Signs you need a new air conditioner
No single symptom settles it, but a pattern usually does. A unit that has needed several repairs in a short span, cools unevenly, runs constantly on warm days or has a rising energy bill for the same weather is telling you something.
- The unit is well into its second decade or you do not know its age.
- Repairs have become frequent, or a major part such as the compressor has failed.
- It uses an older refrigerant that is becoming harder to service.
- Some rooms never cool, even with the system running all day.
- Loud banging, grinding or squealing from the outdoor unit.
Choosing the right AC system and capacity
Capacity is measured in tons, and bigger is not better. An oversized system cools the air quickly, shuts off, and never runs long enough to pull moisture out or even out temperatures. An undersized one runs endlessly and still falls behind. A proper sizing calculation looks at floor area, insulation, windows and their direction, ceiling height, duct condition and how the house is used. A rule of thumb based only on square footage is not enough.
Efficiency is rated by SEER, and a higher number uses less electricity for the same cooling. Whether a higher rated model pays off depends on how many hours you run it and how long you plan to stay. Compare ratings, but also compare the installer plan, because ductwork matters as much as the box outside.
Other choices include single stage versus variable speed operation, which affects comfort and noise, and whether to pair the new unit with a new coil and thermostat. At our elevation, equipment should be selected and set up following the manufacturer instructions for altitude.
What happens during installation
Replacement of an existing split system commonly takes most of a day, though complex jobs run longer. Here is the usual order of work.
- Walk through the house, confirm the sizing and agree on the equipment and layout.
- Protect floors and work areas, then shut off power to the old system.
- Recover the old refrigerant properly and remove the outdoor unit and indoor coil.
- Set the new outdoor pad or unit, install the indoor coil and connect refrigerant lines.
- Connect electrical, the condensate drain and the thermostat.
- Pressure test and evacuate the lines, then charge the system to the manufacturer specification.
- Start up, measure airflow and temperature drop, and walk you through the controls.
What drives AC replacement cost
The price of a new system depends on capacity, efficiency rating, the type of equipment, how much ductwork needs repair and how hard the site is to work in. Ask for a written scope that names the equipment model, what is included and what is not. Compare any offer in writing before you decide.

Frequently asked questions
How long does an air conditioner usually last?
Many central systems run somewhere around fifteen years, though maintenance, installation quality and usage change that a lot. Age alone is not the deciding factor, but it matters when major repairs start to pile up.
Do I need to replace the furnace when I replace the AC?
Not always. The indoor coil sits on or near the furnace, and the two share the blower and ducts. The pairing needs to be compatible, so ask the installer to check whether your furnace matches the new system.
What size air conditioner does my house need?
It depends on more than square footage. Insulation, windows, ceiling height, duct condition and sun exposure all count. Ask for a load calculation instead of accepting a size guessed from the old unit.
Can I keep my existing ductwork?
Often yes, if it is sealed, insulated and sized for the airflow of the new system. Leaky or undersized ducts waste cooling, so the installer should inspect them before you decide.
When is a good time to replace an AC?
Spring or fall usually has more scheduling room than a heat wave, and you are not making a rushed choice in a hot house. If your unit has already failed, though, do not wait for ideal timing.
