Preventative Maintenance

What is a Preventative Maintenance Agreement (PM Agreement)?


It is an agreement between, E.F. Martin Mechanical Contractors and yourself, to have planned scheduled inspections and maintenance, for your heating, ventilation and air conditioning (HVAC) system.

A PM appointment is generally scheduled semi-annually for a qualified service technician to go through your entire HVAC system preparing it for the upcoming season in a proactive approach before system failure and prior to overpaying your utility company.

There is nothing better for your heating and/or air conditioning system than preventative maintenance. This allows your system to work at peak efficiency year in and year out. A system that is maintained experiences considerably fewer breakdowns and will help extend the life of your HVAC system. This virtually eliminates the need for you to pay for costly repairs and "downtime". You'll enjoy the peace of mind in knowing that your system is saving you money on your utility bills every time it comes. on. In some instances, the energy savings are enough to pay the cost of the planned maintenance service.

My Comfort System is new why does it need to be tuned up?

Well just like a new car after one year's time it too is in need of maintenance; oil change, fluids refills or replacements, brake check etc.. The same goes for your heating and air conditioning equipment, it works hard year round to ensure that you are comfortable during those very inclimate hot and cold days. When the system work they get normal wear and tear, in addition, these systems have many electrical components that are effected by things such as; lightening storms, SCE&G power surges, power surges caused by car accidents that may have hit a telephone poll with in miles of your home. So although your equipment is "New" you should have it checked to ensure that it is working to its full capacity. It is always best to find a problem in its early stages instead of waiting until it's an emergency, which could happen on the hottest or coldest day causing you to be uncomfortable and inconvenienced.

Does the manufacturer require maintenance in order to honor the limited warranty?

Yes, most all manufacturers require at least an annual maintenance be performed by a licensed professional in order to stay with in the Manufacturers' Limited Warranty. Written on the Manufacturers' Limited Warranty page that comes with the equipment booklets states that an annual maintenance must be performed by a licensed professional or they can deny a warranty claim.
