How Our Process Works

When you contact us for a repair, we gather details about your symptoms—strange noises, weak airflow, intermittent operation—and schedule a service window that fits your day. A licensed technician arrives in Lansing with diagnostic tools, replacement capacitors, contactors, thermostats, and refrigerant, ready to identify and resolve the issue on the spot whenever possible.

After a thorough system inspection, the technician explains the problem in plain language and provides an upfront estimate before beginning any work. Treadwell Mechanical - Heating & Cooling prioritizes transparency, so you know exactly what you're paying for and why the repair matters. Most service calls are completed within two hours, restoring airflow, heat output, or cooling capacity.

Once the repair is finished, the technician tests your system under normal operating conditions, verifies thermostat calibration, and checks for secondary issues that could cause future breakdowns. You receive a detailed invoice and maintenance recommendations to keep your equipment running smoothly through every season.

What's Included in This Service

Repair concerns vary widely depending on system age, usage patterns, and local conditions. These questions cover the most frequent issues we resolve for homeowners in Lansing and surrounding communities.

What causes frozen evaporator coils?
Low refrigerant levels, dirty filters, or restricted airflow force coils to drop below freezing. We identify the root cause, thaw the coils safely, and restore proper refrigerant charge or airflow.
Can you repair heat pumps?
Yes, our technicians are trained on heat pump reversing valves, defrost controls, and auxiliary heating elements common in Michigan installations. We handle both heating and cooling mode failures.
How do I know if I need a repair or a replacement?
If your system is less than twelve years old and the repair cost is under half the replacement price, repair usually makes sense. We provide both options with clear cost breakdowns so you can decide.
Do you service all brands?

We repair all major HVAC brands, including Carrier, Trane, Lennox, Rheem, Goodman, and Bryant. Our service vehicles carry universal parts that fit most residential systems in Lansing.

What's your typical response time?
