AC Installation and Replacement
Request an estimate today
An air conditioner that is old, loud or always breaking down can drain your budget one repair at a time. When the numbers stop adding up, a new system may be the smarter buy. This page explains how replacement works, what shapes the price, and how to compare your options before you agree to anything.
Lieaddition Heating & Air is a referral service. It does not install equipment. Instead, it connects you with independent local providers in our network who handle HVAC service, from sizing the unit to setting it up and testing it. Request an estimate, compare written quotes, and decide in your own time. There is no obligation, and you can ask as many questions as you like along the way. Your home, the humidity and your budget all matter, so the right choice looks different for every house.
Repair or replace? Start with the math
A cooling system that fails often is a budget problem, not just a comfort problem. Each repair adds to the total. At some point, that money is better spent on a new unit.
Many providers use a simple rule. Multiply the repair price by the age of the system in years. If the result is bigger than the price of a new unit, replacing may make more sense. It is only a rule of thumb. A written quote will tell you far more.
Signs your AC may need replacing
Look for patterns, not one bad afternoon.
- The system is 12 to 15 years old, or older
- Repairs keep coming back, season after season
- Power bills climb while your habits stay the same
- Some rooms stay warm while others feel fine
- The unit runs for hours and the air still feels sticky
- You hear banging, grinding or squealing
- The system uses an older refrigerant that is getting harder to find
In a humid climate, a cooling system works hard for most of the year. That wear adds up faster than it does in milder places.
If it quit in the middle of a heat wave
When the house gets hot, you want relief fast. Emergency AC repair may be the first step, because a provider can tell you on site whether the unit is worth fixing. Many providers can respond quickly, though availability varies. Request a callback to check provider availability, or send a request and see who replies.
Try not to let the heat rush you into a bad deal. Ask for the repair price and the replacement price in writing, side by side. Compare, then decide.
Types of cooling systems
The right type depends on your home. Here are the common ones.
- Split system. An outdoor unit plus an indoor coil and air handler. This is the usual setup in block homes with an attic or closet unit.
- Heat pump. Cools in summer and heats in winter. It suits places with mild winters.
- Package unit. All parts sit in one outdoor cabinet. It is common beside condos and townhomes, or on a roof.
- Ductless mini-split. No ducts needed. It works well for additions, garages or homes with no ductwork.
If your heating is also aging, a search like "furnace replacement near me" may lead to a bigger plan. Ask the provider whether doing both at once cuts labor costs. Heating and cooling parts often share ducts and controls.
Why proper sizing matters
Bigger is not better. An oversized unit cools the air quickly and then shuts off. It never runs long enough to pull moisture out, so the house feels clammy. It also starts and stops often, which wears parts faster.
An undersized unit has the opposite problem. It runs all day and still falls behind.
A careful provider looks at square footage, windows, insulation, roof type, shade and ducts. Be wary of any quote that simply copies the size of the old unit.
What an installation includes
Scopes differ, so ask what is in the price. A typical job covers:
- Removing and disposing of the old unit
- Setting the new outdoor unit on a level pad
- Connecting the indoor coil or air handler
- New refrigerant lines where needed
- Electrical connections and a safety disconnect
- A thermostat that works with the new system
- A condensate drain line and a safety switch
- Startup, testing and a walk-through
- Permits, where your area requires them
Matching the system
The outdoor unit and indoor coil should be a matched pair. A mismatch can cut efficiency and shorten the life of the equipment.
Check the ducts too. Leaky or crushed ducts waste cool air, no matter how new the unit is. Ask whether sealing or replacing them would help.
In storm-prone areas, ask how the outdoor unit will be secured and whether the pad sits high enough to stay clear of water.
Efficiency in plain terms
Cooling systems carry a SEER2 rating. A higher number means less power used for the same cooling. Higher-rated units usually cost more up front.
Where cooling runs most of the year, the extra cost can pay back sooner. Ask each provider to show the estimated yearly running cost for two models. Also check with your power company about rebates, since some offer them.
Comparing quotes without pressure
Get two or three quotes in writing. Ask each provider to quote the same scope, so you can compare like with like. Look at the unit model, the efficiency rating, the warranty terms, what is included and what is not.
A price far under the others deserves a question. So does a price far above them. A good provider explains the numbers calmly and gives you time.
Questions to ask the provider
- How did you decide on this size?
- Is the old unit worth repairing at all?
- Which parts are covered by the manufacturer warranty?
- Is labor warranty offered, and for how long?
- Do the ducts need work?
- Will you pull the permit?
- How long will the job take?
Plan ahead when you can
A planned replacement usually costs less than a rushed one. You have time to compare, and providers are not juggling a rush of breakdown calls. Small problem, smaller bill.
