Furnace Repair in Leawood, KS
A furnace that quits on a single-digit January night isn’t a someday problem — it’s a tonight problem, with pipes and comfort on the line. 7th Degree Heating and Air diagnoses heating failures in Leawood with instruments, fixes the real fault fast, and checks the one thing every furnace repair should never skip: carbon monoxide. Our emergency line is staffed around the clock through every Kansas cold snap.
How We Diagnose a Furnace
No-heat and short-cycling calls usually trace to a handful of culprits, and the symptoms overlap enough that guessing wastes your money. We work through them methodically: a dirty flame sensor (the single most common no-heat cause), a cracked or failed hot surface igniter, a clogged pressure switch or condensate trap, a tripped limit switch from restricted airflow, a failing blower motor, or a control board fault. We confirm with combustion analysis, manifold gas pressure, and an air-free carbon monoxide reading — because a heating repair that ignores combustion safety isn’t a complete repair.
Common Furnace Problems We Fix
- Furnace won’t ignite — usually a dirty flame sensor or a failed igniter; both are common, fixable, and inexpensive caught early.
- Blowing cold air — a flame sensor dropping out, a gas supply issue, or a control problem.
- Short-cycling — overheating from restricted airflow, a failing limit switch, or a flame sensor issue.
- Loud bangs or booms on startup — delayed ignition, which is worth addressing promptly for safety.
- Furnace runs but house won’t warm — airflow, ductwork, or a unit that’s failing under the coldest loads.
Frequently Asked Questions
- What are the most common furnace problems?
- A dirty flame sensor tops the list — it’s the cheap, common reason a furnace lights and then shuts right back off. Failed hot surface igniters, clogged pressure switches and condensate traps, tripped limit switches from airflow restriction, and worn blower motors round out most of what we see. The majority are quick fixes once correctly diagnosed.
- Why won’t my furnace ignite?
- Most often a dirty flame sensor or a failed igniter. The flame sensor tells the control board the burner actually lit; when it’s coated, the board shuts the gas off as a safety measure, so the furnace lights briefly and quits. A cracked igniter simply never gets the burner going. Both are common and inexpensive to fix.
- Why is my furnace blowing cold air?
- Commonly a flame sensor that’s failing to confirm the flame, a gas supply or ignition problem, or the blower running while the burner isn’t lit. We diagnose which it is rather than guessing — and we check combustion safety as part of the visit.
- Is it safe to keep running a furnace that’s acting up?
- It depends on the symptom. Banging on startup, soot, a yellow burner flame, or any CO detector activity means stop and call us. A furnace that simply won’t start isn’t dangerous, but we’d rather check it than have you run something that might have a combustion or heat-exchanger problem. When in doubt, we’ll talk it through on the phone.
- Do you offer emergency furnace repair?
- Yes. Our line at (913) 354-6552 is staffed 24/7, including holidays. A no-heat call during a Kansas cold snap gets same-day priority, and being based in Leawood keeps our response time short across eastern Johnson County.
