Frequently Asked Questions
How often should I check my HVAC filter?
Pull the filter every month and look at it. Replace if the pleats are uniformly grey or saturated. The recommended replacement interval depends on MERV rating, household conditions, and runtime: MERV 8 baseline is 90 days, MERV 11 is 60 days, and MERV 13 is 45 days. Pets, allergies, smokers, urban air, and recent renovation each shorten the interval by roughly 30 percent.
What does the quarterly maintenance involve?
Quarterly DIY maintenance is the condensate drain flush (1 cup of distilled white vinegar poured into the access port near the air handler, allowed to sit 30 minutes, flushed with hot water) and a visual check of the indoor and outdoor coils for accumulated debris. Annual coil cleaning is the deeper task; quarterly checks catch problems early.
How much does an annual HVAC tune-up cost?
A typical annual professional HVAC tune-up runs 100 to 250 dollars depending on region and contractor. The visit covers refrigerant pressure check, capacitor microfarad reading, blower motor amp draw, gas pressure (on furnaces), and combustion safety. Many contractors offer a maintenance plan at 150 to 250 dollars per year that includes the spring AC visit and the fall furnace visit.
How long should I keep this log?
Keep filled-out logs for the life of your HVAC system, typically 15 to 20 years. The maintenance history is valuable when you sell the house (proof of consistent care raises buyer confidence) and during warranty claims (manufacturers may require maintenance records to honor the compressor warranty). Store completed logs in a folder with your other home maintenance records.
