A regular maintenance routine with an air conditioning professional will keep your unit from malfunctioning during the hottest days of the summer. An air conditioner’s filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.
In most homes, central air conditioners work together with an existing forced-air system to cool and circulate air. The air is cooled when it passes over the central air conditioner’s evaporator coil , which is the main component of the system located inside the house. The cooled air then travels through the ducts into the home while room-temperature air is pulled into the furnace’s return air duct, beginning the cycle again.
The condenser unit , which is located outside the home, is the other main component of the central air conditioning system. Both the evaporator coil and condenser are sealed systems, and require servicing by a professional technician.
Guaranteed Heating and Cooling’s preventive maintenance checks and makes adjustments to may components including; the indoor coil, the outdoor coil, the capacitors, compressor, do an all systems check on the electrical and make sure everything is tightened, check the refrigerant level, the temperatures and make sure the system is efficient and operating as it should. It is true that you can lose up to 25 percent efficiency because if the system is not operating the way it’s supposed to, such as it has dirty coil, over heated motors, lack of refrigerant effects how that system is efficient so as it goes through the year it can lose efficiency if it’s not tuned up properly.
Don’t I only need I maintenance visit only once a year, two seems like too much?
Twice a year maintenance is definitely needed in Ohio, if you have both an A/C and a furnace, because actually you have 2-different systems, parts of them in the same enclosure.
If you have a Heat Pump, its a little different because its one system and inverses the refrigeration circuit between heat and cool- though in Ohio you have a source of auxiliary heat (Mostly electric), the auxiliary heat system needs maintained.
Now, since this point is clarified, a machine normally needs to be maintained according to the manufacturer instructions, which most likely would be twice a year for most manufacturers. And let us not forget, it’s called a “Preventive Maintenance”, it’s meant to discover -as early as possible- any predictable malfunction that will catch you in the middle of a frigid night, or the heat of a rush hour.
Don’t Heat Pumps do both jobs so they only need one maintenance?
Though Heat Pumps work both as a furnace and AC by reversing the refrigeration circuit, in the winter they are generally “working harder” than in the summer and using different components like a reversing valve, auxiliary heat, or defrost system. An undiagnosed failure of a Heat Pump in the heating mode can add hundreds of dollars to your electric bill and leave you stranded in the winter when you need it most.
