HVAC System Checkup

Six quick questions to gauge whether your heating and cooling system is ready for the next Des Moines season — with a score and a prioritized fix list you can act on today.

HVAC Readiness Scorecard

Is my HVAC system ready for the next season?

Readiness comes down to six basics. The two highest-impact habits are changing your filter every 90 days and getting one professional tune-up a year. Answer the six checks below to get a 0–100 readiness score and a prioritized fix list. In Des Moines, IA, a quick fall and spring once-over matters because the system has to swing from sub-zero heating to humid-summer cooling.

Have you changed or cleaned the air filter in the last 90 days?
Has a professional tuned up the system within the last year?
Is your thermostat working and able to hold a programmed schedule?
Are all supply vents and return registers open and unobstructed?
Is the system free of unusual noises, rattles, or burning/musty smells?
Is your system within its typical service life (AC about 14 yrs, furnace about 18)?

Prioritized fixes

  • 1Book a professional tune-up. Most manufacturers expect annual service to keep the warranty and efficiency intact.

Common misconception

“Skipping maintenance saves money.” It usually does the opposite. In Iowa, a neglected system works hardest in the deep-winter cold and the humid-summer peak — exactly when a missed tune-up turns a cheap part into a no-heat or no-cool emergency call. A seasonal tune-up is the cheapest insurance against that.

Common questions

How often should I check my HVAC system?

Do a quick self-check each spring and fall, change the filter about every 90 days, and get one professional tune-up a year. In Iowa that usually means a heating tune-up in fall and a cooling tune-up in spring.

What is the most important HVAC maintenance task?

The two highest-impact habits are changing the air filter on schedule and getting an annual professional tune-up. Together they prevent most avoidable breakdowns and keep the system running efficiently.

Does a maintenance plan help?

Yes. All Seasons HVAC maintenance plans schedule the seasonal tune-ups for you, so the system is checked before each IA heating and cooling season instead of after something goes wrong.
