Preventive HVAC Maintenance

Routine HVAC Maintenance Is Good for you

Preventive HVAC Maintenance = Big Savings

If you take good care of your home’s HVAC system, you won’t have any unlikely issues with it.

Preventive HVAC maintenance includes agreements made between the homeowner and their HVAC contractor of choice. This agreement is referred to as a PMA or a preventive maintenance agreement. It is done by licensed HVAC contractors who conduct pre-arranged check-ups and preventive HVAC maintenance.

A PMA is often arranged during the spring and the fall to ensure your unit’s optimum performance and efficiency, minimize utility bills, secure a longer lifespan for your unit, and prevent premature breakdowns. At times, A PMA is also called a “planned maintenance agreement”, “preventive service agreement” or a “start and checks”. The majority of agreements serviced by contractors consist of an overall checkup of your home’s HVAC system and regular maintenance like air filter cleaning and replacement.

Energy Consumption

Your home’s biggest contributor on energy consumption is most likely the HVAC system. Refrigeration is often used among commercial applications (along with the HVAC system), so the entire building consumes so much energy. The truth is, around 1/3 of the country’s energy consumption is attributed to heating and cooling. And up to 50% of this can actually be conserved through proper installation, correct sizing of equipment, and routine maintenance of your central AC system along with heat pumps. Even if it mostly deals with commercial usage, it can also be true that homeowners can likewise save up to 50% of the total energy used by securing regular preventive HVAC maintenance.

Keep in Mind Even if you Seldom See it

Most often than not, neglect is often due to the fact that homeowners seldom see their unit. An HVAC system is often located in out-of-the-way spots in the house like the basement, rooftops, closet, or mechanical rooms, so homeowners often forget about them. People often take it for granted and only remembers it when it has a breakdown. It leads to reduced efficiency, pricey utilities, comfort issues, productivity loss, replacements sooner than expected, and even pricier repair costs.

Having your HVAC system checked at least a couple of times in a year is as essential as changing your car’s oil when it reaches 3,000 miles.

What Happens During a Scheduled PMA Visit?

* Inspection of the functions of the system, safety controls, and adjustment of the operating sequence wherever applicable.
* Inspection of all the electrical parts and connections, and the relevant repair, replacement or tightening.
* Make sure there’s a sufficient airflow and replacement of filthy air filters when necessary.
* Inspection of pumps, lubrication and checking of flow rates wherever applicable.
* Cleaning and lubricating of the relevant motors.
* Examining, adjustment and aligning of belts.
* Inspection, cleaning, and balancing of the relevant blowers.

Spring Visit (In anticipation of summer)

* Cleaning of the interior coils, condensate traps, pans, and lines to inhibit the formation of obstructions.
* Cleaning of the exterior coils and straightening of the fins to boost efficiency.
* Inspecting levels of the refrigerant. When low, look for the leak source and address it. (A lot of equipment manufacturers state that a refrigerant loss of 10% can lead to a 20% system efficiency reduction.)

Fall Visit (In anticipation of winter)

* Cleaning of the burner assembly.
* Removal of soot from the burner’s fireside.
* Cleaning and inspection of the humidifier’s operation.
* Inspection of the heat exchanger for leaks and cracks.
* Adjusting the burner’s air-to-fuel ratio and performing combustion analysis.

Reminder: When dealing with heat pumps, an inspection during winter repeats some of the procedures done during summer along with some other additional checks. Securing PMA’s twice a year for your heat pump is also essential.

The Bottom Line

Savings: You can recover the money you spend on PMA’s through lower energy costs, higher efficiency, and discounts given by the contractor. Homeowners often get discounts on various components and services done over the whole year.

Peace of Mind: Routine preventive HVAC maintenance results in fewer system failures and can extend your system’s lifespan.

Priority Service: In case you experience a system failure in the middle of summer or the dead of winter, a PMA customer is attended to first.

Continuity: Certain technicians get assigned to particular customers. Hence, a homeowner can have the same contractor who is more familiar with him or her and the equipment.
