Munn’s comes every 6 months to service our HVAC. They bring a laptop and hook it up to diagnostics and the report is with all the measurements in the system are emailed to you. They flush the system with a power suction pump, and take the casing off and clean and adjust things. That’s when they also change my filter. Same price if the come once a year or twice a year. It’s a small fee for an important item in your house. Money well spent as far as I’m concerned.
