An old AC can limp along for years. Then one hot week, it stops cooling the house. Or the repair bills start to add up. That is often the moment to ask whether a new system makes more sense.
Motortreaty Heating & Air is a referral service. We do not install anything. We connect homeowners in the Austin area with independent providers in our network. A provider can look at your home, talk through your options, and give you a written quote. You decide what happens next. Less searching, more cooling.
Is it time for a new AC?
Maybe your AC still runs, but the house never feels cool. Or the repair bills keep coming back. Both can point to replacement. It helps to find out before the heat peaks.
A provider in our network can look at the system and explain whether repair or replacement fits your home. You stay in charge of the choice.
Signs your AC may need replacing
No single sign decides it. Look for a pattern.
- The system is around 12 to 15 years old, or older.
- Repairs are getting more frequent.
- Rooms stay warm even when the AC runs all afternoon.
- The air feels sticky indoors.
- Power bills climb with no change in how you live.
- You hear grinding, rattling or loud buzzing.
- The unit uses an older refrigerant that is harder to find now.
If the AC has stopped completely in a heat wave, Emergency AC repair may be the first step. A provider can tell you if a fix is worth it or if the unit has reached the end of its life.
Why our summers are tough on equipment
Long, hot, humid seasons mean the AC works hard for many months. Attics in many homes get extremely hot, which adds to the load. Storm season brings power surges and heavy rain around the outdoor unit. All of this wears a system down faster than a mild climate would.
Mild winters are easier on the equipment, but they do not give it much rest between seasons.
Timing the work with the seasons
Spring and early fall are usually calmer times to plan a bigger job. Schedules are often fuller in peak heat, when many homes need help at once. Reach a provider early, and you have more room to compare options and ask questions.
A new system can still be set up in summer. The point is simply to avoid choosing in a rush.
Types of cooling systems
Providers in our network may talk about a few common setups:
- Split central system. An outdoor unit plus an indoor coil and air handler. This is the most common type for houses with ducts.
- Heat pump. One system that cools in summer and heats in winter. It suits places with mild winters.
- Packaged unit. All parts in one outdoor cabinet, often on a pad or roof.
- Ductless mini-split. Good for additions, garages, or older pier-and-beam houses where adding ducts is hard.
Some homeowners also search for furnace replacement near me while they plan a new AC. If your heating and cooling are both aging, ask the provider about the whole setup. A furnace or air handler often needs to pair well with the new AC.
Why proper sizing matters
Bigger is not better. An oversized unit cools the air fast, then shuts off. That short cycling leaves the house damp and clammy. An undersized unit runs nonstop and still falls behind on hot afternoons.
Ask the provider to measure your home and calculate the load. Do not just copy the size of the old unit. Brick or vinyl siding, attic insulation, window size and shade all change the answer.
What an AC installation includes
The scope depends on your home, but a typical job may include:
- Removing the old unit and safely recovering the refrigerant.
- Setting the new outdoor unit on a level pad.
- Installing the indoor coil and connecting the refrigerant lines.
- Checking the electrical connection and the condensate drain.
- Setting up the thermostat.
- Testing airflow, cooling and safety controls.
- Handling permits where your area requires them.
Ask for these items in writing, so you can compare quotes fairly.
Matching the system
The outdoor unit, indoor coil and air handler should be made to work together. Mismatched parts can cut performance and shorten the life of the system.
The ducts matter too. Leaky ducts in a hot attic waste cool air before it reaches the rooms. A provider may suggest sealing or repairing them during the job. Also ask whether your current thermostat works with the new equipment.
Efficiency in plain terms
Efficiency is shown by a SEER2 rating. A higher number means the system uses less power to make the same cooling. In a long summer, that can add up on your power bill.
Still, a higher rating also costs more up front. The payoff depends on how much you run the AC. Ask the provider to explain the tradeoff for your home. It is also smart to check with your utility about any rebates.
Questions to ask the provider
- Will you measure the home to size the system?
- What brand and model are you proposing, and what is the efficiency rating?
- What is included in the written quote, and what is not?
- Are permits and old-unit removal part of the price?
- What does the warranty cover, and who handles claims?
- Should the ducts be checked or sealed?
- How long will the job take?
