From the owner
“For us it's simple — take care of the customer first, and stand behind the quality of our work. That's how my team has done it for over 35 years, and it's not going to change.”
Mitch HinrichsenHinrichsen Heating & Air Conditioning Nearly 80 years of combined technician experience backs every maintenance visit — the same craftsmanship-first standard Mitch's team has stood behind for more than three decades.
For most homes we service, yes — starting at $130 per visit, with a free first hour of labor on follow-up service calls after your seasonal check. Nearly 80 years of combined technician experience shows up in the work, not just the brochure. Here’s exactly what a visit includes.
Two documented tune-ups each year — cooling prep in spring and heating startup in fall — with readings checked against factory spec, filter and airflow condition logged, and written findings with photos when something needs attention.
Complete a seasonal maintenance check and your next follow-up service call includes the first hour of labor free. That’s the differentiator that keeps small issues from turning into expensive surprises.
After you’ve completed a seasonal maintenance visit with us, any follow-up service call starts with the first hour of labor at no charge. It’s built for customers who stay on a maintenance schedule — not a one-time coupon.
Ask the office when you book so the visit is tagged correctly on your account.
Because our equipment works both ends of the thermometer. A system that idles through a mild coastal winter gets a pass; a Goodfield or Peoria system runs hard through July humidity and then again through January cold, often within the same year of ownership.
The failure pattern we see most is simple: the systems that die young are the ones nobody looked at. Skipped fall tune-ups become mid-January no-heat calls; a clogged condensate line in June becomes a shut-down AC on the hottest weekend. Twice-a-year maintenance exists to catch exactly those failures while they're still cheap.
It protects it. Registered Daikin systems carry a 12-year parts limited warranty and WaterFurnace geothermal systems carry 10-year parts and labor coverage — and manufacturers expect the equipment to have been reasonably maintained when they review a claim.
Because visits are documented, your service history is on file with us. If you ever need a manufacturer review, the paper trail already exists.
Yes — geothermal is our specialty. We've installed more than 1,000 geothermal systems since 1987, and we maintain what we install: loop pressures, flow rates, and heat-of-extraction checks that a generalist tune-up simply skips.
If another company installed your geothermal system, we can still take over its maintenance — that's a common way new customers find us.
Seasonal maintenance starts at $130 per visit. Exact pricing can vary by system type (a geothermal loop check is a different visit than a gas furnace tune-up). Call (309) 965-2604 and the office will confirm the rate for your equipment in one call.
