HVAC Tip - HVAC Preventive Maintenance: Just like a vehicle needs preventive maintenance, HVAC systems need a regular maintenance schedule. Having maintenance performed on your air conditioning and heating systems now can help you avoid costly repairs in the future. Air Conditioning and heating preventive maintenance also pays for itself by making the unit more efficient, safe, and reliable. Often, a technician can spot a ten dollar part that needs replacing now where if it is let go and not replaced, can cost you hundreds of dollars more in the future. The old phrase is true, "pay me a little now, or a lot later." I see it every day. Basic maintenance on condensers and air handling units will save you money in the long run.

That is in addition to performing preventive maintenance twice annually.
