SCHEDULE SERVICE

If you have an aging unit, we advise you to reach your local HVAC contractor in Chambersburg, PA and have them inspect your unit to determine if it’s time for a replacement. With that, these are the most common warning signs that it’s time for a new heating system upgrade:

 

  • Frequent repairs
  • Recent spikes in utility bills
  • Inconsistent temperatures in the home.

With Johnston’s Heating & Cooling, our professional heating technicians can identify if your unit has possible operation or safety problems that indicate a new system upgrade.

Our team at Johnston’s Heating & Cooling recommends that you have a professional HVAC maintenance service at least once a year. This will help improve your unit’s service life and keep them operating at an efficient level.

 

A professional HVAC technician can thoroughly clean and assess your unit’s condition and make any necessary repairs or adjustments. Maintenance service will save you from costly operation bills and ensure that your HVAC system is performing at its top condition.  

A thermostat is a tool that controls and regulates temperature in a room. This will stand as your main device in managing your HVAC system, be it an A/C unit or a furnace.

 

Whenever the temperature inside your home or office drops/rises above your desired setting, the thermostat will automatically initiate the heating/cooling process to the setting you selected for your comfort.
