Stay Cozy and Warm with Fast, Reliable Heating Repair

A broken furnace is a major problem. For a homeowner, it’s a stressful, frozen-pipe-worrying nightmare. For a business owner, it’s a shutdown that costs you customers and productivity.

Whether your system is making a strange noise, blowing cold air, or has quit entirely, you need a heating repair company you can trust. R.D. Davis Heating and Air Conditioning is Springfield’s 3rd-generation, family-owned repair expert. Our certified technicians are here to get your heat back on, with fast, reliable service for all makes and models.

Common Heating Problems We Fix Every Day

Our certified technicians have seen it all and can service all makes and models. If you’re experiencing any of these issues, give us a call right away—day or night.

  • Your Furnace is Blowing Cold Air: This is one of the most common calls we get. It can be caused by a simple thermostat issue, a clogged filter, or a faulty ignition system.
  • Your Furnace Won’t Turn On: If your system is completely dead, it could be a tripped breaker, a safety switch, or an issue with the pilot light or ignitor.
  • You Hear Loud Noises: Banging, grinding, or squealing are all warning signs. Banging can be delayed ignition, while grinding often points to a serious motor or bearing issue.
  • Your System is Short-Cycling: Is your furnace turning on and off every few minutes? This is often a sign of a clogged filter or a failing component.
  • You Smell Gas or Strange Odors: If you smell gas, leave your property immediately and call your gas company or 911. If you smell dusty or burning odors, it could be the system burning off dust (normal at first) or a more serious electrical issue.

Benefits of a Professional Heating Repair

It can be tempting to ignore a small rattle or a cold spot, but a professional repair is an investment in your safety and your property.

  • Safety & Peace of Mind: Your furnace involves natural gas, flame, and high-voltage electricity. Our certified technicians will fix the problem safely, checking for critical issues like cracks in the heat exchanger, which could leak carbon monoxide.
  • Long-Term Savings: A proper, professional fix for a worn-out part today can prevent a catastrophic, system-wide failure (and a full furnace replacement) tomorrow.
  • Restored Efficiency: A well-repaired furnace runs more efficiently. That means it uses less fuel to heat your home or business, which can help lower your monthly energy bills.
  • Warranty on Our Work: We stand by our service. Our repairs are backed by a labor guarantee, giving you peace of mind that the fix will last.

What Our Customers Say About Our
Repair Service

"I see these trucks all around town and so I gave them a call the other day. Great experience! Showed up on time, was careful parking the big truck in front of my house (tearing up grass is a common issue on my street), and SUPER fast and friendly service! Charged me a reasonable rate for a repair... Seem honest and responsible!"

Frequently Asked Furnace Repair Questions

Why is my furnace not producing any heat?
It could be a simple fix like a tripped circuit breaker or a malfunctioning thermostat. It could also be a faulty ignitor or pilot light. We'll check the simple things first.
Why is my furnace making a loud banging noise?
This can be alarming. It's often caused by dirty burners causing a delayed ignition, or your ductwork expanding. Grinding or squealing, however, often points to a motor or bearing issue.
How much will the furnace repair cost?
The cost depends entirely on what's wrong. We will always provide you with a detailed, written estimate before we start any work, so you can approve the cost.
Should I repair my old furnace or replace it?
This is the big question. We'll give you an honest answer. We use a simple guideline: if the unit is over 15-20 years old and the repair cost is high, replacement is often a smarter long-term investment. We'll show you both options, pressure-free.
