A central air conditioner is an effective way to quickly cool your home on those hot summer days. However, your AC system needs regular maintenance and repairs to keep it effective and efficient. If you would like to know more about AC repair and maintenance, keep reading.

Filter Replacement

Start by identifying the type of filter you have. Fiberglass filters are affordable, but they aren't the most effective option. Ideally, you should replace the filter every 30 days. If you have a pleated air filter, you can wait to replace it every 90 days. Pleated air filters have folds that increase surface area, making them more effective at catching particles.

Some filters can be washed and reused, and some, like HEPA filters, are even more effective than pleated filters at catching particles. If you use your air conditioner frequently, have pets, or have allergies, you may want to replace the filter more often than recommended. Regardless of the type of filter and frequency of replacement, you can and should do this step yourself.

AC Unit Repair and maintenance

There are some things you should leave to the professionals, such as repairs. Common signs your AC system may need repairs include:

  • The system blows warm air
  • The system blows little to no air
  • There is too much or too little humidity
  • Leaking Freon
  • Strange noises and odors

Besides repairs, you should have your system regularly maintained by a professional to prevent any future problems and extend the life of the system. During maintenance, technicians do a general inspection, clean important parts like the coils and blower, tighten screws and bolts, lubricate moving parts, and much more.

Duct Maintenance

Duct maintenance includes repairing holes/gaps, insulating the ducts, and cleaning the ducts. You can fix exposed holes and gaps with aluminum duct tape, and you can wrap insulation around exposed ducts in the attic or basement.

However, to fully inspect, repair, insulate, and clean the ducts, you'll need a professional technician who has the right tools to reach ducts hidden in walls and ceilings. If any signs of pests are noticed, you may also need a pest control expert.

AC Replacement

If it's time to replace your AC system, you'll need a professional. Typically, you want to replace the system rather than repair it if it's old. If the system is nearing the end of its life, repairs won't do much to extend the life, so you'll only be wasting money.

You may also want to replace the AC system if you need more features, such as a dehumidifier or humidifier. Other additions include zoned cooling, a UV air purification system, and much more.

If you've neglected your AC system, it's time to contact the professionals for a good cleaning and inspection. Not only will this extend the life of the system, but it reduces the risk of future expensive repairs.
