Top-Quality Heating & Air Conditioning Services in Jacksonville, TX

My AC is not cooling properly, what could be wrong?

There are some potential reasons your air conditioner might not be properly cooling.

  • The unit is not sized correctly for your space
  • The air filter is dirty and needs to be replaced
  • The coils inside the unit are dirty and require thorough cleaning
  • The refrigerant level is low and must be refilled

If you have ruled out these potential issues, there may be a problem with the compressor or another major component of the AC unit. In this case, it is best to call in our professional to diagnose and troubleshoot the problem.

What will your heating service include?

Our heating service will generally include a full system check, cleaning of the furnace, and replacement of the air filters. In some cases, it may involve replacing the thermostat batteries or checking for and repairing any leaks in the ductwork. Our technicians also perform a safety inspection to ensure that everything is in good working order and there are no potential fire hazards.

How often should I have my electrical system checked?

Maddox Residential and Commercial Services aims to be your one-stop shop for all your home improvement project needs in Jacksonville, TX, and surrounding areas; hence, we also offer electrical system maintenance.

We recommend having your electrical system checked at least once a year by our qualified electrician. More frequent checkups may be necessary if it is strained by regular use of high-wattage appliances or if it is located in an area with extreme weather conditions.

A visual inspection of your electrical system should also be conducted periodically to check for any damage to cords, outlets, or fixtures. If you notice any signs of wear or tear, have your system checked out as soon as possible to avoid potential hazards.
