Is it an emergency?
What can wait, and what cannot
General guidance for homeowners. If you smell gas or a carbon monoxide alarm sounds, leave first and call 911 or your gas utility from outside.
Gas, smoke or a CO alarm
- A carbon monoxide alarm is sounding, or anyone has a headache, dizziness or nausea that eases when they step outside
- You smell gas – often like rotten eggs – near a furnace, water heater or stove
- Smoke, or a hot burning smell, from a furnace or other equipment
First: get everyone, pets included, out into fresh air. Do not switch lights or appliances on or off. From outside, call 911 or your gas utility’s emergency number. Do not go back in until you are told it is safe, then have the equipment checked before you use it again.
No heat or no cooling, and it matters
- No heat in freezing weather
- No cooling in dangerous heat, especially with babies, older adults or anyone unwell at home
- Water leaking from a furnace or air handler onto a ceiling or floor
- A breaker that trips again every time the equipment starts
First: turn the equipment off at the thermostat if it is leaking or tripping the breaker, and call a company that says it takes emergency calls. If it is dangerously cold or hot, go somewhere safe until it is fixed.
It can wait for a quote
- A yearly tune-up before heating or cooling season
- An older system that still works, and you want to plan the replacement
- Adding a heat pump or a mini-split
- Hot or cold rooms, or ductwork changes
Do: get two or three written quotes. How to compare them.
The full guide: what to check first, an iced-up AC, a furnace that will not start, and what to tell the company.
Maintenance tips
Look after your system, season by season
A few minutes a month and one professional visit a year prevent most breakdowns. Plain-English guides, sourced from the U.S. Department of Energy, ENERGY STAR, the EPA and the CPSC.
Heating season: furnace smells like burning, heat pump blowing cold air, preventing frozen pipes and space heater safety.

The directory
98 metro areas, listed A to Z
2,079 local HVAC companies within about 25 miles of US cities (35 in smaller metro areas), each with its phone number, base location and the services it offers.
Every one of the 50 states has HVAC companies listed, and a page on how it licenses HVAC work, with the official lookup where one exists.
Before you hire
Eight questions to ask every HVAC company
Ask each company the same questions and the answers become comparable. Write the answers down.
- Are you licensed for HVAC work in this state or city, and what is the license number?
- Are you insured, and can you send the certificate?
- Are your technicians certified under EPA Section 608 to handle refrigerant?
- Is the price a written, itemized estimate – equipment make and model, labor, permit, ductwork changes and haul-away?
- Will you size the new equipment with a load calculation, rather than just matching the old unit?
- Is there a trip or diagnostic fee, is it credited if I hire you, and what do you charge for nights and weekends?
- Who pulls the permit, and will your own employees do the work, or a subcontractor?
- What is the warranty on labor and on the equipment, and who registers the equipment warranty?

Quick answers
About Heating and Cooling
How are HVAC companies chosen for this directory?
A company is listed when its own website shows it does heating or air-conditioning work, a phone number and a base location within about 25 miles of the city (35 miles in smaller metro areas). Lead-generation sites and call centers that pose as local HVAC companies are left out. Listings are free and shown A to Z. How we list.
Do you check HVAC licenses?
Not yet. Where a company prints a license number on its own website, the listing shows it. Each state page explains how that state licenses HVAC work and links to the official lookup, so you can check before you hire.
Is a company listed here recommended by you?
No. A listing means the business passed our listing rules, not that we vouch for its work. The order is alphabetical, and paid placements are labeled.
What should I do first if my heat or AC stops?
If you smell gas or a carbon monoxide alarm sounds, leave first and call 911 or your gas utility from outside. Otherwise check the thermostat, the air filter and the breaker, then call a company. The guide has the details.
Is it free to use?
Yes. Searching and requesting a company are free for homeowners and businesses. Companies are listed free; some pay for labeled placements.
