  2. Clean filters as needed.

  3. Monitor voltage/amps on fan motor

  4. Lubricate and inspect bearing for wear.

  5. Check condition of indoor coil

  6. Flush/treat condensate drain with anti algae.

  7. Inspect condenser coil.

  8. Monitor operating pressures of refrigerant

  9. Inspect safety devices for proper operation.

  10. Inspect disconnect box for proper rating and installation.

  11. Tighten all electrical connections if needed.

  12. Test/inspect contacts for burning, pitted contacts.

  13. Inspect electrical for exposed wiring.

Five Simple Steps for a Happy and Cool Summer!

Summer is upon us! Today in Nashville TN, my A/C was on and it was not the first time this year! Just a few weeks ago we were in the mid 80's. The following easy steps we help homeowners in preventing a few problems from occurring with their A/C system this summer.

•· Inspect the filters - The first step in maintaining a well-functioning air conditioning system is to inspect the air filters. These should be changed or cleaned at least twice a year. Monthly maintenance is recommended if the system is in constant use or if the air is dusty and dirty. Replace that filter every month. The best time is when you pay your electric bill!

•· Make sure the machine is properly lubricated - Over time, friction can increase within the machine. Oil the motor and bearings twice a year. Be sure to turn off all electricity to the unit when servicing. NOTE: I would not recommend this for the typical homeowner! This job is best left for the professional HVAC contractor.

•· Inspect the fan belts - Check fan belts and pulleys for wear and proper tension. This is located in the "blower" compartment. Most newer systems do not have belts but rather a direct drive motor that is virtually maintenance free. If you do have belts that need replacing, have a professional replace worn parts.

•· Clean the outdoor condensing unit - Foreign objects and dirt can affect the performance of the machine. Brush away or hose off any insects, dirt or other items on the outdoor condensing unit.

•· Clean the drain line -Inspect the drain line to make sure there are not any problems with the termination. If algae is present, wash the affected area with chlorine. This will keep to keep the condensation water from overflowing and causing damage to your home.

If you have a window air conditioning unit, check the window and sill for decay, inspect the unit for rusting and spot paint if any rust is present.

I strongly recommend using a local company for yearly tune ups on your cooling and heating system. Once in the late summer/early fall for the heating system and then in the spring time for the A/C.

  1. Great tips on ways that homeowners can keep cool and save a few bucks at the same time. Maintenance is all too often overlooked, us inspectors see this all too often.
