What South Lyon Homes Throw at Us
South Lyon started as a railroad town. Its 1909 Witch's Hat Depot still stands in McHattie Park. Most of the city's homes came much later: South Lyon doubled in size between 1970 and 1980, then grew another 55% in the 1990s. About four in ten homes are in condos and other multi-unit buildings.
- Homes from the growth years. The average South Lyon home was built in the 1980s, and a big wave followed in the 1990s. Furnaces and AC in houses that age may be original or on their second round, and either way they deserve a hard look. We check what you have and tell you straight whether repair or replacement makes more sense.
- Condos and attached homes. Tight mechanical closets, outdoor units lined up along the building, and association rules on what can change outside. We size the equipment to fit the space and plan the outdoor unit around your HOA's requirements.
- New refrigerant, new testing. Many new air conditioners and heat pumps use A2L refrigerants. Since November 1, 2025, the city requires A2L refrigerant systems to be tested under the 2021 Mechanical Code. We follow that rule and handle the permit and inspection on installs.
- City limits or township? The South Lyon mailing address covers the city and four surrounding townships, and each one runs its own permits. We confirm who covers your address before we pull a permit.
What We Do in South Lyon
Furnace repair and replacement
No heat moves you up the list. We track down what failed and give you a flat-rate price before any work starts. If a repair will do the job, we say so. If replacement makes more sense, we walk you through why.
Heating Service
AC and heat pumps
Central air, heat pumps and ductless mini-splits, sized for everything from a ranch house to a second-floor condo.
AC Service
Tune-ups and the AirFlow Maintenance Agreement
A tune-up once a year finds small problems before they turn into big repairs. The AirFlow Maintenance Agreement covers a furnace tune-up and an AC tune-up every year, plus gas leak and carbon monoxide testing and a water heater flush. You also get priority scheduling, no diagnostic fee during business hours, and discounts on parts and replacements.

Winter air that dries you out, dust that settles right back, rooms that never feel comfortable. Humidifiers, air purifiers and better filtration.

Common Questions From South Lyon Homeowners
Do you cover all of South Lyon?
Yes. We take calls from across South Lyon. R&L has four offices, in Taylor, Madison Heights, Trenton and Ann Arbor. Call or request service online and we'll get you on the schedule.
Who issues the permit for a new furnace or AC in South Lyon?
Inside city limits, the City of South Lyon Building Department issues mechanical permits, and it has a separate form for residential HVAC replacement. A South Lyon mailing address doesn't always mean city limits, so we confirm which office covers your home first. We pull the right permit and handle the inspection on installs.
I live in a condo. Can you replace my furnace and AC?
Yes. We check the space you have and where the outdoor unit can go, and we work with your association's rules on exterior changes. Ask your HOA if they need to sign off before install day.
My Daikin was installed by another company. Will you work on it?
Yes. Repairs, tune-ups and replacements, no matter who put it in.
My house has no ductwork in some rooms. Can I still get AC there?
Yes. A ductless mini-split cools the rooms you pick without running new ducts.
