Installation
Signs it may be time to replace
- The system is 12 to 15 years old or more
- Repairs are getting more frequent
- A major part has failed, such as the compressor or heat exchanger
- Energy bills keep climbing
- Some rooms never get comfortable
- An older air conditioner still uses R-22 refrigerant, which is no longer produced
Three things to do before you decide
- Find the age. The manufacture date is usually on the unit's data plate.
- Add up what you've spent on repairs in the last two years.
- Compare the repair quote with a replacement quote before you commit to either.
Checked those and it’s still acting up? Call or text (573) 797-5242.
What we replace, and what matters
Air conditioners
Central air conditioners for homes and light commercial buildings.
Furnaces
Furnace replacements, sized to the house.
Heat pumps
Heat pump replacements for year-round heating and cooling.
The right size
A system that's too big short-cycles and leaves the house humid. One that's too small never catches up. The right size depends on the house, not just the label on the old unit.
The installation
Even good equipment performs poorly when it's installed carelessly. The install is where a new system earns or loses its efficiency.
The ductwork
A new system on leaky or undersized ducts won't deliver what it should. We repair ductwork too.
Repair or replace?
Not every old system needs replacing. If yours is under 12 years old and the repair is minor, repair usually wins. If it's older and facing a major repair, a replacement quote is worth having before you decide.

Questions
Fair questions, straight answers.
Should I repair or replace my system?
As a rough rule, if the system is 12 to 15 years old and facing a major repair, compare a replacement quote before you spend on the repair. Younger systems with minor problems are usually worth fixing.
Can you replace just the AC or just the furnace?
Often, yes. The indoor and outdoor parts of a cooling system are designed to work as a matched pair, so it depends on your setup. Call or text and we'll take a look.
Do you replace heat pumps?
Yes. We replace air conditioners, furnaces, and heat pumps.
