  • Most Common HVAC Issues

  • Not Scheduling Routine Maintenance
    Having a professional contractor provide routine maintenance on your HVAC system is the best way to ensure it is working properly and helps prolong the lifespan of your entire system. An HVAC system is expensive, maintenance helps keep it protected!

    Dirty Filters
    Simply replacing your filter regularly is one of the best ways to ensure the life and efficiency of your furnace. Having a dirty filter restricts airflow which means your unit will have to work harder and the result is an avoidable strain on your heating system’s blower. Additionally, a dirty filter can result in your furnace overheating.

  • Pilot Light/Ignition Problems
    If you are having ignition problems, it could be for a number of reasons. Dirty pilot light, short cycling, furnace lockout, or a delayed ignition of the burners to name a few. There could also be a gas supply issue. Whatever the case, you can rely on our technicians for a swift fix.

    Mechanical Wear & Tear
    In every HVAC system, there are various mechanical components that your unit relies on. How your system performs is dependent on the condition of these mechanical parts like belts and bearings. During scheduled maintenance checks, our technicians check for worn or stretched belts and will oil your bearings, if necessary.

  • Dirty Condenser or Evaporator Coils
    Dirt and debris tend to clog the coils of your air conditioner, which is why maintenance is so important! Having a dirty condenser or evaporator coils can result in your cooling system being inefficient and the result is a shorter lifespan.

    Water Leaks
    Your air conditioner and furnace produce condensation and your drainpipes are used for an effective drainage system. If your drain lines become clogged or cracked, your furnace may begin to leak. If this happens, you can pour bleach down your drain lines to clean them. Other sources of leaks are in the collector box, heat exchanger or evaporator drain pan.
