For Ann Arbor residents, South Lyon HVAC is the way around every bad HVAC experience you've heard about: the vague quotes, the mystery invoices, the replacement pitch for a system that needed a $40 part. That's not how we work. You talk to a real person, a technician shows up on time, the diagnosis is explained in plain language, and the price is agreed before any work begins. From emergency repairs to planned upgrades, all handled by seasoned technicians who know the area.

Full-Service HVAC Care for Ann Arbor Homes and Businesses

Whether you own a townhouse, a small apartment building, or a commercial space in town, we have the expertise and equipment to handle the full range of heating and cooling work. Our technicians bring years of hands-on experience with central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits throughout the area, and we pay close attention to the climate patterns, housing stock, and local code requirements that shape how systems perform in this area.

A normal week for our residential team might include capacitor and contactor replacements, flame sensor cleanings, refrigerant leak repairs, blower motor swaps, plus the occasional full system replacement or ductless addition. When we do replace equipment, we size it with a room-by-room load calculation rather than matching the old unit. A correctly sized system keeps rooms even, keeps utility bills reasonable, and avoids the short-cycling that kills compressors early. Beyond repairs and replacements, we offer seasonal tune-ups that clean coils, confirm the refrigerant charge, test safety controls, and measure static pressure, the best thing you can do for longer equipment life.

For commercial property owners and managers nearby, we service the rooftop units, split systems, and makeup air and ventilation equipment that restaurants, shops, offices, and apartment buildings depend on. We understand that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, carry common parts on the truck, and schedule work around your operating hours whenever we can.

When Your System Fails in Ann Arbor

Heating and cooling failures rarely wait for a convenient day, which is why we offer fast, flexible scheduling for most situations. When you call, you'll speak with a real person who will get a technician headed to your property quickly. Arrival in the area is usually within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is the kind of call we move to the front of the line.

Here's what we see most often when something breaks at home: an air conditioner blowing warm air, a condenser that hums but won't start, a furnace that ignites and shuts off, a breaker that keeps tripping, an evaporator coil that has frozen, a condensate drain backed up into the furnace cabinet, or a thermostat that has quit. Most of them trace back to parts already on our trucks: capacitors, contactors, igniters, flame sensors, universal control boards, and standard fittings. You get the price before any work starts, with no surprises on the invoice.

Two situations call for a quick step from you before our technician gets there. The first is an iced-over air conditioner: turn the system off at the thermostat and set the fan to "on" so the moving air thaws the coil, because running it frozen can flood the drain pan and hurt the compressor. The second is a furnace that short-cycles or produces a burning smell. Turn it off at the service switch and call us. That small step can save you from a far bigger repair.

Keeping Your Ann Arbor HVAC System Running Longer

Many mid-season breakdowns trace back to skipped maintenance, and the habits that prevent them are easy. Change your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and rinse the condenser coil once a year in spring. Then book a professional tune-up twice a year, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.

How old is your system? That number tells you a lot. With regular service, most air conditioners make it to 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is beyond that range and also shows rising bills, rooms that never quite reach temperature, or frequent repairs, it's a strong candidate for a planned replacement, which is almost always cheaper and easier on everyone than an emergency replacement in peak season.

Small problems don't stay minor for long. Consider a weak capacitor: replacing it is a quick, inexpensive repair, but if it's ignored for a season, it can take the compressor with it, and suddenly a minor fix has become a full system replacement. That's why we ask homeowners to keep our number in their phone and call at the first sign of trouble. Catching it early saves money and spares you a few miserable nights.

Common HVAC Problems in Ann Arbor

The service calls we run around here tend to follow the calendar. In summer it's warm air from the vents, weak capacitors that finally quit on the first hot week, and iced-over evaporator coils. In winter it's furnaces that light and shut back down, dirty flame sensors, and igniters that fail on the first cold night. Year-round we see clogged filters choking airflow, rising energy bills from dirty coils, and ductwork that leaks conditioned air into attics and crawlspaces. Every one of these starts small, and every one is cheaper to fix early. If your system is acting up, call (248) 260-5437 before the season turns it into an emergency.

HVAC FAQ for Local Residents

Start with a few quick checks: confirm the thermostat is set to cool with working batteries, pull the filter and check for a clog, and look for a tripped breaker on both the indoor and outdoor units. If everything looks normal and the outdoor unit is humming without starting, or you see ice on the copper lines, turn the system off to protect the compressor. Then call (248) 260-5437 and we'll send a technician to your home as fast as we can.
We do both. Most calls start as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from every major brand. If a system can't be saved, we manage the whole replacement, from sizing the new equipment and removing the old unit to installation and testing in every mode. Whichever way it goes, you'll see clear pricing for both options before anything happens.
All major brands, such as Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can source brand-specific components quickly when a repair calls for them.
Most repairs land between $150 and $650 depending on the part and system type, while full system replacements usually run from around $5,000 to $12,000 installed, depending on size and efficiency. Every job starts with a diagnostic and a written, upfront quote. The price you approve is the price you pay, with no surprise line items.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit focuses on cooling: cleaning the coils, verifying the refrigerant charge, testing the capacitor, and measuring airflow. The fall visit covers heating: burner cleaning, a combustion check, and safety control testing. Staying on that schedule extends equipment life, helps prevent breakdowns in the middle of a heat wave or cold snap, and often pays for itself in lower energy bills.
It comes down to age and which part failed. Under about 10 years, most component failures are worth fixing. Past 15 years, or any time a compressor or heat exchanger fails, replacement is usually the smarter investment, especially given how much more efficient new equipment is. We give you both numbers straight and let you make the call. We'd rather earn your trust than sell you a system before you need one.
Usually the same day. No-heat and no-cooling calls take priority over routine maintenance, and we'll give you an honest arrival time when you call (248) 260-5437. Once our technician arrives, capacitors, contactors, igniters, and motors are already on the truck, so the majority of problems are fixed without a second trip.
Yes. Mini-splits are a great fit for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the actual room, position the indoor and outdoor units carefully, and take care of the line set, condensate drainage, and electrical connections correctly. If central equipment serves you better, we'll tell you that too.
