Why It Matters
Why Timing and Safety Matter
Most no-heat breakdowns start as small warning signs, an odd noise, a short cycle, or weak heat, months before the system finally quits. Catching those early usually means a simpler, cheaper repair on your schedule instead of an emergency call on the coldest night, when every HVAC company in the area is buried at once.
Heating safety is not something to leave to chance. Fuel-burning furnaces need correct venting and a sound heat exchanger to keep carbon monoxide out of your home, which is why our maintenance visits always include a thorough safety check. Done right, your heating system keeps you both warm and safe all winter long.

Frequently Asked Questions
How long does a furnace last?
Gas furnaces typically last 15 to 20 years, and electric furnaces often reach 20 to 30 years. Annual maintenance is the single best way to extend your furnace's life and keep it running safely.
How often should I change my furnace filter?
Every 30 to 90 days for standard filters. During Iowa's bitter-cold stretches your furnace runs long hours, so check monthly and change at least every 60 days, more often with pets or allergies.
Why is my furnace blowing cold air?
Common causes include a thermostat set to ON instead of AUTO, a dirty filter, or a pilot or ignition problem. If a quick filter and thermostat check does not fix it, give us a call and we will diagnose the real cause.
Do heat pumps work in Iowa winters?
Yes. Modern cold-climate heat pumps heat effectively even below zero, and in Southwest Iowa we often pair them with a gas furnace in a dual-fuel setup so you get efficiency most of the year and reliable backup on the coldest nights.
Why does my furnace keep turning on and off?
Short-cycling is usually a clogged filter, an oversized furnace, or a faulty flame sensor or thermostat. It stresses the system and raises your bills, so it is worth a service call before it becomes a breakdown.
