It’s that time of the year again!!! SPRING.
What does this mean for your Central Air Conditioning or Mini Split (Ductless) System? It’s time for a maintenance! This will ensure your system is running at its peak performance for the hot & humid days ahead. Just like we maintain our vehicles to keep them running efficiently without breakdown, we do the same for our Air Conditioning system in the spring.A system that is not properly maintained may have longer run times thus, using more electricity. The house will not cool properly on the hotter humid days, and you are more likely to have a major break down at the worst possible time (in the dog days of summer). Regular system maintenance should be done on a system that you have had for more than one year.
System maintenance should be done by an HVAC professional as it usually includes more than cleaning. During a typical maintenance the HVAC technician will be able to take measurements and steps to prolong the life of your system, or identify a potential failure by performing some, or all, of these steps depending on the type of equipment:
• Checking for loose wires. Loose connections can cause the wire to overheat and melt the coating possibly causing the system too short to ground, and even cause premature failure of components
• Testing the system capacitor, a weak capacitor can cause the compressor not to start, draw high amperage while trying to start, or burn out the motor. (A compressor replacement is a very expensive repair).
• Test and inspect compressor operation
• Check system pressures and temperatures. They will be looking to see if you have proper levels of refrigerant (the system should never be low unless there is a leak). If the tech finds evidence of leak, your options could be to repair the leak or replace the equipment. Either way, now is the time to deal with that.
• Inspect and clean the outdoor coil – HVAC Pros have special equipment and chemicals to safely clean your outdoor unit.
• Change the air filter
• Blow out the drain line to ensure the condensation will drain properly
• Inspect blower wheel for a tight fit and possible residue build up
• Inspect condenser and the evaporator coil.
• Measure amp draw on all motors to ensure proper performance to prevent a component or system failure.
While the Service Company is there you should ask about IAQ (Indoor Air Quality) products. There are some great ways to maintain good air quality in your home. Some products are specifically designed to deal with bacteria and air particulates. (The air we breathe in our homes is 40% more polluted than the air we breathe outside).
They can also propose remedies for adding humidity in the winter and dehumidifying in the summer. Now is the time for maintenance so you can stay cool all summer long!
