Hey Harwood, check out these air conditioning tips.

If your air conditioning is having difficulty keeping up in this heat check your return air filter(s). Dirty air filters block airflow and can cause malfunctions with your system if left unattended. Need filters? Give us a call and we can get them for you by the case which is usually a better value.

If your air conditioning is having difficulty keeping up in this heat, check your outdoor condenser coil. Cleaning the unit with a garden hose to dislodge dirt and debris can make a huge difference. Remember to remove any vegetation growing on or around the unit too! If your coil is too dirty you may need a professional. We’re here to help if you need us!

Remember to keep ducts (supply and returns) free of furniture and items. Blocked duct work can reduce air flow and efficiency.

Indoor fans can help move conditioned air around the house. During extreme heat keep ceiling fans running and consider using other types of indoor fans to move air. You may be amazed how much cooler your rooms will feel.

Make sure water is discharging from your condensate drain line. A clogged drain line can prevent your air conditioning system from removing humidity from your home. In some cases, a clogged drain line can cause water damage. We’re here to help if you need us!

Lock windows & doors, check weather-stripping around doors to keep the summer heat from entering your home. A gap as small as 1/8” can let in as much air as a 2-1/2” diameter hole in the wall.
