IS IT TIME FOR A NEW AC?

Signs Your Livonia Home Needs a New Air Conditioning System

Most central AC systems last 15 to 20 years. If yours is approaching that range, or showing any of the signs below, replacement is almost always the better investment over continued repairs.

Age over 15 years

Older AC systems lose efficiency significantly as they age. Modern units run at SEER2 ratings that older systems can't match, lower operating costs every summer for the life of the new system.

Rising coolong bills

If your electric bill climbs each summer without a change in usage, your system is working harder than it should. An aging compressor or refrigerant leak will continue to drive costs up.

Frequent Repairs

One service call every few years is normal. Multiple repairs in a single cooling season signals the system is at the end of its serviceable life, repair costs compound fast.

Uneven Cooling

Some rooms comfortable, others stuffy and hot, a sign the system can no longer distribute cooled air effectively, often due to an undersized or failing compressor.

Runs Constantly

An AC unit that runs all day without reaching your set temperature is either undersized, losing refrigerant, or failing internally. None of these get better with time.

Uses R-22 Refridgerant

R-22 (Freon) has been phased out and is now expensive and scarce. If your system uses R-22, replacement with a modern R-410A or R-454B system is far more cost effective than continued repairs.

SYSTEM OPTIONS

Central AC Systems We Install in Livonia

We install central air conditioning systems from all major manufacturers. Every recommendation is based on a load calculation for your specific home, not a guess based on square footage alone.

Most Common

Central Split System

The standard for most Livonia homes, an outdoor condenser paired with an indoor air handler or coil connected to your existing furnace and ductwork. Most cost effective option for homes that already have ducts.

Heat Pump System

A heat pump provides both cooling in summer and heating in winter from a single outdoor unit. Increasingly popular for Livonia homeowners looking to reduce energy costs or replace aging equipment on both sides.

High-Efficiency AC

Units with SEER2 ratings of 17 or higher deliver significantly lower operating costs over time. Best for Livonia homeowners planning to stay long-term and wanting to minimize summer energy bills.

WHAT AFFECTS THE COST

What Determines AC Installation Cost in Livonia

Central AC installation costs vary based on several factors specific to your home. We don't publish flat rates because a quote without seeing your property isn't accurate, it's a guess.

System Size & Efficiency Rating

Higher SEER2 ratings mean lower operating costs over time. For Livonia homes running AC four to five months a year, the efficiency premium often pays back within a few seasons.

Home Size & Layout

Square footage, ceiling heights, sun exposure, insulation quality, and window area all factor into the load calculation that determines the right system size for your home.

Existing Ductwork Condition

If your existing duct system is in good condition it can typically be reused. Leaky, undersized, or damaged ducts that need repair or replacement add to the overall project cost.

Equipment Brand & Model

We install multiple brands at different price points — from reliable mid-range options to premium efficiency units. We'll match the right equipment to your budget and goals.

The only way to get an accurate number is a free on-site estimate. We'll assess your home, run the load calc, and give you a written itemized quote, no obligation.

Replacing Your Furnace Too?

If your furnace is also aging, replacing both systems at the same time often makes sense, matched systems run more efficiently together, installation costs are lower when done simultaneously, and you won't be scheduling another install in two years. We'll assess both units during your estimate and give you an honest recommendation.

AC Installation Questions — Livonia, MI

Everything Livonia homeowners ask before scheduling their AC installation estimate.

How long does central AC installation take in Livonia?

Most residential central AC installations in Livonia are completed in a single day. If duct modifications are needed or it's a more complex installation, it may extend into a second day. We'll confirm the timeline before scheduling.

Do I need a permit to install central AC in Livonia?

Yes. The City of Livonia requires a mechanical permit for central air conditioning installations. We handle the permit application and coordinate the required inspection as part of our standard process — it's included at no additional charge.

What size AC unit does my Livonia home need?

We run a Manual J load calculation on every job to determine the correct system size. This accounts for your home's square footage, insulation, windows, ceiling height, and sun exposure. An oversized unit will short-cycle and leave your home humid; an undersized unit will run constantly and never keep up. Correct sizing is one of the most important parts of the installation.

Can I use my existing ductwork with a new AC system?

In most cases, yes — especially if your existing ducts are in good condition and were properly sized for your home. We inspect the duct system during your estimate and let you know if any modifications are needed before we recommend a system size.

What SEER2 rating should I choose for a Livonia home?

Michigan's cooling season runs roughly May through September — about five months of meaningful AC use. At that usage level, stepping up to a higher SEER2 unit typically pays back in energy savings within a few seasons. We'll show you the estimated operating cost difference between options during your estimate so you can make an informed decision.

Should I replace my AC and furnace at the same time?

If your furnace is also aging, replacing both together usually makes financial and practical sense. Matched systems from the same manufacturer often run more efficiently together, installation labor is lower when done at once, and you avoid scheduling a second install a year or two later. We'll give you an honest assessment of both systems during your estimate.
