Preventive Maintenance

Just like keeping your car running smooth and dependable by maintaining it, your heating and air conditioning equipment needs to be serviced to ensure proper operation. Air Conditioning and Heating Service offers an annual check-up.

When To Schedule Maintenance:

If your system heats and cools your home, perform maintenance in spring and fall. For cooling only, perform maintenance at least once a year, before the cooling season. For heating only, perform maintenance at least once a year, before the heating season.

AC&H Service provides the following maintenance

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
• Measure temperature rise and adjust airflow as needed
• Check vent system for proper operation
• 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

In addition to the annual check-up, do the following to help ensure years of trouble-free service from your equipment.

• Keep your equipment clean. This will help ensure years of trouble free service.
• Keep clutter, debris and flammable material away from the furnace and water heater.
• Replace filters regularly. A dirty filter makes your equipment less efficient and could cause equipment problems. It could also make your home less comfortable.
