Preventive maintenance = $avings!

Preventive maintenance agreements (PMAs) are agreements between you and ACentral for scheduled inspections and maintenance of your heating and air conditioning system.
PMAs are generally scheduled semi-annually to maintain peak efficiency, prevent utility overpayment, and avert system failures through predictive maintenance that can help extend the life of your HAC system. Sometimes PMAs are also referred to as planned maintenance agreements, start and checks, or preventative service agreements. PMAs usually consist of fall and spring scheduled sessions for an ACentral's service technician to go through your entire HAC system preparing it for the upcoming season in a proactive approach before system failure and prior to overpaying your utility company.

Energy Consumption

The HVAC system is most likely the single biggest use of energy in your home. In commercial applications where refrigeration is applied (combined with the HVAC systems), huge amounts of energy are used in the building. In fact, over 1/3 rd of the energy used in the United States is used to heat and cool buildings.
According to the Consortium of Energy Efficiency (CEE) up to 50% more energy can be saved with proper installation, sizing, and maintenance of commercial central air conditioning and heat pumps. "Although the CEE study did not measure residential systems, a compelling case can be made that proper maintenance can save homeowners up to 50% as well,"

Out of sight, Not out of Mind

The old but true cliché "out of sight, out of mind" is often the reason for neglected maintenance guidelines for your HVAC system. HVAC systems are usually installed where they aren't seen, such as in a section of the basement, a closet, on rooftops, or in mechanical rooms, making them easy to ignore. The systems are simply taken for granted, until they fail. Decreased efficiency, utility overpayment, discomfort, loss of productivity, eventual premature replacement, and higher repair costs are the result.
Just because your HVAC system is out of sight, does not mean it can be neglected. Getting your HVAC system checked twice annually is just as important as changing the oil in your car every 3,000 miles!

What should you expect ACentral's service technician to do during a PMA visit?

Suggested Pre-Season Preventive Maintenance Check List
Outdoor Unit/ Air Conditioner or Heat Pump: Clean dirt, leaves and debris from cabinet
Inspect coil and cabinet; clean as needed
Inspect fan motor and fan blades for wear and damage; on older models lubricate as needed
Inspect control box, associated controls/accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories. All control box and electrical parts should be checked for wear or damage.
Inspect compressor and associate tubing for damage
Wash outside of cabinet when and where possible
Indoor Unit: Furnace or Air Handler
Inspect and clean blower assembly (includes blower housing, blower wheel and motor)
On older models lubricate motor and inspect and replace fan belt if needed
Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed
Inspect for gas leaks in gas furnaces
Inspect burner assembly - clean and adjust as needed
Inspect ignition system and safety controls - clean and adjust as needed
Inspect heat exchanger or heating elements
Inspect flue system
Inspect control box, associated controls, wiring and connections
Clean or replace air filters (You'll be charged for material)
Inspect conditioned air flow system - check for leaks
While System is Operating
Monitor system starting characteristics and capabilities
Listen for abnormal noise
Search for source of unusual odors
Monitor air conditioning and heat pump systems for correct refrigerant charge
Measure outdoor dry bulb temperature
Measure indoor dry and wet bulb temperature
Measure high and low side system pressures
Monitor gas furnace for correct line and manifold gas pressure - make adjustments as needed
Monitor system for correct line and load volts/amps
Monitor system operation per manufacturer's specifications
Provide system operation report and recommend repairs or replacement as necessary (You'll be charged for labor and material)
Check system functions, safety controls, and adjust the operating sequence where appropriate.

What's your bottom line?

Savings: PMAs typically more than pay for themselves through higher efficiency, less utility overpayment, and contractor discounts. PMA customers typically receive a 5% discount on all parts and 10% discount on labor performed during the entire year.
Peace of Mind: Predictive maintenance will mean fewer system failures and a longer life for your HVAC equipment.
Priority Service: Should a system failure occur during the heat of the summer or the cold of the winter, customers with PMAs generally receive priority service.
Continuity: ACentral is often able to assign technicians to the specific customers. That way, you get to see and know the same service technician, and he or she becomes more familiar with you and your equipment.

The cost of Preventive maintenance agreements (PMAs) are as follow;

Commercial:
$35.00/Tons/ year for first up to 5 tons. Min. $165.00
$30.00/Tons/year for second or more than 5.
Residential:
$30.00/Tons/year. Min. $150.00
