The heating, ventilating, and air conditioning (HVAC) unit of your house includes an air conditioner and heat pump, or furnace, which both cools and heats the entire house. You need to maintain your air conditioner (AC) in order to save money on energy, but also to expand its lifespan. This allows you to save more money in terms of expensive early replacement.
The entire HVAC, aside from your AC, needs regular maintenance to ensure its high efficiency. Though homeowners can perform a few maintenance procedures, expert technicians like accuservheating.com who do specialised HVAC maintenance and repair are still necessary.
Here are the steps needed to keep your HVAC in tip-top shape.
Switch off the power while performing maintenance
Because of a few risks of working on the moving parts of an HVAC and around electricity, it is vital to turn off the power of your unit completely. Check for an exterior shut-off box which should be close to the unit on the exterior compressor or condenser. When indoors, switch off the power at the breaker box.
Take away the debris
On the compressor or condenser, you need to take away the fan cage. Through a wrench or screwdriver, eliminate the fasteners and hold the fan grill or cage away from the top portion of the unit. Remove the debris and leaves from the interior manually or through a dry or wet vacuum.
Clean the fins
Eliminate the outer covers and utilise the brush attachment on an efficient shop vacuum to remove external dirt. Then through a stream of water from a garden hose, clean the fins from the inside out. This is for accumulated debris and dust to be removed.
Straighten up the fins
In order to ensure efficient airflow, it is important to keep the fins straight. It is best to straighten any bent fins gradually through a commercially available straightening tool or butter knife.
Clean the unit
Upon finishing the cleaning, the fan cage needs to be replaced. Rake back debris and leaves that are outside the condenser and remove vegetation and branches that are at least two feet in every direction. This is to guarantee efficient airflow around the unit.
Clean and check the evaporator coil
On the furnace or inside the blower unit, look for the evaporator coil door. On the inside, you need to use a brush with soft bristles to remove dust from the coil. Spray it with a no-rinse coil cleaner, available commercially. The spray foams up and drips into the drain pan. The drain pan can also be cleaned using a small amount of bleach, hot water, and soap.
Clean obstructed drain
Through time, mould and algae may accumulate and possibly obstruct the drain. Thus, if the drain is not flowing well, it needs to be unplugged. Blocked drains may result in damage through flooding. If the system has a drain float, it may stop the flow of cool air.
Once seen, you need to use a dry or wet vacuum to remove the obstruction. Hold the hose of the vacuum toward the end of the drain line. Switch it on for two to three minutes then turn it off. This enables the removal of the obstruction caused by any biological matter growth.
Replace the blower filter
The HVAC filter needs replacement at least two times yearly—once before the beginning of the heating season and another before the cooling season begins. If you live in a dusty area, you may want to replace it regularly. Replace the filter daily with a new one that has a similar airflow rating.
Though these methods will aid in maintaining your HVAC, you should be aware that there are maintenance procedures that only competent HVAC technicians will be able to perform. Thus, it is best to consult them for such matters concerning heating, air conditioning, ventilation, or even the installation of solar panels and heating systems as well.
