AC Installation and Replacement for Homeowners

Some air conditioners can be fixed. Others have reached the end of their useful life. This page helps you tell the difference, using plain words and a few simple comparisons. You will see the common signs of a worn-out system, the main types of cooling equipment, and why the size of a new unit matters so much.

Closestroughly Heating & Air is a referral service. It does not install or repair anything. After you send a request, Closestroughly Heating & Air connects you with an independent local provider in its network. That provider looks at your home, explains your options, and gives you a written estimate. You decide what happens next, with no obligation. Explained before estimated is how this site works.

Repair or replace? Start with this question

If your cooling quit on a hot afternoon, one question comes first. Is this a small fix, or is the whole unit finished? Think of an older car. A new battery makes sense. A new engine in a car with 200,000 miles often does not.

A local provider can check the age of the system, its repair history and the part that failed. Then they can lay out both paths in writing. Closestroughly Heating & Air does not do this work. It connects you with an independent provider who does.

When the AC stops during a heat wave

Long dry seasons bring long hot stretches. If the unit has stopped completely, ask the provider about emergency AC repair first. A short repair can get you through the worst heat while you plan a replacement without pressure. Many providers can respond quickly, though availability varies by day and by company.

Request a callback to check provider availability, or send the request form and describe what is happening.

Signs your AC may be at the end of its life

One sign alone may not mean much. Several together usually tell a clearer story.

• The system is about 12 to 15 years old, or older.
• Repairs keep coming back, season after season.
• Some rooms stay warm while others feel fine.
• Energy bills climb, though you use the AC the same way.
• The unit runs for hours and the house never feels cool.
• You hear grinding, buzzing or loud clanks.
• The system uses an older refrigerant that is getting harder to find.

Why proper sizing matters

Buying an air conditioner is a bit like buying shoes. Too big and too small both cause trouble. An oversized unit cools the air fast, then shuts off. The house feels clammy, and the parts wear out from starting and stopping. An undersized unit runs nonstop and still falls behind.

A careful provider measures the home first. They look at square footage, windows, insulation, sun exposure and the ducts. Be cautious if someone simply matches the old unit's size. The old one may have been wrong, or your home may have changed since it was put in.

Types of cooling systems

Each type suits a different kind of home, the way a pickup, a sedan and a bike suit different trips.

• Split central system: an outdoor unit plus an indoor coil, sharing your ducts. This is the most common setup.
• Heat pump: cools in summer and heats in winter. Mild temperatures near the coast can suit it well.
• Ductless mini-split: a small outdoor unit feeding wall-mounted heads. It works where there are no ducts, such as additions or older bungalows.
• Packaged unit: all parts in one outdoor cabinet, set on a pad beside the house or on the roof.

Matching the system to your home

Stucco ranch homes on slabs often have the air handler in the attic or a hall closet, with ducts running through a very hot attic. Homes on raised foundations may have ducts in the crawl space. Many 1950s to 1980s tract homes have ducts that leak or were sized for older equipment.

A new AC on tired ducts is like a new faucet on a leaky pipe. Ask the provider to check the ducts and tell you what they found. Also ask that the indoor and outdoor parts be rated to work together.

Some homeowners with an old furnace start searching furnace replacement near me while they plan a new AC. That topic has its own page here. It is still fair to ask the provider how the two pieces of your heating and cooling setup fit together.

What an installation usually includes

Details differ from job to job. Most written estimates cover steps like these:

• Removing the old unit and safely recovering its refrigerant
• Setting the new outdoor unit on a level pad or mount
• Connecting the refrigerant lines, drain line and electrical disconnect
• Fitting the new indoor coil or air handler
• Wiring the thermostat
• Pulling permits where your area requires them
• Starting the system and testing airflow and refrigerant levels

If any of these are missing from the estimate, ask why.

Get Started

Efficiency in plain terms

An efficiency rating, often shown as SEER2, works like miles per gallon. A higher number means the unit uses less electricity to deliver the same cooling. Where summers are mild near the coast, the AC runs fewer hours, so a very high rating may take longer to pay off. In hotter inland areas, it can pay off sooner.

Ask the provider to show two or three options with their ratings and prices side by side. Utility programs sometimes offer rebates, so ask if any apply.

Smoke seasons and indoor air

Wildfire smoke can clog filters quickly. A filter is like a coffee filter. When it gets full, air struggles to pass through and the system works harder. If smoke is a concern, ask the provider about a thicker filter slot or other air cleaning options. Also ask how often the filter should be changed.

Questions to ask the provider

• How did you decide on this size?
• Will you check my ducts, and what did you find?
• Which brands and models are in the estimate?
• What warranty comes with the equipment and with the labor?
• Does the price include permits and removal of the old unit?
• When could the work start, and how long will it take?
