Heating Services in Leawood, KS
A Johnson County winter is built around a roughly 13°F design low, with cold snaps that drop well below it. On those nights your heating system isn’t a convenience — it’s the thing keeping pipes from freezing and your family warm. 7th Degree Heating and Air installs, repairs, and maintains furnaces, heat pumps, and boilers across Leawood and eastern Johnson County, and we treat every gas appliance as the combustion device it is: verified, measured, and checked for carbon monoxide before we leave.
Heat That Holds Up on the Coldest Night
The most common winter failures we see — a furnace that short-cycles, won’t ignite, or blows cool air — usually trace to a handful of causes: a clogged inducer or pressure switch, a failed hot surface igniter, a dirty flame sensor, or a cracked heat exchanger. They produce overlapping symptoms, which is why we diagnose with instruments. We run combustion analysis, confirm manifold gas pressure, and measure carbon monoxide air-free against manufacturer spec. A cracked heat exchanger is both a comfort failure and a safety hazard, and we don’t condemn one we haven’t inspected with a borescope.
Our Heating Services
Furnace Installation
Right-sized, Manual J–based gas and electric furnace installation, with venting per code and combustion verified on startup.
Furnace Repair
Instrument-based diagnosis of no-heat and short-cycling calls — igniters, flame sensors, pressure switches, blower motors, and control boards.
Furnace Tune-Up
Fall maintenance that cleans the burner and flame sensor, checks the heat exchanger, and verifies safe combustion before the heating season.
Heat Pumps
Installation and service of heat pumps, including dual-fuel setups that lean on a gas furnace for backup when temperatures drop below a heat pump’s efficient range.
Heat Exchanger Repair
Inspection, repair, and replacement of cracked or failing heat exchangers — the component most directly tied to carbon monoxide risk.
Boiler Installation
Installation of hot-water and steam boilers, common in older Leawood and Johnson County homes with hydronic and radiator heat.
Boiler Repair
Repair of leaks, circulation problems, and controls on cast iron and modulating-condensing boilers.
Gas Line Installation
Safe gas line installation and modification for furnaces, boilers, and relocated equipment, with pressure verified on your natural gas service.
Frequently Asked Questions
- How do I know if my furnace needs repair or replacement?
- Age and the nature of the failure decide it. A furnace under 12–15 years old with a failed igniter, flame sensor, or pressure switch is almost always worth repairing. Once a unit is past 15 years, has a cracked heat exchanger, or needs a major component on top of declining efficiency, replacement usually wins on both cost and safety. We give you the repair-versus-replace numbers after we diagnose, not before.
- Why is a cracked heat exchanger dangerous?
- The heat exchanger separates combustion gases — including carbon monoxide — from the air your blower pushes through the house. A crack can let CO mix into that airstream. It’s the reason we check carbon monoxide air-free and inspect the exchanger on every furnace visit, and the reason we won’t sign off on a furnace we believe is compromised.
- Do heat pumps actually work in Kansas winters?
- Yes, with the right setup. Standard heat pumps lose capacity as temperatures fall, and Johnson County’s design low near 13°F is below where a basic unit stays efficient. A dual-fuel system pairs a heat pump with a gas furnace that takes over on the coldest days, or a cold-climate heat pump rated for low-temperature performance handles more of the season on its own. We size and select based on your home and the local design temperature, not an optimistic lab rating.
- How often should I have my furnace serviced?
- Once a year, in the fall before heating season. A tune-up cleans the flame sensor and burner, checks the heat exchanger, and verifies safe combustion — catching the small problems that otherwise become a no-heat call on the coldest night of January.
- What are the signs of a carbon monoxide problem?
- Headaches, dizziness, or nausea that improve when you leave the house, soot or staining around the furnace, a persistent yellow rather than blue burner flame, and of course a CO detector alarm. Carbon monoxide is colorless and odorless, so a working detector on every level of the home is essential — and if one alarms, leave and call us and emergency services.
