Heating and Cooling for Decatur's Historic and Mid-Century Homes Since 2003
Most HVAC breakdowns start with small warning signs, like a new noise or a system that takes longer to reach the set temperature. Each symptom below usually means one part is failing, and an early repair can keep that part from damaging the rest of the system.
| Symptom | Likely Cause | What We Check |
|---|---|---|
| The AC blows warm air | Low refrigerant or a failing compressor | Refrigerant charge and compressor operation |
| The furnace flame burns yellow instead of blue | Incomplete combustion, which can carry a carbon monoxide risk | Burner condition, venting, and a carbon monoxide check |
| The system does not respond after adjusting the thermostat | An electrical fault or a failed control board | Thermostat wiring and control board function |
| A musty smell comes through the vents when the system runs | Moisture in the ductwork or on the evaporator coil | Coil condition and duct moisture |

Millikin Place holds some of Decatur's best-known early-1900s homes, including the 1911 Edward P. Irving House designed by Frank Lloyd Wright. Ductwork in homes of that age was often added well after the original construction, which can leave airflow that never quite matches the floor plan.
Most of Decatur's remaining homes were built during the city's mid-century growth years. Original or first-replacement equipment from that era is frequently at or beyond a typical 15- to 20-year service life, so age itself becomes part of the diagnosis.

An HVAC visit can easily turn into a bigger job than the problem requires. We build our process the other way, so you see the failed component itself before anything gets approved.
| What Matters to You | Edelman | Other HVAC Providers in Decatur |
|---|---|---|
| Knowing what actually failed before paying for parts | We confirm the specific component during the diagnostic visit before recommending a repair | Some providers recommend parts from symptoms alone, which can leave the real problem in place |
| Seeing a price before work starts | Every repair is quoted in writing, with the $139 diagnostic visit credited toward the total when you approve it | Diagnostic charges and estimates vary by provider, and not every provider credits them toward the repair |
| Getting help when temperatures turn extreme | No-heat and no-cool calls move to the front of the schedule | Emergency scheduling varies from provider to provider |
| Knowing who is working on your system | Every technician is NATE-certified and explains what they find in plain language | Certification requirements vary, and an unclear explanation leaves you unsure whether anything was fixed |
Service Process
Every Decatur HVAC call follows the same steps, whether the system is original to a Millikin-area home or a newer installation across town. You will know the cause and the cost before any repair begins.
Step What We Do
We ask what the system is doing, how long it has been happening, and whether it involves heating or cooling
A NATE-certified technician inspects the equipment, ductwork, and controls, and confirms the $139 diagnostic fee
We identify the specific component or condition causing the problem
You see the repair plan and price in writing, with the diagnostic fee credited toward the total if you move forward
Once you give the go-ahead, we complete the repair with equipment already stocked on the truck whenever possible
We run the system through a full heating and cooling cycle, confirm it holds the set temperature, and answer any remaining questions
We keep priority scheduling open for no-heat and no-cool emergencies, and most Decatur appointments are same-day. When temperatures turn extreme, a home with no working system moves to the front of the line.
We always do. After the initial diagnostic visit, nothing happens until you see the price in writing and approve it.
The fee covers your technician's time to inspect the system and identify the exact failure. If you approve the recommended repair, we credit that $139 toward the total cost, so you don't pay for the same visit twice.
We will show you the specific part or condition that failed and explain why replacement may make more sense, particularly on a system already past the typical 15 to 20 year mark. The decision stays yours, and we will not push a full replacement when a repair can reasonably hold.
The Home Wellness Club ranges from $18 to $72 per month depending on the options you choose. Membership includes annual tune-ups, a waived dispatch fee on repair work, waived after-hours surcharges, and 20% off every repair. Members also receive special warranties and parts and labor guarantees available only through the club.
Financing is available based on credit approval, and we work with multiple finance partners to get you the best rate.
A repair only holds up if it targets what actually broke. Whether your Decatur home still runs equipment original to a Millikin-area house or a system installed during the city's mid-century growth, we confirm the cause first and price the fix before you approve anything.
