Fall Maintenance for Every Part of Lafayette
Lafayette is a big city with a range of housing, from century-old Craftsman homes in the Freetown-Port Rico neighborhood to brand-new construction in the subdivisions along Verot School Road. The heating equipment varies just as much. We see gas furnaces in older homes near downtown, heat pumps in the developments around Kaliste Saloom and Ambassador Caffery, and everything from package units to dual-fuel systems in between.
A heating tune-up accounts for whatever system you have and gets it ready for winter. We’ve been doing this across Lafayette since 1956, and our experience with the local housing stock means faster, more thorough inspections.
What a Heating Tune-Up Covers
This isn’t a quick filter swap and a handshake. Our technicians work through a full inspection checklist.
Gas furnace tune-up:
- Heat exchanger inspection for cracks, rust, or separation (the most critical safety item)
- Gas pressure testing at the manifold
- Burner cleaning and flame pattern inspection
- Ignitor condition check and resistance test
- Flame sensor cleaning
- Safety control testing (limit switches, pressure switches, rollout switches)
- Flue and exhaust pipe inspection
- Carbon monoxide testing at supply registers
- Thermostat calibration
- Blower motor amp draw and electrical connection inspection
Heat pump tune-up:
- Reversing valve operation test (confirms the switch from cooling to heating)
- Defrost board and sensor check
- Refrigerant charge verification
- Outdoor coil cleaning and inspection
- Auxiliary heat strip test
- Thermostat calibration for heat mode staging
The Inspection That Matters Most
The heat exchanger check is why professional maintenance exists. A cracked heat exchanger can leak carbon monoxide into your living space, and it’s not something you can see or smell without the right equipment. In Lafayette, the temperature swings between 30-degree mornings and 60-degree afternoons put real stress on heat exchanger metal over the years. We use visual inspection, combustion analysis, and CO monitoring to evaluate its condition thoroughly.
Why Lafayette Systems Need Fall Attention
Your heating system sat dormant from March through November. During those eight months, Lafayette’s relentless humidity crept into the cabinet, coated sensors with oxidation, and encouraged corrosion on electrical terminals. Dust settled on burner assemblies. Whatever was in the air when the system shut down in spring is still sitting in there.
For homes near the commercial corridors along Johnston Street or in the residential areas off Pinhook, where mature landscaping creates more shade and retains moisture, the effects are even more pronounced. We regularly find flame sensors so corroded during fall tune-ups that the furnace wouldn’t have stayed lit for more than a few seconds.
Gas Furnaces vs. Heat Pumps: Different Systems, Different Issues
Lafayette has a roughly even mix, which is unusual for South Louisiana. Many homeowners don’t even know which type they have.
Gas furnaces in Lafayette tend to have ignition problems after the long idle period. The ignitor, flame sensor, and gas valve all need to function in the correct sequence, and corrosion or dust on any one of them disrupts the chain. We clean and test each component during the tune-up.
Heat pumps face a different challenge: the reversing valve. This valve switches refrigerant flow between cooling and heating mode. If it sticks (and they do, especially after months in one position), you’ll get cool air when you switch to heat. Our tune-up cycles the valve and checks it under operating conditions so you don’t discover the problem on the first cold night.
Timing and Scheduling
October and November fill up fast. Lafayette is our largest service market, and fall tune-ups are our busiest season. If you wait until the first freeze warning, we’ll get to you, but you’ll be in a longer queue. Booking in early October gives you the most scheduling flexibility.
Homeowners who want both spring AC tune-ups and fall heating maintenance often save time by joining one of our maintenance plans, which schedules both visits automatically.
