How quickly can you respond to a no-heat or no-AC emergency?

Same-day service throughout Lenawee County and surrounding areas. During business hours, most emergency calls get a technician within 2-4 hours. After-hours, we run an emergency rotation — call or text 517-423-3121 and a real person picks up.

Do you offer free estimates on new HVAC system installations?

Yes — free, no-obligation in-home estimates on every furnace, AC, heat pump, and mini-split install. A technician walks your home, measures your space and checks insulation so we size the equipment to your actual home (not whatever the last guy installed), walks you through good/better/best options, and leaves you with a written quote on the spot. No high-pressure close.

What brands of HVAC equipment do you install?

We're a Lennox Premier Dealer and Carrier Factory Authorized Dealer — those are our two install lines because they've proven reliable in Michigan's climate over 45 years of installs. We service and repair every major brand: Trane, Bryant, Goodman, Rheem, York, American Standard, Amana, Heil — if it's on the side of your unit, we work on it.

How often should I have my furnace and AC serviced?

Once a year, each — furnace in the fall, AC in the spring. A 20-minute tune-up catches the small stuff (worn capacitors, low refrigerant, dirty burners) before it becomes an emergency repair, extends equipment life 30-40%, and keeps the manufacturer warranty in force. Our ClimateGuard Premier plan bundles both visits at a discount.

Onsted homes — what we typically work on

Onsted village is small; most of our work in this area is on the surrounding rural housing stock and around the lakes south of M-50. Lake homes (Devil's Lake, Round Lake, Sand Lake) often need seasonal HVAC and plumbing service.

Climate & utility notes for Onsted

Equipment in this part of Michigan works hard year-round: January lows often hit -5 to -10°F, July highs push 90°F with high humidity, and Lake Erie influence pushes through both seasons. Inland-lake effect from the chain of lakes south of town adds moisture in summer and snow squalls in winter.

Common service calls in Onsted

Seasonal lake-home plumbing winterization

Lake homes left empty over winter need proper plumbing winterization. We handle full winterizations, de-winterizations in spring, and emergency thaw service for properties that got missed.

Mini-splits for lake cottages without ductwork

Older lake cottages often have window units and electric baseboard. Ductless mini-splits give these homes proper year-round comfort without tearing into the building.

A little about Onsted

13 miles from our shop

Onsted is a Lenawee County village of about 900 residents, thirteen miles west of Tecumseh along M-50. The village itself is small, but Onsted's name covers a much larger service area — the chain of inland lakes immediately south (Devil's Lake, Round Lake, Sand Lake, and others) sits within the same school district and ZIP code, and many of our service calls in this area are at lake homes around the Irish Hills.

Hayes State Park and the Walter J. Hayes Recreation Area draw heavy summer traffic, and a meaningful share of Onsted's housing is seasonal cottages that have been converted to year-round homes over the past 20-30 years. Onsted Community Schools serves the whole area.
