handle refrigerant legally and safely. Most heat pump repairs in Madison are done same visit.
Call for heat pump repairWhen the humidity spikes and your AC blows warm — or worse, won't start at all — every minute counts. Hendricks & Sons Heating and Air answers 24/7 because we know how fast a Wisconsin summer afternoon turns a closed-up home into an oven. We troubleshoot frozen coils, clogged condensate drains, failed contactors, low Freon, fan motor failures, and compressor lockups. We'll tell you straight whether a repair gets you another five seasons or whether replacement makes more sense — no pressure, just honest math from a tech who lives in the same town you do.
Call for AC repairA furnace that won't fire on a single-digit January night isn't just cold — it's a pipe-freezing countdown. Our furnace repair techs roll to Madison homes around the clock for no-heat calls, addressing cracked heat exchangers, bad igniters, flame sensor fouling, tripped pressure switches, blower motor failures, and faulty thermostats on gas, electric, and oil units. We carry the diagnostic gear and common parts to get heat back on during the first visit in the vast majority of calls. When it's freezing inside, call us — we treat it like the emergency it is.

Open 24 hours, 7 days a week. There's no answering service, no "we'll call you back in the morning." When your furnace quits on Christmas Eve, a real person picks up — and a real tech rolls out.
Since 2005, we've repaired thousands of furnaces, ACs, and heat pumps across Madison and the surrounding towns. We know the equipment, the housing stock, and the cold-weather failures that come with both.

We live and work where you do. That means short drive times, fast emergency response, and a reputation we actually have to keep — you'll see us at the hardware store next week.
