LIGHT SWITCHES

DIY AC Repair Tip #1: Most everyone has noticed that there are two light switches in or around the attic area. One switch controls the light in the attic and the other one controls the power to operate your furnace. Once the switch that powers your furnace accidentally gets turned off, your thermostat may go blank or your air conditioning system may stop working.

If someone has recently been in your attic, either for a/c maintenance, installing cable, or putting away decorations, you may have your furnace light switch turned off. If you have found that your light switch in the attic is not the problem then you may need to call your air conditioning repair company, hopefully us, to resolve the problem.

THERMOSTAT SETTINGS

DIY AC Repair Tip #2: Thermostats that are set on the incorrect setting or that have low battery still account for a surprising amount of our service calls. Some simple things you can do before you call for air conditioning service are:

- - Consider upgrading to the Nest Thermostat giving much better planning and control, easy to install and maintain and change via your cellphone.

- - Check your thermostat’s battery symbol. If this symbol is flashing or indicating low battery in some way, try changing the batteries first. Note that after you change the batteries your thermostat may enter a “default” mode which loses all of your settings and you may have to reprogram your thermostat.

- - Determine what “mode” your thermostat is set on. Many times the thermostat has accidentally been turned off but the fan setting was switched from auto to on. When this happens the fan will continually run and you may think that your air conditioning system is broken.

- - If you have installed a new thermostat or had a non-HVAC professional do the installation, the wiring may be incorrect. If you believe this is the case we recommend that you contact an HVAC professional to correct the work, hopefully us.

If you have questions about thermostats or need assistance we are standing by ready to help!

PVC PIPE DRIPPING WATER

DIY AC Repair Tip #3: Did you know that when your air conditioning system runs in the cooling mode it produces water? This water is a created when the warm air in your home passes across the cold evaporator coil. The condensation created is then collected in a drain pan and drains through a small PVC pipe. If this PVC pipe becomes clogged from dirt, dust, algae build up, or rust, the drain pan overflows.

This overflow water could spill onto your sheet rock and cost you hundreds of dollars. Luckily there is an emergency drain pan that is located under your evaporator coil to help prevent this overflow water from causing damage. This emergency pan drains outside of your home, usually in front of a window that you would notice like a kitchen window or bathroom window. If you see this water dripping do not hesitate contact us to resolve the problem. Left unchecked, this drain line could back up and cause serious damage.

If you are unsure of where your emergency drain line is located, ask your HVAC technician to locate it for you during your next AC maintenance appointment. We are standing by to answer any of your questions or provide any assistance you many need.
