Changing Your Filter

How often should you replace your furnace filters?  Filters come in a verity of thicknesses, for example 1", 2" and 4".  1" filters are most common and should be changed every 3 to 4 months.  One of the most important things you can do as a home owner is check your filters and replace them as needed.  Clean filters help you furnace  to move the air throughout your home more efficiently.  

How often should I have Preventative Maintenance Performed?  

Preventative Maintenance is important for the health of your system and should be done on an annual basis to ensure your system is operating at peak performance.  

Our Air-conditioner won't turn on what can we do?

A problem with an air conditioner that won’t turn on can sometimes be resolved through a few  simple troubleshooting steps by you. Voltage power sources can be the problem, so check them all. Switches on the condenser and air handler, thermostat batteries, and circuit breakers can also be part of the problem.  In addition, make sure your thermostat is set to COOL mode, and the temperature a few degrees lower than the current room temperature. If these suggestions don’t resolve the problem, call in a professional like A TO Z HVAC we will be glad to help.
