Even a minor problem with your air conditioning system could become worse and damage your Longboat Key, Florida, home if you don’t take care of it immediately. You could even need to replace your HVAC system. Have your HVAC equipment inspected by a professional at least once per year to prevent expensive, inconvenient breakdowns and save energy. Check for common signs of air conditioning trouble like an uncomfortable home, a strange smell, unusual noises, or ice on your HVAC unit before you call a professional.

An Uncomfortable Home

If your home feels warm even when your air conditioner has run for a while, you should check your air filter by holding it up to a light. If the light can’t pass through it, the filter is dirty and you should change it. A dirty air filter reduces your system’s air flow and efficiency, and it can spread pollutants around your home and lower your indoor air quality.

You should also make sure your air vents are open and keep furniture away from them. Keep leaves, grass clippings, dirt, and other debris away from your outdoor unit so it can work at peak efficiency. If your home doesn’t get more comfortable, contact a professional. You could have leaky ductwork, gaps in your insulation, a malfunctioning thermostat, an undersized unit, or another problem.

A Strange Smell

Air contaminants can cause a musty or stale smell, and it can make your allergy or asthma symptoms worse. It usually grows in areas with a high humidity, so it could mean that your air conditioner isn’t taking enough moisture out of the air. Mildew can grow inside your ductwork, on insulation, underneath carpeting or wallpaper, and more. It even can cause serious damage to your home. You can prevent this, save money, and make your indoor air feel cooler and more comfortable by using a dehumidifier.

If the odor isn’t musty or stale, and you think you smell gas or something burning, leave your home and call your local gas company or fire department immediately.

Lots of Noises

Your air conditioner should stay relatively quiet if it’s in good condition. If you hear loud pops and banging or grinding noises, your system needs repairs. Your ductwork could also be leaky or incompatible with your current HVAC system. For many homeowners, getting a new, more efficient air conditioning system is more economical than replacing ductwork. You can even choose a ductless system to save money on utility bills and maintenance.

Squealing or screeching noises could mean that your system’s blower motor needs professional adjustment or repair. You could also hear a rattling noise from a minor problem like a loose screw. If you hear buzzing sounds, scurrying, or flapping wings, contact an exterminator and then have your ductwork cleaned.

Ice on Your HVAC Unit

Ice or frost on your air conditioner or heat pump can block your airflow, raise your utility bills, and eventually cause serious, expensive damage or an inconvenient breakdown. It’s alright if you see a small amount of ice or frost in winter, but you should turn off your unit and call a professional if there’s too much or if you see ice in spring or summer. Your HVAC system could have a dirty evaporator coil, low refrigerant levels, or another problem. Don’t try to remove ice or frost yourself because you could damage your outdoor air conditioning unit.

Air conditioners and heat pumps both have a compressor with a fan that blows air across a coil. Condensation that forms on the coil can eventually freeze, reducing air flow and heat transfer rates. Many heat pumps can use a defrost cycle to remove small amounts of ice or frost, but too much can increase your utility bills and shorten your system’s life.
