Heating Installation
Our complete heating system installation and replacement workflow for furnaces, heat pumps, and hybrid systems.
A 16 SEER2 central air conditioner reduces cooling costs by 20 to 30 percent compared to a 10 SEER unit. Proper ACCA Manual J sizing prevents short-cycling that can cut lifespan up to 40 percent. Most Bayer installations finish in four to eight hours and qualify for 0 percent financing on high-efficiency American Standard equipment.
The right heating and cooling system for a Southern Illinois home depends on more than horsepower or BTU rating. It depends on the home’s age and insulation, the local climate’s swing from sub-zero January nights to 95 degree July afternoons, the homeowner’s monthly energy budget, and whether the existing ductwork is helping or hurting performance. The Bayer family has been making these calls in Williamson and Franklin counties since 2021, and the answer is rarely the most expensive option in the catalog.
We install, replace, repair, and maintain heating and cooling systems across our 100 square mile service area. Steve Bayer was trained by Mike Holland to size systems by ACCA Manual J load calculation rather than by rule-of-thumb square footage, because an oversized system short-cycles, wears out faster, and runs higher utility bills. We service all major brands and specialize in American Standard equipment, including their inverter driven heat pumps, two-stage condensers, and high-AFUE gas furnaces.

Our complete heating system installation and replacement workflow for furnaces, heat pumps, and hybrid systems.

AC and heat pump cooling system installation, including condenser-only swaps and full split-system replacements.

Diagnosis and repair for ducted and ductless heat pumps, the highest-growth equipment category in Southern Illinois.

Scheduled tune-up programs for residential and light commercial systems that run more efficiently and last longer.
We measure your home’s actual heating and cooling load based on square footage, insulation R-values, window area and orientation, infiltration rate, and occupancy. We do not size by rule of thumb.
We discuss your monthly energy budget, your fuel options, and your replacement timeline. We specialize in American Standard equipment but install other brands when that is the right call.
Most residential installations complete in four to eight hours. We follow manufacturer torque specifications, vacuum the line set to 500 microns, and verify charge by superheat or subcooling.
We show you the new equipment, walk through the thermostat, hand off the warranty paperwork, and schedule the first maintenance visit.

Most residential installations complete in four to eight hours, depending on system type and any ductwork modifications required. A like-for-like furnace or AC replacement is typically a same-day job. We will give you an honest timeline before we start.
Yes. We specialize in American Standard products but we install other major brands when that is the right call for your home and budget. We are not a single-brand dealer.
SEER2 is the current Department of Energy efficiency rating for cooling equipment, replacing the older SEER scale as of January 2023. A 16 SEER2 unit performs roughly equivalent to a 17 SEER unit on the old scale.
Modern cold-climate heat pumps work well here. An inverter-driven heat pump is a strong primary system for most homes, and a hybrid setup with a gas furnace is often the best economic answer.
Twice a year for most systems, once before cooling season and once before heating season. Ask about our maintenance plan when you call.
Call (618)944-1463 or contact us online to schedule a no-pressure system assessment. The Bayer family will measure your home, talk through your budget and goals, and explain your options before recommending any equipment.
