Maintenance agreements keep you up to date on best practices for home HVAC unit care.
You can count on maintenance agreements to help you with all of the HVAC filter changes you’ll need throughout the year. Discuss the best schedule for swapping them out with the technician who visits your home. You can even ask for a demonstration, so you’re never worried about making a mistake and causing a problem for your HVAC system.
Your filter changing schedule depends on a number of factors:
- What is the MERV rating of your filter? MERV stands for Minimum Efficiency Reporting Value. It’s a numeric rating system aimed to help people choose filters based on how many contaminants they want removed from their indoor air. The higher the MERV rating, the more contaminants are removed and the faster a filter will be clogged and need to be changed.
- How clean are your ducts (and your house)? The more dirt and debris that winds up in your ductwork, the more particles will be caught in your filter. It makes sense to change a dirty filter as soon as is reasonable. Dirty units will block the flow of air and lead to energy waste.
- What size filter does your system take? There are plenty of sizes which work well with flat, affordable air filters. Others require ultra-thick filters or permanent, washable units that need to be changed just a few times a year.
Maintenance agreements often provide just two HVAC visits a year. Make the most of them by asking your technician how to better maintain your units in the meantime.
