HVAC Repair
When the furnace won't keep up or the AC blows warm on the hottest day of the year, you need a competent diagnosis more than anything else — the repair itself is often straightforward once the real cause is found.
Describe what your system is doing and we'll match you with screened, independent HVAC technicians near you. They diagnose on site, explain what failed and why, and give you their own written quote. An honest technician will also tell you when a repair no longer makes sense.
Signs you may need this
- The system runs constantly but the house never reaches the set temperature
- Some rooms are fine while others are noticeably hot or cold
- New noises — banging, screeching, rumbling — or burning smells at startup
- Utility bills climbing without a change in usage or rates
- The system trips the breaker, short-cycles, or won't start at all
Questions worth having answers for
These are the questions our request form — and any good contractor — will ask. “I don't know” is always an acceptable answer.
- What type of system is it (furnace, central AC, heat pump, boiler)?
- What symptom are you seeing, and when did it start?
- Is the system completely down, or limping along?
- Roughly how old is the equipment?
- Is anyone in the home vulnerable to heat or cold while it's down?

HVAC Repair questions, answered plainly
Why is my AC running but not cooling?
Common causes range from a clogged filter or tripped condenser breaker to low refrigerant from a leak or a failed capacitor. Some are cheap fixes; some aren't. Check the filter and the outdoor unit's breaker first — beyond that, a proper diagnosis is worth more than guessing, because repeatedly topping off refrigerant without fixing a leak wastes money.
Should I repair an old furnace or replace it?
The honest answer depends on the failure and the equipment's age and condition — a blower motor on a mid-life furnace is a different decision than a cracked heat exchanger on an old one. Ask the technician for the repair cost, the remaining life expectancy, and what a replacement would run. Our repair-or-replace guide lists the questions worth asking.
Who does the actual repair work?
An independent, screened local contractor. HVACandRoof is a matching marketplace — we don't perform repairs, and the technician's diagnosis, quote and workmanship are their own. We screen for credentials like licensing and insurance where required, and we may earn a disclosed fee from contractors for qualified introductions.
What should I do while I wait for a technician?
If you smell gas or burning, shut the system off and follow your utility's safety guidance first. Otherwise: check the thermostat batteries, the air filter, and the breaker. Note any error codes or unusual sounds — details like these help the matched technician arrive prepared.
