Wouldn’t it be better to know that your heating and cooling system is well maintained and operating efficiently, rather than take your chances that it might break down? Preventative maintenance for your HVAC system is designed to give you the peace of mind that comes from knowing that your system components will come through for you when you need them. That’s why we highly recommend it for all Long Island homeowners.
Also known as precision tune-ups, preventative maintenance visits can save you up to 30 percent on your energy bills simply because they help keep your system running efficiently. Not only that, maintenance prevents repairs and breakdowns that cost homeowners thousands of dollars each year.
Preventive maintenance agreements, or PMAs, are agreements between you and your licensed contractor for scheduled inspections and maintenance of your heating, ventilation, and air conditioning system. PMAs are generally scheduled semi-annually (in spring and fall) to maintain peak efficiency, reduce utility bills, and prevent system failure. They can help extend the life of your HVAC system, as well.
During a scheduled maintenance visit, you can expect your technician to do the following:
- Check system functions, safety controls, and adjust the operating sequence where appropriate.
- Inspect electrical components and connections and repair/replace or tighten as required.
- Ensure proper airflow and change dirty air filters.
- Inspect pumps, lubricate, and check flow rates where appropriate.
- Clean and lubricate motors as required.
- Examine belts, adjust and align as required.
- Inspect, clean and balance blowers as required.
- Certain inspections are specific to your cooling system, and others to your heating system.
Cooling system maintenance:
- Clean coils, condensate pans, condensate traps, and condensate lines to prevent obstructions.
- Clean outside coil and straighten fins for efficient operation.
- Check refrigerant levels and if low, find the leak. According to many equipment manufacturers, a 10 percent refrigerant loss will result in a 20 percent decrease in system efficiency!
Heating system maintenance:
- Clean the burner assembly.
- Remove soot from fireside of burner.
- Clean and check operation of humidifier.
- Visually or with remote camera, inspect heat exchanger for cracks.
- Adjust air/fuel ratio of burner and perform combustion analysis. Instrumentation used for combustion analysis is a means of fine-tuning a burner to achieve maximum fuel efficiency and optimum firing.
Maintaining semi-annual PMAs for heat pumps is also important. For heat pump applications, winter season inspections repeat a number of the summer procedures plus several additional checks.
There are many benefits to regular scheduled maintenance for your HVAC system. According to the Consortium of Energy Efficiency (CEE), up to 50 percent more energy can be saved with proper installation, sizing, and maintenance of central air conditioning and heat pumps. Maintenance visits usually pay for themselves through these savings, making them a good investment in your home and your home comfort.
