A Mechanical Contractor Guild to HVAC Maintenance

In order for an HVAC system to work at maximum efficiency, the air filters should be changed once every three months. An easy way to remember that is to do it with your oil change, or with the change of the seasons. This is just one of the most basic maintenance tips for HVAC systems for a mechanical contractor.

As Bay Area mechanical contractors, we get a lot of HVAC work. All good HVAC manufacturers and mechanical contractors will tell you that regular maintenance on an HVAC system is absolutely critical, especially in the Bay Area where there is a lot of salt in the air. Here are some of the most important HVAC maintenance tips:

Check The Filters, Replace Before Necessary: Although the general guideline is to replace your air filters once every three months, for some HVAC systems, it may be necessary to do so more often. Inspecting the air filter monthly is a great way to stay on top of your HVAC maintenance. The great thing too is that inspecting the air filter only takes a couple of minutes and can be done by almost anyone. Replacing the air filter before necessary is important to keeping the overall health of your HVAC unit. Set a reminder in your phone each month to check the air filter and replace it when needed. Some factors that contribute to replacing air filters more often are: pets in the home, living in the Bay Area, leaving windows open frequently.

Clear Debris from AC and Heating Units: If you have an outdoor unit, keep the system completely free from debris. This should be a weekly task. Clear the leaves, pollen, dirt, sticks, and anything else that manages to build up on the HVAC unit. Use gloves and even a hose if necessary to do so. This will increase the airflow of the unit and make your HVAC system more efficient and increase its lifespan. For extra measure, keep a two foot parameter clear around the unit to guarantee maximum airflow.

Clean the Registers: Cleaning the registers is another task that should be preferred as often as possible. Ideally weekly. Keeping the registers and ducts clean of dust and debris will help increase the lifespan of your HVAC unit and help you avoid costly repairs in the future.

Rest the Humidifier: During the summer, consider turning off the furnace humidifier’s water supply. This will give the humidifier extra life as it is not constantly running in months where it is unnecessary to do so. As the cooler months get nearer, replace the humidifier pad and set the relative humidity back to 35 to 45 percent. Then turn the water supply to the furnace humidifier back on.

Listen for Odd Noises: No need to get all Sherlock Holmes on your HVAC, but if you start to observe odd noises coming from your unit, it might be time to call in a mechanical contractor. Odd noises are usually caused by blockages in the register, loose bolts, or debris in the vents. Be sure to get these checked out immediately as they could cause further damage the HVAC unit if left unchecked.

Use Indoor Fans: Sometimes it is a good idea to give your entire system a break. On hot summer days, consider using ceiling fans or portable fans to circulate air throughout the house. Open your windows in the evening and night to allow the cool air to flow through the home. Not only will this help your HVAC system have a longer lifespan, it can also save you significant money on your energy bill each month. Get creative and realize that it isn’t always necessary to crank the AC to cool the home.

When it’s time, make the call: Make sure to call a mechanical contractor when necessary. There is no reason to suffer through an unbearably hot summer because your HVAC system isn’t working.
