Should I Purchase a Maintenance Plan For My Swimming Pool Heat Pump?
We are often asked this question. The answer is yes in all cases, and an emphatic yes! in many cases. Let’s see why.
The simplest explanation why a maintenance plan makes sense is to consider your home air conditioning (A/C) system. Assuming you have an annual maintenance plan on your unit, you already know the value of having regular annual service performed on your system. If you do not have a maintenance plan, perhaps you need a new service company that is interested in helping you protect your investment.
With a home air conditioning system, one of the key reasons for annual service to clean heat exchanger coilsyou know the ones with the aluminum fins on the outside of your A/C unit? Those aluminum fins have copper tubes routed through them and Freon, or other refrigerant, travels through those copper tubes while air is pulled across the aluminum fins by a large fan. The refrigerant absorbs the heat from the air, cooling it, before the air circulates throughout your home. For efficient heat transfer to take place, a large volume of air must be drawn across the aluminum fins. In a typical system, a home air conditioning system moves around 300 to 400 cfm of air (cubic feet per minute) per ton of air conditioning capacity.
A heat pump pool heater (HPPH) system works in reverse, you might say. It takes heat from the air and transfers it to the pool water, but it moves roughly twice the amount of air as an A/C system.
Both A/C and HPPH units create condensation during the heat removal process. The resulting water content on the surface of the aluminum fins, mixed with air born particles (dust, pollen, etc.) that are naturally in the air, can create a film or coating on the aluminum fins that inhibit the efficient transfer of heat energy. Your air conditioning system uses filters to help minimize that problem. That is why you always hear from your A/Ccontractor to keep those filters clean.
Neglecting to change your system filters can not only result in costly repairs down the road, but as your coils become increasingly clogged with dirt and crud, your system will function less efficiently, costing you more money to operate.
During an annual maintenance visit, the tech will clean the coils and check other parts of the system to make sure it is operating efficiently. Planned maintenance doesnt guarantee that your unit will not require other service at some point, but it does ensure that your unit operates at its best possible efficiency. It may also detect other minor problems before they become major problems that will be costly to repair.
The emphatic yes reference at the beginning of this blog relates to equipment installed at or near the coastline, where the air contains not only the normal dust, pollen, etc., but also trace amounts of salt. The salt acts like an acid on the aluminum fins of your heat exchanger coil and can rapidly dissolve the aluminum. Left unchecked and un-cleansed, this condition will lead to very costly repairs.
Purchasing a maintenance plan for your swimming pool heat pump is one decision that will save you money both now and down the road. Why not take advantage of the opportunity to protect your system before it’s too late?
