Most homeowners wonder why they cannot just complete a tune-up themselves. The reason behind is that thorough tune-up needs skills, knowledge, and tools that only experienced HVAC technicians may deliver. Here is what you can expect once you call in the experts to perform yearly HVAC system maintenance:
Lubricate Every Moving Part – If there’s no lubrication, it can cause high amount of friction in the system. It may also cause it to break down and overheat. Adding lubrication may help every moving part move smoothly against each other, reducing electricity use and reducing energy bills.
Tighten Electrical Connections – You have to take note that loose connections are harmful and may cause improper operation, which shortens the lifespan of the equipment. Technicians also measure current and voltage on equipment motors.
Check the Thermostat – Technicians ensure that the thermostat is correctly calibrated to ensure comfort in each season. If you do not have an installed programmable thermostat, professionals might recommend one and install it for you.
Inspect Your System’s Condensate Drain – Condensing furnaces and cooling equipment produce condensate when they run. Under the normal conditions, condensate collects in the pan and drains away to the outside. Nevertheless, over time algae or sludge may form in the drain pipe and make a blockage. During high usage time, drain pan might overflow and could cause water damage to your home or equipment. Professionals check the condensate drain to ensure that it is draining properly. If necessary, they also clean it.
Adjust and Clean the Blower – Problems with blower may reduce the efficiency of the equipment by up to fifteen percent. Adjustments ensure ample home comfort and proper airflow.
Check the System Controls – The shut-off sequence, operation, and start cycle must occur in a certain fashion. Technicians check the control to ensure everything is operating properly and safely.
Clean Evaporator and Condenser Coils – The soiled coils slowly reduce efficiency and make the system operate longer. Cleaning coils yearly is an essential part of maintaining the capacity of the AC, ensuring low energy bills and prolonging the system’s life.
Check the Fuel Line Connections – Poor oil or gas connections are fire hazard. These may also cause health issues if the fumes can escape into your home. Tightening connections ensures safe operation.
Check Refrigerant Charge – If an air conditioner unit was highly charged at an installation, you might be paying more than necessary to cool your home. Undercharged system can develop once the system has leaks. Professionals check for such circumstances, fixes any leaks that are present, and recharges system if necessary.
Inspect Burner Combustion, Gas Pressure, and Heat Exchanger – Dirty burner, incorrect pressure or cracked heat exchanger may result in inappropriate burner operation. Such circumstances may also cause inefficient and unsafe operation. Adjusting pressure and cleaning the burner are viable options to enhance operation and reduce your heating bills, yet once there’s cracked heat exchanger, it is likely you will have to buy a new furnace.
An essential part of HVAC maintenance is hiring professionals with the right experience and skills for the job.
