Your best protection for unwanted repairs and operation at the highest efficiency is to have a Conditioned Air Systems NATE certified technician complete our planned maintenance on your system. When problems do occur, we have a series of basic check points to help diagnose the problem before we arrive.

Below are some things you can do to prevent future equipment troubles and increase your system’s efficiency.

NOTE: Before undertaking any examination of your system, be sure the power is off to any piece of equipment you are examining.

One of the most important components in your heating and cooling system is the filter, and it’s the most inexpensive and easiest to replace. Especially during the peak hot and cold seasons, monthly inspections are a good rule of thumb for checking the air filter to ensure it is clean. A dirty filter can restrict airflow and cause excessive wear and tear on your equipment. Make sure to replace a dirty filter with the exact size and specifications recommended for your system.

Also, take note of any moisture or signs of mildew or mold on the filter–this can indicate a serious problem with your system as well as with the overall health of your home’s air. Call us at the first sign of water or mold and our NATE-certified technicians will diagnose and offer the best solutions to resolve this issue.

Many air supply vents have adjustments in the home which can be closed, and in turn, cause air flow issues. The return vents should also be clear of any obstructions like furniture, insulation, paintings, etc. Make sure there is a clear path for air flow for peak efficiency.

Watch for rust on metal vents which indicates potential issues with humidity control in your system. You will want to address this immediately by calling Conditioned Air Systems for a service technician to diagnose the problem and offer the best solution for your situation.

Programmable thermostats seem daunting to many homeowners, but it is well worth your time to learn how to set it according to your specific schedule. When you are at home, your thermostat can keep your home’s temperature set to your desired level of comfort.  Then, when you are away and your home is empty, you can save significantly on energy costs by programming your thermostat to run the HVAC unit less. Take the time to learn your thermostat or have one of our experienced technicians walk you through the process.

Some thermostats require batteries for proper operation. Check and replace the batteries by removing the front cover of the thermostat. A good rule of thumb is to replace your HVAC’s thermostat batteries every six months at the same time you change smoke and fire detector batteries in your home.

If the system isn’t responding to commands at the thermostat, check to see if the circuit breakers have been thrown. (Typically, there are two breakers per system.) Caution: Circuit breakers carry high voltage power and there is a shock risk. Do not attempt to remove or replace breakers unless accompanied by a trained professional.

One of the most common mistakes homeowner’s make is accidentally damaging the outside unit of their HVAC system.  This typically happens with a lawnmower or weed trimmer. Also, tall grass, leaves, walls, and fences that block airflow to the unit can strain and cause damage to your system.  It’s best to keep between 1 and 3 feet of clearance around the outdoor unit with at least 4 to 6 feet clearance overhead.

During the heating season for customers with Liquid Propane (LP) gas or oil furnaces, periodically check that your tank has fuel. We receive at least two calls every year where the tank is empty upon arrival.

If all these items are checked and the problem persists, please contact our service department at 770-534-5121.
