FAQs

How often do I need to change my air filters? Once a month is a general rule of thumb for most people and situations. Use caution with leaving in filters for extended periods of time even if the filter states it is rated for a certain number of days. Thicker filters regardless of if they are thick from dust/debris build-up or thick from the amount/type of material they are built with can cause reduced airflow and possibly shorten the overall life of your HVAC system.

If I replace my outdoor unit, should I replace my indoor unit as well? In most cases, the answer is yes. There are multiple reasons why you should be replacing both pieces of equipment at the same time. Some factors are reduced efficiency, outdated equipment, higher energy consumption, no “full coverage warranty” etc.

Why should I replace my existing R-22 refrigerant unit with a new R-410A Puron unit? R-22 refrigerant and equipment are being phased out as Montreal Protocol regulations intend to reduce the impact on the ozone. The result of this phase-out makes replacing existing R-22 related parts such as compressors, evaporator coils, valves, etc. obsolete, almost impossible to find. Replacing your unit now will certainly save you extra costs and headaches in the future.

What causes an AC to freeze up? There are multiple reasons as to why an AC would be frozen and all of them require professional diagnoses and capabilities of a certified HVAC technician.

  • Dirty evaporator coil
  • Bad Thermal Expansion Valve (commonly referred to as a “TXV”)
  • Defective Blower wheel/motor
  • Improperly designed/installed ductwork (rare, but can and does happen)

Should I cover my HVAC outdoor unit in the fall and winter months? While covering your unit can prevent debris and UV rays from damaging the system, it will also cause problems if you continue to use it while it is covered up. It’s best to have it free, open, and uncovered always during usage and only cover if you will not be using the system for an extended period.

Why do I hear a popping or clicking/clacking sound when my unit comes on or goes off? If you are hearing this sound inside your home, the most common culprit is a dirty or improperly sized air filter. Check it and change it now. Another less common issue is improperly sized ductwork.

What is a zoning system? A zoning system segments your home’s HVAC ductwork into two or even more sections. This allows you to operate one HVAC system for several rooms or even floors of your home with each room/floor working independently on its own Thermostat while effectively increasing or decreasing the air temperature of that room or floor of the home. Zoning systems are made up of ductwork, in-line dampers that direct air to and from as well as Thermostats and zoning control boards.
