How Long Should Your San Antonio Heat Pump Last?
A heat pump in the San Antonio area has a lifetime of around 15 years, and there are things you can do to prolong its life and maintain its energy efficiency. Heat pumps are one of the best choices for conditioning in this region, since they both heat and cool homes. In the summer, the refrigerant removes the heat from your home and in the winter, a reversing valve switches the flow. The pump extracts heat from the outside air and brings it inside via the refrigerant.
Since the pump does double-duty heating and cooling, it gets a lot of use year-round. It’s critical that you and an HVAC technician keep it maintained to extend its life. Checking and changing the air filter when it’s dirty will prolong its life, as well as keep the outdoor condenser’s coils clean. Periodically hosing off the fins and coils improves its ability to extract heat in the winter and shed it from the hot refrigerant in the summer. There should be no obstructions or vegetation within 18 inches of the pump.
When the air filters get dirty, it slows the airflow through the system and prolongs the amount of time the pump has to run, which wears it faster. Dirty outdoor coils impede heat transfer and anything too close to the condenser reduces airflow through the coil.
Professional maintenance involves adjusting the components, cleaning the electrical connections and tightening wires. The technician will measure the refrigerant, adding or removing some if necessary. He or she will also lubricate the motors, adjust the fan belt and clean the evaporator coil, if necessary. The indoor evaporator coil needs to be clean and dust-free for top efficiency.
A heat pump that doesn’t receive routine professional maintenance is likely to fail faster than one that’s well maintained. Dirt, improper refrigerant levels and reduced airflow are the most common issues that shorten the pump’s operational life.
