Homeowners across Haysville, Wichita, and rural Kansas communities are upgrading to 90% efficient furnaces to lower energy bills and reduce environmental impact. These high-efficiency systems are excellent for comfort — but they require proper venting and yearly maintenance to operate safely and efficiently.
Understanding how these furnaces work can help protect your home, your investment, and the environment.
Environmental Benefits of a 90% Furnace
A 90% furnace converts up to 90% of its fuel into usable heat, meaning:
-
Less wasted energy
-
Reduced fuel consumption
-
Lower greenhouse gas emissions
-
Smaller environmental footprint
For rural homes that rely heavily on propane or natural gas, this efficiency can make a significant difference in annual energy use.
Why Proper Venting Is Critical
Unlike older furnaces that vent through metal flues, 90% furnaces use PVC intake and exhaust pipes. These pipes:
-
Remove combustion gases safely
-
Bring in clean air for combustion
-
Prevent backdrafting and carbon monoxide risks
Improper venting can cause:
-
Reduced efficiency
-
Furnace shutdowns
-
Moisture damage
-
Unsafe combustion conditions
In rural areas around Wichita, vent pipes can become blocked by ice, debris, animals, or wind-driven snow, making inspections especially important.
Condensation: The Hidden Factor
High-efficiency furnaces produce condensation as part of normal operation. This moisture must drain properly through:
-
Condensate lines
-
Traps
-
Drain connections
If the drain becomes clogged or frozen, the furnace may:
-
Shut down
-
Leak water
-
Corrode internal components
-
Fail prematurely
Why Yearly Maintenance Is Essential
Annual furnace maintenance is not optional for a 90% system — it’s critical. A professional maintenance visit includes:
-
Vent pipe inspection
-
Condensate drain cleaning
-
Heat exchanger evaluation
-
Combustion and gas pressure testing
-
Safety control checks
-
Overall efficiency verification
Skipping yearly maintenance can reduce efficiency by up to 15%, increase energy costs, and shorten the life of the system.
DIY Tips Homeowners Can Do Safely
While professional service is essential, homeowners can help maintain performance with a few simple steps:
DIY Furnace Care Tips
-
✔️ Replace furnace filters every 1–3 months
-
✔️ Visually inspect PVC vent pipes for sagging or damage
-
✔️ Keep snow, leaves, and debris away from outdoor vent terminations
-
✔️ Check for water around the furnace base
-
✔️ Listen for unusual noises or frequent cycling
Never attempt to modify venting or drain lines yourself — incorrect adjustments can create safety hazards.
