Frequently Asked Questions
How do I know what size air filter I need?
To determine the correct size of your air filter, you can check for the air filter dimensions typically labeled on the side of the filter. Look for two size measurements: a ‘nominal’ size, often in larger print, and an ‘actual’ size, usually in smaller print. It’s crucial to get the right size filter for your HVAC system’s health. A filter that doesn’t fit properly won’t effectively capture airborne particles. If the filter is too small, it will leave gaps for debris to enter, while one that’s too large won’t fit into the slot. Trimming it down isn’t recommended, as it can create gaps allowing contaminants to bypass filtration. Alternatively, you can examine your existing air filter, measure it yourself, or measure the air register or air filter slot to ensure the correct size.
How often should I change my air filter?
To maintain optimal air quality, it’s recommended to replace your home’s air filters every 1-3 months, depending on factors such as the type of filter, the number of pets, and the presence of allergy sufferers. Mainstream Home Services provides professional air filter replacement services in Spokane Valley, WA, ensuring your HVAC system operates at peak performance.
How often does my A/C unit need maintenance?
You should schedule an AC maintenance tune-up at least once a year, typically in the spring before you begin using it for hot Spokane summers. Your air conditioner requires regular inspection for necessary repairs, cleaning of critical parts, and servicing of all functional components so you stay cool all summer long.
Why is A/C maintenance important?
Regular AC maintenance helps prevent future AC repairs later on. By having one of our expert HVAC technicians assess your air conditioner, we can find any small problems and fix them before it turns into an expensive air conditioning repair or replacement job.
With annual tune-ups and regular air duct cleaning, your air conditioner’s life span will extend, your utility bill will decrease in price, and you’ll have a nice and cool home. Why wait until there’s a huge problem with your air conditioner to give us a call? Do it now and avoid letting any issues pile up.
