Comfort appliances come in all types, but the most common of them are portable units that fit into windows and HVAC (heating, ventilation, and air conditioning) systems. Unfortunately, the use of portable air conditioners is not too efficient, and they rarely cool the building very well. The HVAC system, on the other hand, is a great way to cool a whole house to a consistent temperature. To keep the appliance operating at its best, it is a good idea to have Residential HVAC Service in St. Louis MO performed at least once every year.
Most manufacturers recommend that the HVAC system is serviced by a qualified technician sometime in the spring before it is put under a load. For an appliance that has been idle for months, it is a good idea to have this service done before the system is cranked up. There are a couple of reasons for this including the need to ensure the refrigerant is properly charged and that the evaporator coil is completely cleaned. Failure to have this service performed may not cause the unit to fail immediately, but it does create problems that can result in expensive repairs at a later date.
For example, without Residential Hvac Service in St. Louis MO, the evaporator coil can build up a clog that could freeze. Ice buildup on the coil can cause a rupture and this will quickly force the appliance to fail. A break in the coil allows the refrigerant to leak out, and without this vital chemical, the appliance cannot create cold air.
Service should include testing the system for signs of electrical faults. This includes external components such as the thermostat. Most new appliances use a digital system to control thermostat settings, but there are still a few that use mechanical switches. These switches can fail, or worse, make it difficult for the appliance to switch on or off as required. Other sensors that may need testing include the control switches in the air handlers. These switches determine when the blower should engage and when the furnace is done generating heat. Learn more about HVAC service from the experts at Courtney’s Heating & Cooling.
