A Reliable New AC: The Best Way to Beat the Summer Heat

A new air conditioner is a critical investment for any Illinois summer. It’s not just about comfort—it’s about your property’s value, your family’s well-being, and your monthly energy bills. For a business, it’s a vital part of protecting your inventory, keeping employees productive, and ensuring customers are comfortable.

When it’s time to upgrade, you need a partner you can trust to do the job right. R.D. Davis Heating and Air Conditioning is Springfield’s 3rd-generation, family-owned AC installation contractor. We’re experts in installing high-efficiency cooling systems for every need, from a single-family home to a large commercial space, including top-tier Samsung and Tempstar® models.

Is It Time for an Air Conditioner Replacement?

It’s the big question for many property owners: is it time for another expensive repair or a full air conditioner replacement? While our team can fix most issues, here are the clear signs that a new AC installation is the smarter long-term investment:

  • Your AC is 10-15+ Years Old: If your residential or commercial unit is in this range, it’s operating on borrowed time. Modern units are significantly more efficient.
  • Frequent & Expensive Repairs: Are you calling for AC repairs every summer? If a repair bill is a large fraction of a new unit’s cost, that money is better spent on a reliable upgrade.
  • Rising Energy Bills: A sudden or steady spike in your summer electric bills is a classic sign your AC is losing efficiency, working harder, and costing you more to get the same result.
  • Uses R-22 Refrigerant (Freon): This older refrigerant is now phased out. Servicing a system that uses R-22 is extremely expensive, and it’s a clear sign your unit is obsolete.
  • Poor Performance: Your system runs constantly but just can’t keep the property cool, or it struggles to remove that sticky Illinois humidity.

The Benefits of a Modern Cooling System Installation

A new cooling system installation is more than a replacement—it’s an upgrade that pays you back all summer, every summer.

  • Lower Utility Bills: A modern, energy-efficient AC installation with a high SEER2 rating can save you 30-50% on your monthly cooling costs compared to an older unit.
  • Powerful, Even Cooling: New systems are properly sized for your home or business, eliminating the frustrating hot spots and cold spots common with older equipment.
  • Superior Dehumidification: Modern systems are far superior at removing humidity from the air, making your space feel more comfortable at a higher temperature.
  • Quiet Operation: New compressor and fan technology means you’ll barely even hear your new system running.
  • Peace of Mind: Stop worrying about breakdowns. Your new home or commercial air conditioning installation comes with a 10-year parts warranty, protecting your investment for a decade.

Our Professional AC Installation Process

A new AC unit’s lifespan and efficiency depend entirely on the quality of the installation. We follow a precise, professional process for both residential and commercial jobs.

The Consultation & Load Calculation: We don’t guess. Our team performs a professional “load calculation” that analyzes your property’s square footage, insulation, windows, and layout to determine the exact size (tonnage) you need.

The Right System Recommendation: We’ll walk you through clear, no-pressure options. Whether it’s a high-efficiency central air installation for your home or a robust rooftop unit for your business, we’ll help you find the perfect fit.

The Expert Installation: Our licensed and certified team handles everything. We’ll pull all necessary permits, safely remove and haul away your old unit, and professionally install the new system to meet all local codes.

The Custom Fit & Final Check: We test the system, check refrigerant levels, and ensure proper airflow. We’ll also show you how to use your new thermostat. For many jobs, we can even use our in-house fab shop to create custom ductwork transitions for a perfect, no-leak fit.

Frequently Asked AC Installation Questions

How much does a new AC installation cost in Springfield, IL?
The cost varies based on the system's size (tonnage), efficiency (SEER2 rating), brand, and the complexity of the installation (residential vs. commercial). We will always provide you with a firm, upfront, and transparent quote.
What size AC unit do I need for my property?
The only correct way to determine this is with a professional "load calculation." It's far more accurate than guessing by square footage. A system that's too big or too small will be inefficient, struggle to dehumidify, and wear out quickly.
Are there any tax credits or rebates available?
Yes, federal tax credits and potential local utility rebates are often available for high-efficiency, ENERGY STAR® certified units. We can help you identify a qualifying system to maximize your savings.
How long does the installation take?
A standard air conditioner replacement and installation for a home typically takes our professional team a single day. Commercial installations may take longer, but we will coordinate with you to minimize disruption.
Do I need to replace my furnace at the same time as my AC?
It is often recommended, especially if your furnace is also over 15 years old. The indoor and outdoor units are designed to work together as a "matched system" for peak efficiency and performance. We can give you an honest assessment of your furnace.
