What to Expect from Professional Geothermal System Maintenance

Your geothermal system is one of the most efficient ways to heat and cool your Delaware area home, saving you up to 70 percent on utilities associated with home comfort. But without an annual tuneup, the efficiency of your system will suffer along with your indoor air quality and your comfort level. Geothermal system maintenance by a qualified HVAC professional will extend the life of your system and ensure your geothermal system operates at optimum efficiency all summer long.

Annual geothermal system maintenance will include these key points:

• Record the water pressure and temperatures entering and exiting the system.
• Calculate the heat extraction and heat rejection of the system to measure the performance of the heat pump.
• Measure the air temperature entering and exiting the system.
• Measure the voltage and amperage of the system to ensure they fall within the manufacturer’s specified range.
• Inspect and clean the coil and air filter.
• Check the water temperature of the desuperheater
• Check the heat exchanger for blockage and clean it if needed.
• Re-pressurize the ground loop to ensure optimum cooling.
• Measure and adjust the refrigerant level.
• Tighten electrical connections.
• Lubricate moving parts.
• Inspect ducts for damage and seal leaks with mastic sealant. Between maintenance calls, there are several things you can do to ensure your geothermal system operates efficiently and keeps you comfortable for the duration of the cooling season.
• Check your air filter each month and replace it when you can no longer see through it. Your air filter keeps the system clean and improves your indoor air quality.
• Seal air leaks in your duct system and in your home to prevent cool air loss.
• Remove obstructions from your supply registers to promote optimum air flow and cooling.
