Philadelphia residents will need an efficient and highly functioning HVAC system in their homes to keep themselves comfortable through the harsh days of winter and summer every year. Proper heating and cooling of homes can only be ensured when the various components of the HVAC system are maintained to keep them in great condition. In brief, these HVAC parts need particular attention:

The Thermostat

Your HVAC system’s thermostat is what controls the temperature indoors. When you have problems with it, you may end up with rooms that aren’t as warm or as cold as they need to be. Though thermostats are accessible enough, it’s not that easy to detect that anything is wrong with them.
Have an HVAC professional look over your thermostat as part of the system maintenance. Usually, the malfunction that may be due to broken wiring, or some other, can easily be repaired.

The Evaporator and Condensing Coils

When you’re talking about the cooling of your HVAC system, the evaporator and the condensing coil are the heart of it. Warm air passes through these two components and their temperatures are lowered. For these parts to function well, there has to be a minimum level of refrigerant in the system. Having this inspected during every maintenance check, ensures that air in the unit will be cooled properly at the desired level. If there are leaks, you’ll need to have them plugged up and the refrigerant replaced. You’ll need to check on the accumulated dirt, as well; when the insulated coils are dirty, it makes it harder for the unit to cool the air that passes through it. This raises the energy costs with the system overworking to cool a room.

The Furnace

Your furnace is where the warmth in your home comes from; cool air enters the unit and is heated and distributed throughout your home via ducts and vents. Heating an entire home can cause a lot of wear-and-tear on the furnace, which is why an old heater needs service from skilled experts like DN HVAC Services to ensure that its parts are always in good working order. A malfunction in the blower, gas line, or other parts can mean trouble down the line. Have an HVAC technician check your furnace annually for the regular tasks of cleaning, tune-ups, and repairs, if needed.

Professional Help

The technical part of maintaining your HVAC system is best left to the professionals. You want to keep the system up to standards; when it’s bitter cold outside, you don’t want to be kept guessing if your furnace is going to hold forth. Stay safe and comfortable with the help of heating and cooling professionals.
