A Reliable New Furnace: Your Property’s Most Important Upgrade

A new furnace is a major investment in your property’s safety, comfort, and value. For a homeowner, it means peace of mind on a cold night. For a business owner, it means a safe, comfortable environment for your employees and customers.

We understand that you’re not just buying a piece of equipment; you’re investing in a long-term solution. R.D. Davis Heating and Air Conditioning is Springfield’s 3rd-generation, family-owned heating installation contractor. We provide honest, no-pressure estimates for both residential heating installation and commercial-grade systems. We’re proud to be authorized dealers for Tempstar® furnaces, known for their reliability and performance.

Is It Time for a Furnace Replacement?

It can be tough to know when to repair an old furnace versus investing in a full furnace replacement. Here are the key signs that a new heating system installation is the smarter financial choice for your home or business:

  • Your Furnace is 15+ Years Old: Most furnaces have a lifespan of 15-20 years. An older unit is operating on borrowed time and likely costs you a fortune in lost efficiency.
  • Frequent & Expensive Repairs: Are you calling for repairs every winter? If a repair bill is a significant fraction of a new unit’s cost, it’s time to upgrade.
  • Rising Energy Bills: A sudden or steady spike in your utility bills is a classic sign your furnace is losing efficiency and working much harder to produce the same amount of heat.
  • Uneven Heating: Are some rooms or offices freezing cold while others are too hot? This can be a sign of an aging, struggling system or (just as often) failing ductwork.
  • Loud Noises or Visible Cracks: Banging, grinding, or whistling sounds, as well as any visible rust or cracks on the unit, are serious warning signs that a catastrophic failure could be near.

The Benefits of a Modern Heating System Installation

A new, professionally installed furnace isn’t just a replacement—it’s an upgrade that pays you back in lower costs, higher comfort, and total peace of mind.

  • Lower Utility Bills: A modern, high-efficiency (90%+ AFUE) furnace can save you 30% or more on your heating bills compared to an older, 10-15 year old model.
  • Total, Even Comfort: New systems provide consistent, reliable heat, eliminating the cold spots and drafts common with older units.
  • Quiet Operation: Modern furnace blowers are designed to be whisper-quiet, so you’ll feel the comfort, not hear the noise.
  • Better Indoor Air Quality: A new system with a clean blower and advanced filter options provides cleaner, healthier air for your family or employees.
  • Peace of Mind: A new heating unit installation service comes with a new warranty, meaning you’re covered for both parts and labor, eliminating the worry of another unexpected repair bill.

Our Professional Furnace Installation Process

A perfect installation is more than just swapping boxes. It’s a precise, professional process that guarantees your new system will perform efficiently for years to come.

The Consultation & Load Calculation: We don’t guess your furnace size based on square footage alone. We perform a full “load calculation” (as mentioned in our FAQs) to find the perfect size for your home or business, factoring in insulation, windows, and layout.

The Right System Recommendation: We’ll show you the best options for your needs and budget, from high-efficiency Tempstar® systems to gas or electric models, and provide a clear, no-pressure quote.

The Expert Installation: Our licensed team handles everything. We’ll pull all necessary permits, safely remove and haul away your old unit, and professionally install the new one, connecting all gas, electrical, and ventilation lines to code.

The Custom Fit & Final Check: This is where we test the system, check airflow, and show you how to use your new thermostat. For many installations, we use our custom fab shop to create perfect ductwork transitions, ensuring a seamless, no-leak fit.

What Our Customers Say About Their
New Installation

We’re proud of our work, and we’re even prouder of the trust our customers place in us.

"We have two furnaces and ac units bought from RD Davis. Roger came out a few years ago to place the second AC. He had to crawl trough mud on our crawl space and never complained! He has also replaced... the hot water heater at my mother in laws home at a fraction of what it would have been elsewhere. Saved her over $1000. Highly recommend!"

- Tanya F.

"Appreciate Roger and his crew for installing our new AC and Furnace! Very friendly and professional and did great work!"

Frequently Asked Heating Installation Questions

How much will a new furnace installation cost in Springfield?
The cost for a new furnace installation depends on the system's efficiency (AFUE rating), size (BTU), and the complexity of the job. We'll provide you with a firm, upfront quote with no hidden fees.
What size furnace do I need for my home or business?
The only way to know for sure is with a professional "load calculation." Our team will assess your property's insulation, windows, layout, and more to determine the exact size you need. A system that's too big or too small will be inefficient and wear out quickly.
How long does the installation process take?
Most residential heating installations are completed in a single day. More complex commercial jobs or installations that require new ductwork may take longer, but we will always communicate the timeline clearly.
What kind of warranty do you offer?
Your new system comes with a manufacturer's warranty (often 10 years on parts) plus our own R.D. Davis labor warranty that guarantees our installation work. We stand by our craftsmanship.
