The Do-It-Yourself Guide to HVAC Cleaning and Maintenance
Posted on: January 13, 2015 | by: Will Housh
With average costs anywhere between $150 and $425, having your HVAC system professionally cleaned may not be in the budget. While you cannot solve every issue with preventative maintenance, here are seven do-it-yourself tips you need to know to keep your system healthy:
Check and replace your air filters often.
Set a reminder each month to check your air filter and replace it if it is dirty or clogged. While the general rule is to change your filter every 30 to 90 days, they may need to be replaced more often if you have pets or open your windows often.
Another thing to consider is purchasing a new high-efficiency pleated air filter. The folds in these filters trap more small particles than traditional filters, keeping your system clean and your family healthy.
Keep your AC and heating systems free of debris.
If you have an outdoor unit, it is important to keep the system free of debris. Check your unit every week or so for leaves, pollen, dirt, sticks or other debris. Clear the debris from the top and sides of the system using gloves and, if necessary, a hose. This allows for maximum airflow to the fan and increases your unit’s efficiency and lifespan.
In order to ensure the cleanest system possible, try to remove anything that blocks air flow to the system, leaving about two feet of space around the unit.
Clean your registers
Try to keep your registers and ducts clean of dust and debris. Be sure to wipe down your registers as often as possible to keep dust and debris out of your system.
Give your humidifier a vacation.
In order to give your system a rest in the summer, turn off your furnace humidifier’s water supply. When the cooler months approach, replace the water panel (also know as humidifier pad), set the relative humidity between 35 and 45 percent, and turn the water supply to the furnace humidifier back on.
Listen for unusual noises.
One more passive things you can do is to keep an ear open for odd noises when your system is running. Often times, noises in your system are created by register blockages, debris in the vents, or loose bolts on the furnace or registers. If you hear any odd noises, try to locate the source. If you can’t find the source, check out this list of common HVAC system noises, what they mean and how to fix them. If this does not solve the problem, go to tip seven.
Use fans to give your system a break.
Another passive way to keep your system healthy is to use fans when possible to give your system a break.
On hot summer days, use ceiling fans and portable fans to circulate air through the house and help your HVAC system bring the temperature in your home down quicker. On cooler days, instead of programming your thermostat, open your windows and turn on your fans to circulate the cool air into the house and keep temperatures comfortable.
Giving your system a break when you can will lengthen the life of equipment and save you money on your energy bills.
Know when to call a professional.
Many HVAC manufacturers require annual preventative maintenance in order to maintain the unit’s warranty. Check your warranty to determine if/when maintenance is required by an HVAC professional.
If your system does require preventative maintenance, it is best to schedule your check-up for the cooling system in the spring and your heating system in the fall, before HVAC professionals get busy. HVAC professionals will check your system for problems, adjust loose bolts and wires, and address any other issues you may have.
