HVAC repair, routed to a licensed local contractor
HVAC repair help is one call away, 24/7. The call routes to a licensed local contractor in your area — for an AC, furnace, heat pump, boiler, or mini split. The $75–$200 diagnostic fee is usually credited toward the work.
Cooling, heating, heat pumps, boilers, and ductless — one number routes them all.
The badge on the cabinet changes the parts, not who answers your call.
You approve the price before any part is replaced — no surprises on the bill.
- STEP 01
Call, no cost
One call routes to a licensed local contractor covering your area. Tell them what the system is doing.
- STEP 02
Identify the system
AC, furnace, heat pump, boiler, or mini split — the contractor confirms which system and books the right technician.
- STEP 03
On-site diagnosis
The tech finds the failed part and quotes the repair before touching anything. The diagnostic fee is usually credited.
- STEP 04
Repaired & tested
The fix is made, the system is tested, and you settle with the contractor directly.

Start by naming the system
Identify the system first and the diagnosis follows: vents blowing air mean a furnace or heat pump, radiators mean a boiler, and a head on the wall means a mini split. Each card links to that system's repair page.
Air conditioning
The tell: It runs, but the air is warm.
Common faults: Capacitor · refrigerant · frozen coil · compressor.
Furnace
The tell: It lights, then dies seconds later.
Common faults: Igniter · flame sensor · blower · heat exchanger.
Heat pump
The tell: Cold air on HEAT, or a huge winter bill.
Common faults: Reversing valve · defrost control · backup heat.
Mini split
The tell: Water down the wall, or a musty smell.
Common faults: Blink codes · condensate drain · inverter board.
Boiler
The tell: Boiler hot, radiators cold.
Common faults: Pressure loss · circulator pump · expansion tank.
Five checks before you call
Whatever the system, five free checks end a real share of service calls before they're booked: the thermostat, the breaker (once), the filter, the cutoff switch and door, and the outdoor unit.
The thermostat
Confirm the mode and setpoint are actually calling, and swap the batteries. A dead cell blanks the screen and the whole system with it — and ends a genuine share of no-heat and no-cool calls.
The breaker, once
Find the system's breaker and, if it has tripped, reset it a single time; check the outdoor disconnect too. A breaker that trips again is reporting an electrical fault — stop there.
The filter
Pull it and hold it to a light. If light doesn't pass through, it isn't a filter any more. Airflow starvation ices AC coils and trips furnace limit switches — the least expensive fix in the building.
The cutoff switch
Furnaces and air handlers have a light-switch-style cutoff nearby, and a door safety switch that must be fully seated. Someone flipped it, or the panel was left a quarter-inch proud after a filter change.
The outdoor unit
Clear leaves, snow, and shrubbery, and give it two to three feet of breathing room. A condenser that can't shed heat won't perform however healthy it is.
Filters, thermostat batteries, one breaker reset, and clearing the outdoor unit are yours. Refrigerant handling legally requires EPA-608 certification, and gas-side work — burners, gas valves, heat exchangers — belongs to a licensed technician. These are safety boundaries, not skill boundaries.
What to have ready
Five details get you to the right technician faster — and often shorten the diagnosis once they arrive.
- The make and model — usually on a label inside the cabinet door or on the outdoor unit
- What the symptom actually is: runs but no heat, won't start, water on the floor, a noise
- When it started, and what changed just before — a power cut, a storm, a filter or thermostat swap
- Any error code — a furnace board and a mini-split head both blink their own fault; count the blinks
- Whether you've already reset the breaker, and whether it held
What a service call actually is
The diagnostic or trip fee runs $75–$200, and it pays for the technician's travel and the time to find the fault — not for parts. Most contractors credit it toward the repair if you approve the work on the same visit.
What each common repair runs, part by part, is on HVAC repair cost; what the diagnostic fee buys is on service-call cost; and the age bands for repair-vs-replace are on repair or replace.
Is it an emergency?
No heat in a hard freeze risks frozen pipes; no cooling in a heat advisory is a health risk for older adults, infants, and pets. And if you smell gas or a carbon-monoxide alarm sounds, leave the home and call from outside. We route after-hours calls to the contractor with the soonest slot.
Where we route calls

Questions homeowners ask first
What does an HVAC service call cost, and does it come off the repair?
The diagnostic or trip fee typically runs $75 to $200, and it pays for the technician's travel and the time to identify the fault rather than for any parts. Many contractors credit it toward the repair if you approve the work on the same visit, but that is a policy rather than a rule — ask when you book. The details are on our HVAC service call cost page.
What should I check before calling for HVAC repair?
Five things, and all of them are free: the thermostat mode and batteries, the breaker (reset it once, and only once), the air filter, the nearby cutoff switch and the furnace door, and whether the outdoor unit is buried in leaves, snow or ice. Together these end a real share of service calls before they are booked.
Is HVAC repair worth it on an old system?
Weigh the repair against a replacement. Under roughly a third of a new system's price, repair generally wins. Over half — or a major component like a compressor or a heat exchanger failing on a system past two-thirds of its expected life — leans toward replacement. The framework lives on our repair or replace page.
What can I legally repair myself?
Filters, thermostat batteries, resetting a breaker once, and clearing debris from an outdoor unit are all yours. Refrigerant handling legally requires EPA Section 608 certification. Gas-side work on a furnace or boiler — burners, gas valves, heat exchangers — belongs to a licensed technician. These are safety boundaries, not skill boundaries.
Who repairs my brand?
Routed contractors service every major brand. The badge on the cabinet changes which parts a repair needs; it does not change who answers your call.
Can someone come out the same day?
Often, though it is never guaranteed. Same-day availability depends on provider participation and on demand in your market, and demand peaks precisely when the weather is worst. We route your call to the contractor with the soonest available slot.
How do I know which repair page to read?
Identify the system first. Vents blowing air mean a furnace or a heat pump; radiators mean a boiler; a head on the wall means a mini split. If the outdoor unit runs in January, it is a heat pump rather than an air conditioner. Our heating guide walks through the identification in about thirty seconds.
