Frequently Asked Questions

Component failures—compressors, heat exchangers, blower motors—represent the highest repair costs over a system's lifespan. A 10-year parts warranty covers these expensive replacements, protecting you from costs that often exceed $1,500. The 2-year labor warranty included with new American Standard installations covers the service work needed to complete those repairs.

Call immediately if your furnace stops working when outdoor temperatures drop below 20 degrees, if you smell gas near heating equipment, or if your AC fails during heat advisories affecting vulnerable household members. Non-emergency issues like minor temperature swings or higher utility bills can wait for standard scheduling.

Repair addresses specific failed components—capacitors, contactors, flame sensors—while the rest of the system continues operating. Replacement becomes more practical when multiple components fail within a short period, the system is over 15 years old, or refrigerant type makes parts expensive and scarce.

Extended cold stretches increase boiler run time, exposing marginal components like circulators and zone valves to failure. Heating systems that cycle normally in moderate weather often reveal pressure drops, air locks, or failing pumps when outdoor temperatures stay below 15 degrees for days.

Garner Heating And Cooling LLC stocks furnace filters and common furnace parts at their Tecumseh shop for customers who prefer to pick up supplies directly. This works well for standard filter replacements between service visits or when you know the specific part number needed.

The consultation evaluates electrical panel capacity, fuel source options—natural gas or propane—and transfer switch placement. Generator sizing depends on which circuits you want powered during outages: essential only, or whole-home coverage. Proper installation also accounts for local code requirements and utility notification procedures.

Gas line connections require pressure testing, proper threading and sealing compounds, code-compliant materials, and leak detection procedures that prevent dangerous failures. Licensed contractors carry insurance covering gas-related incidents and understand appliance BTU requirements that affect line sizing. Improper connections create carbon monoxide risk and potential fire hazards.

If repair costs exceed half the price of replacement, the system uses R-22 refrigerant that's expensive and limited, or the equipment is over 12 years old with declining efficiency, replacement makes more financial sense. Single-component failures on newer systems usually justify repair.

Duct layout complexity, total linear footage, number of registers and returns, and accessibility all affect pricing. Older homes around Tecumseh often have ductwork in crawlspaces or unconditioned attics that require more time to access. Homes with multiple HVAC zones or added-on sections typically have more extensive duct runs.

Schedule cleaning when clothes take longer to dry, the dryer exterior feels hotter than normal during operation, or you notice reduced airflow at the exterior vent hood. Homes with longer vent runs or multiple bends benefit from annual cleaning because lint accumulates faster in restricted pathways.

Thermostat replacement includes verifying wire compatibility with your heating and cooling equipment, configuring system type settings—single stage, two stage, or heat pump—and testing call sequences to confirm proper equipment response. Smart thermostats also require WiFi setup and calibration to match your system's actual performance.

Family-owned operations send the same experienced technicians who know your system history and home layout rather than rotating staff. Decisions about repair recommendations and pricing happen locally without corporate quotas. You're working directly with the people responsible for the quality of the work, not a regional call center.
