An HVAC system is very important when it comes to making your home a comfortable place all year long but you cannot expect it to be trouble free unless you take good care of it. Of course you can repair the HVAC unit when it breaks, but you will have to pay more for the urgency of the service and also live without AC or heat for a number of days.
With proper maintenance of the HVAC unit, you will lower the risk of it failing at times when you need it most, for instance during a cold winter night. You will also save money that you could have used on big repairs, for instance purchasing expensive parts to replace those that have failed. The overall life of the unit will also be prolonged and as a result the need for replacement will be delayed. Maintenance of the HVAC unit ensures that it is working efficiently, so you are going to save money on long term energy bills.
During HVAC maintenance, a thorough inspection will be done on it depending on the season. The inspection and cleaning of the condenser as well as evaporator coil should be done as necessary. Though the coils do not require regular cleaning, with time, dust and debris accumulates. For them to function efficiently, the dust and debris has to be removed.
The amperage draw of the compressor as well as the blower motor should be checked from time to time to make sure that all electrical connections are operating as expected. If there is a faulty connection, the operation of the HVAC unit may be unsafe and the lifespan of some components may be reduced. It is also important to oil parts of the unit that are under a lot of friction, for instance fan motors. When friction is reduced, the amount of energy needed to move a specific part is also reduced.
It is important to check the operation pressure as well as temperature of the unit to make sure that they are according to recommendations from manufacturers. If you notice that the unit is overheating, it could be due to faulty wiring or other internal issues. The coolant level also needs to be checked. If there are coolant leaks, they should be fixed and refilled to the right levels. With continued use of the HVAC system over the years, it is normal for it to lose refrigerant charge. But if your unit requires a refill every season, you will have a major leak that needs fixing before restoring its charge.
Another maintenance of great importance to the HVAC unit is to check and calibrate the thermostat to make sure that it communicates the right temperature settings to the air conditioner. To save more energy bills, you can decide to upgrade to a programmable thermostat.
You can do simple maintenance on the HVAC unit on your own, but for things you cannot understand you should be sure to call professional service. Performing seasonal maintenance on the unit will enable it to serve you many more years to come.
