Disclaimer

This site explains air conditioning and heating problems in general terms. It does not inspect, diagnose or repair anything.

No work is done by this site

This site does not employ technicians. When you call, you are connected with an independent local heating and cooling contractor that serves your area. That company inspects the system, gives you its price and does the work if you hire it. This site does not control, and cannot guarantee, any contractor's work, prices, schedule or availability.

General information

Every house and system is different, and only an inspection shows what yours needs. Nothing on this site is professional advice for your situation.

Cost ranges

Prices shown are typical planning ranges for common jobs. They are not quotes, local averages or price guarantees. Your figure comes from the contractor once the equipment has been looked at.

Licensing

Louisiana's State Licensing Board for Contractors (LSLBC) licenses contractors, including mechanical (HVAC) work above the board's dollar thresholds. Look the company up by name or licence number at lslbc.louisiana.gov. Anyone working on the refrigerant circuit must hold EPA Section 608 certification.

Heat and humidity

Heat and humidity together can be dangerous, especially for babies, older adults, people with health conditions and pets. If someone shows signs of heat illness, such as confusion, fainting, a very high body temperature or hot, dry skin, call 911. Don't wait for a repair before moving vulnerable people somewhere cool.

Gas and carbon monoxide

If you smell gas, leave the house straight away and call your gas utility or 911 from outside. Don't switch lights or appliances on or off. If a carbon monoxide alarm sounds, get everyone outside into fresh air and call 911.

Generators

Portable generators produce carbon monoxide. Run them outdoors only, well away from doors, windows and vents, never in a garage or under a carport. Never plug a generator into a household outlet; a transfer switch or interlock installed by a licensed electrician is the safe way to power home circuits.

Flooded equipment

Don't switch on an air conditioner, heat pump or air handler that has been in floodwater until it has been inspected.
