Fishers, IN Heating Repair

If your furnace is running but the house still feels chilly, or you’ve started hearing loud pops, rattles, or whines, it’s time to take a closer look. Maybe it’s blowing cold air, cycling on and off too quickly, or not turning on at all. These are all signs that something inside isn’t working the way it should.

Common furnace repairs include:

• Replacing worn ignitors or flame sensors that prevent proper startup
• Cleaning or repairing blower motors to restore strong airflow
• Fixing thermostat or control board issues that cause short cycling

Before calling, check that your thermostat is set to “heat,” your filter isn’t clogged, and your circuit breaker hasn’t tripped. If everything looks normal but the furnace still won’t cooperate, schedule your Fishers furnace repair with Thiele—we’ll get to the bottom of it and have your home warm again fast.

Maybe some rooms are staying cold, the radiators are gurgling, or you’ve spotted a little water around the base of the unit. Boilers usually give you a few hints before they quit completely, and catching those signs early can save you from a bigger repair later.

Common boiler repairs include:

• Replacing a worn circulation pump when certain rooms stay cold
• Fixing leaks or faulty pressure valves
• Flushing out trapped air or mineral buildup that blocks heat flow

If your heat feels uneven, check that your thermostat is set correctly and that the boiler’s pressure gauge reads between 12–15 psi. If it’s outside that range, try resetting the system or topping up the pressure if your model allows. But if you’re still not getting heat—or you’ve noticed leaks, knocking sounds, or a drop in pressure—let us know. We’ll pinpoint the problem and take care of your Fishers boiler repair.

Air-source heat pumps work hard year-round, which means they can run into problems from time to time. You might be noticing that your system is blowing cool air in heating mode, running nonstop, or icing over outside. A ductless mini-split is another type of heat pump, and if you have one in your finished basement, home office, or bonus room that’s not heating evenly or showing an error light, we can fix that too.

Common heat pump repairs include:

• Replacing faulty sensors, fan motors, or reversing valves
• Sealing refrigerant leaks and recharging the system
• Defrosting outdoor coils and repairing defrost controls

If your heat pump won’t switch modes, freezes up often, or just can’t keep up with demand, make sure the air filter is clean and the outdoor unit isn’t blocked by debris. When that doesn’t solve it, schedule your Fishers heat pump repair with Thiele—we’ll find the issue and get your system back to keeping your home comfortable.

When your geothermal system isn’t working properly, it can be tough to tell what’s wrong—it’s not like you can see the pipes buried underground. Maybe your house isn’t heating evenly, the system’s running nonstop, or your utility bill suddenly jumped. These are often signs that something simple, like a loop leak, a weak pump, or a sensor failure, needs attention.

Common geothermal repairs include:

• Repairing leaks or blockages in the underground loop
• Replacing worn pumps or faulty control sensors
• Cleaning and recalibrating the indoor heat exchanger for better performance

If your home feels cooler than it should or your system can’t seem to catch up, check your thermostat and circuit breakers first. But when it’s still malfunctioning, call Thiele for your Fishers geothermal system repair.
