No Heat or No Cool?
An HVAC technician can take a no-heat or no-cool call, a strange noise, a system that won't stop running, or a straight-up replacement quote.

Hire Best Pros helps connect you with professionals who handle this type of work. We don't perform the work ourselves.
Getting a technician out
- Describe the heating or cooling problem in plain terms.
- Have the system type and thermostat reading handy.
- Most HVAC calls here start with a phone conversation.
- You decide whether to schedule anything.
What a technician sees on a typical call
- No heat or no cool, especially the first hot or cold week of the season
- A system that runs constantly but never hits the set temperature
- Short cycling, rattling, or a burning smell from the unit
- Frozen evaporator coils and refrigerant leaks
- Replacement estimates for systems past 12 to 15 years old
- Seasonal tune-ups and filter or coil cleaning
Before you call it in
Check the thermostat batteries and settings, the breaker for the unit, and whether the filter is packed with dust. That handles more calls than people expect. If all of that checks out and the system still isn't keeping up, it's time to get an HVAC technician out. A gas smell, repeated breaker trips, or a burning odor should not wait for a convenient appointment.
What speeds up the visit
- System type and rough age: furnace, heat pump, mini-split, central AC
- What the thermostat reads versus how the rooms actually feel
- Whether it's constant or comes and goes
- Any recent repairs or service on the unit

Frequently asked questions
Is it worth repairing an older system?
Depends on the age, what refrigerant it uses, how many repairs it's already had, and what this particular fix costs. Ask the technician to price the repair next to a replacement so it's a real comparison instead of a guess.
My AC is running but the house won't cool. What's going on?
There are several possible causes, including airflow restrictions, an electrical component, refrigerant issues or a frozen coil. A technician diagnoses it on site rather than over the phone.
How often should an HVAC system be serviced?
Follow the service interval in your equipment's manual or your warranty terms, since requirements vary by system. A technician can tell you what your specific equipment calls for.
