Heating Repair Services We Provide in Lawrence

Furnace Repair (Gas and Electric)

If your furnace won't start, keeps turning on and off, or isn't heating your home, our technicians inspect the system to find the problem. We repair ignition systems, blower motors, thermostats, electrical components, and other issues that require heating repair in Lawrence, KS.

If your furnace has reached the end of its service life, we'll explain your repair and heating replacement options, so you understand the long-term costs before making a decision.

Heat Pump Repair

Heat pumps can develop heating problems that leave your home colder than the thermostat setting. Low heating output, ice on the outdoor unit, long heating cycles, and unusual noises are all signs the system needs inspection.

Common signs include:

• Reduced heating output
• Ice buildup on the outdoor unit
• Long heating cycles
• Unusual noises
• Rising utility bills

Our technicians inspect the heat pump, locate the cause, and complete the necessary heat pump repair.

Thermostat and Control Issues

Faulty thermostats, damaged wiring, failed sensors, or communication problems can prevent the heating system from operating correctly. Our technicians inspect these components during every diagnosis so the actual source of the problem is identified before repairs begin.

Gas Furnace Repair: What Lawrence Homeowners Should Know

Gas furnaces remain one of the most common heating systems in Lawrence, making gas furnace repair an important part of our heating services.

Ignition failures, dirty flame sensors, pilot problems on older systems, pressure switch faults, blower issues, and short cycling are all common repairs during Kansas winters.

If you smell natural gas inside your home, leave the building immediately and contact your gas utility from a safe location. After the area has been declared safe, Dunco can inspect the furnace and complete the repairs needed before the system is returned to service.

Ignoring gas furnace problems can allow small component failures to become larger repairs over time.

Signs Your Furnace Needs Repair

Furnace Blowing Cold Air

A furnace blowing cold air does not always mean the furnace has failed. Dirty filters, ignition problems, thermostat settings, airflow restrictions, and safety controls can interrupt the heating cycle and require professional diagnosis.

Short Cycling

A furnace that starts and stops repeatedly experiences unnecessary wear. Dirty filters, overheating, thermostat problems, and equipment sizing issues are common causes.

Uneven Heating

Cold rooms while other areas remain comfortable often point to airflow restrictions, duct problems, blower issues, or thermostat concerns that need inspection.

Rising Utility Bills

An unexplained increase in heating costs frequently means the system is working harder than it should because of worn components, airflow restrictions, or declining efficiency.

Strange Noises

Grinding, squealing, rattling, or banging sounds should never be ignored. These noises indicate loose parts, worn bearings, blower problems, or failing motors that should be repaired before additional damage occurs.

Routine furnace maintenance and tune-ups identify many of these issues before they lead to an unexpected breakdown.

Repair or Replace? How to Decide

Not every heating problem requires a new furnace.

If the equipment has been repaired several times, replacement parts are becoming difficult to find, or utility costs continue increasing, replacing the system may be the better long-term investment.

Waiting until the furnace fails during a Douglas County cold snap also limits your options and can result in the Emergency Tax of replacing equipment under pressure instead of planning ahead.

For homeowners preparing for replacement, Dunco offers financing options that allow qualified customers to spread the investment into manageable monthly payments instead of facing one large expense at once.
