Signs You Need Air Conditioning Repair
Properly maintaining your air conditioning unit is one of the best ways to reduce the frequency of air conditioning repairs and/or limit the severity of the repairs that are needed. However, there are times when your unit may need a repair even if the unit is properly maintained. Knowing what the signs are that indicate a repair is needed helps you to know when to call in an air conditioning company.
One of the tell-tale signs that indicates that air conditioning repairs are needed is an air conditioning unit that only blows hot air or one that blows no air at all. Other signs that are indicative of air conditioning unit problems include an air conditioning unit that is making strange noises, an air conditioning unit that is blowing smelly air into your home, an air conditioning unit that is short cycling or rapid cycling, and your energy bill increasing drastically while running your air conditioning unit. Most people are familiar with what their unit sounds like, smells like and how long the unit cycles. If something seems off, it is best to have a professional inspect your unit.
