Routine maintenance

Anybody who owns or uses a heating and air conditioning system must have heard a dozen times by now how important it is to properly maintain HVAC units in order for them to serve your need for comfort without putting a dent in your pocket. A clean, well-maintained system operates more efficiently saving homeowners up to 40% on operating cost. Just think about the operating and repair expenses of your heating and cooling system last year! Could you have saved some serious bucks if you just had clean filters in that don’t restrict air flow? Or avoid that service call where a plugged filter burnt the motor? Not to mention a humidifier which is a great product making your home more comfortable in the winter while saving you money but can force your A/C to run constantly trying to remove moisture from the air if not shut down properly at the end of the heating season. We know everyone thinks replacing a filter is no big deal - anyone can do it - but as you can see there is so much more to routine maintenance. While performing regular service a good technician – like ours –will most likely catch the first signs and find the remedy for a system malfunction before it turns into a bigger problem. Therefore manufacturers only honor their warranty if routine maintenance was regularly performed by certified technicians. Besides who can better answer your questions or diagnose a problem faster if you have issues with your HVAC system than the company that services it twice a year and keeps records off all work performed? Have us maintain your system for you or sing up for a maintenance agreement and save yourself the hassle of searching for a good HVAC company one cold winter evening when your heating system unexpectedly shuts down on you.  See our routine service checklist and you will know that your HVAC system is in good hands, and so are you. If you are an M & M HVAC customer it’s a guarantee you are never left out in the cold.



Below is a list of multiple checklists for routine service on HVAC systems.  Studies have shown that properly maintained equipment can save up to 20% in operation costs, which typically exceed the cost of annual maintenance fees and save on operational cost above the expense of the maintenance.
