What air conditioning installation & replacement involves
A proper AC installation includes load calculation, matched coil and condenser, correct lineset and charge, duct and static pressure evaluation, a properly pitched condensate route with a safety switch, and commissioning readings at the end.
Central air replacement matched to your ductwork and your house, with a real load calculation behind it.
Common problems and warning signs
- Coil leaks that keep coming back
- Original builder equipment reaching end of life
- Ductwork that needs work anyway — do both together
- Planning replacement in the off-season instead of during a failure
- You want humidity control, not just temperature
How we repair it
If the compressor is sound and the coil isn't leaking, repair is usually the better value, and we'll tell you so.
When replacement makes sense
Installs include correct evacuation and charge, new pad and disconnect where needed, condensate safety switch, thermostat setup and a walkthrough before we leave.
