Frequently Asked Questions

If you’re unsure when to replace your home’s air filter, watch out for these telltale signs indicating it’s time for a replacement. These indicators shed light on the crucial role air filters play in enhancing your home’s comfort and how a small investment of time and money can yield significant improvements:

  1. Visible Dust Around Vents: It’s time to replace your filters when you can see visible dust accumulating on and around vents.
  2. Dirty or Clogged Filter: A visibly dirty or clogged filter should be replaced promptly.
  3. Extended Heating/Cooling Cycles: Longer HVAC cycles signal reduced airflow due to a clogged filter.
  4. Higher Energy Bills: Increased energy consumption may result from a clogged filter.
  5. Declining Indoor Air Quality: Worsening air quality suggests an overdue filter replacement.
  6. Hot A/C Unit: Excessive heat from the A/C unit indicates restricted airflow, often due to a dirty filter.
  7. Uncertain Last Replacement: If you’re unsure when the filter was last changed, it’s likely overdue and time to be replaced.

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.

Typically, air filter manufacturers and HVAC experts advise replacing your air filter every 90 days, or roughly every 3 months. However, this timeline may vary based on several factors, including your home’s location (such as dusty or dry climates), the presence of pets, and the age of your HVAC system and equipment.

A lot of people neglect their furnace until it stops working, but an annual tune up of your home furnace can keep it in top shape for years to come. When it is not maintained, it has to work much harder to put out the same amount of heat, causing your furnace to burn out faster.

Your furnace and home will benefit greatly from a routine tune-up, and we are here to provide you with a detailed diagnostic report of anything we find. By having a professional take a look at your furnace, you can increase its lifespan, prevent damage, and avoid an early replacement.

Furnace maintenance is a service in which your furnace is professionally cleaned and maintained. Routine maintenance ensures that your unit runs at peak performance for as long as possible and avoids unnecessary breakdowns.

During a furnace maintenance appointment, our professional technicians will inspect your home’s furnace to ensure that all parts are safe and working properly. They will also be able to quickly identify and fix any issues before they can turn into costly repairs.

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.
