Frequently Asked Questions

  1. Can I troubleshoot before calling a dealer?
    Yes. If you are having problems with your system, check the following items that apply to your situation.

    A) The total system or part of the system is not operating-- Check all breaker switches and fuses to make sure that they are not tripped or blown, make sure the thermostat is set correctly and in the proper mode selection.

    B) Weak airflow or continuous operation-- Check air filter(s) to make sure it/they are clean. Remove any obstruction at return air grille area.

    C) Ice buildup around unit piping-- Turn off system at thermostat and place towels under inside unit if possible to catch any water dripping. Thaw out coil and check items 1 & 2. If system builds up ice again, turn off system & call for service.

  2. What is the normal lifespan of a system?
    It is not uncommon to see systems getting 15 years or more of life span. Of course, several factors can make or break the operating longevity of the equipment such as providing adequate maintenance, proper installation techniques, frequency of power surges and acts of nature such as lightning strikes.

  3. Should I replace or repair my unit(s)?
    If a unit is in relatively good running condition, then making small repairs may be preferable. However, when a unit begins to cost more to repair than its actual worth, age and predicted lifespan, then replacement is recommended. Where a system has both units of the same extended age, manufacturers highly recommend replacing both units as a matched set. Better efficiencies and lower operating costs are obtained and the homeowner has the satisfaction of knowing that the system won't be breaking down any time soon, not to mention the new warranty on the units.

    Replacing only one unit on a system can be done if the age between the new and older unit isn't too great. You have to still keep in mind that the units must be compatible in capacity and efficiency range.

  4. What about warranties?
    Depending on the brand of equipment purchased, most manufacturers have a 5 year warranty on operating parts, 5 year warranty on the outside coil and compressor. The higher-end deluxe models offered by the manufacturers can even have coil and compressor warranties up to 10 years. Again, that depends on the brand chosen. A manufacturers warranty only covers against manufacturers defects in materials and factory workmanship. It does not cover damage caused by outside sources due to neglect, failure to properly maintain, or acts of nature. Labor warranties are usually covered by the installation company for 1 year from the time of installation.

    Extended warranties--separate policies that can be purchased (if offered by the manufacturer) to extend the parts, coil and compressor warranties for a certain time frame. Usually these warranties will not extend past 10 years total time from the time of installation, and do not cover damages due to neglect, lack of maintenance or acts of nature. Extended warranties for labor can also be negotiated by the companies and manufacturers. You will have to make a personal decision whether or not this may be feasible.

  5. Are yearly maintenance calls considered under warranty?
    No. A yearly maintenance call is just that-- a maintenance call. A yearly check-up is generally a pretty good idea. The service technician will check out the system and note if anything unusual may be developing and be able to prevent the situation from happening
