The size is a significant determinant since it dictates how much cooling capacity you’ll need, which in turn impacts the type and size of equipment required. The smallest and least expensive type of air conditioner is a window unit. All of the system’s components are housed in a single unit, which is meant to sit in an open window sill so it can vent heat outdoors.

In other areas like the Hollywood Hills, Westlake and Koreatown, rent runs closer to the city’s average. One-bedrooms across these three neighborhoods averages between $2,510 and $2,800. While living in La La Land will cost you 51.9 percent more than the national average, roughly 4 million people living in this desert oasis make it work — and so can you. Especially if you are willing to spend extra money on a premium brand name AC unit, such as Carrier, don’t try to squeeze a few hundred dollars of savings by hiring a sub-par installer. The best course of action is to hire a licensed installer who has a comprehensive, professionally designed HVAC calculator.
Window or portable AC unit
The labor cost to install central air conditioning is $1,500 to $2,500 or more, depending on if it includes new ductwork. Installing central air conditioning for a 1,200 square foot house costs $2,500 to $6,000. Central air for a 2,000 square foot home costs $3,100 to $7,800+.
HVAC replacement – central heat and air unit
There are two types of Manual J calculations ( whole house and room by room) and your contractor will decide which one is best to do, depending on your particular situation. You don't need to tip HVAC installers unless they exceed your expectations. Consider tipping if the installers worked in extreme heat or cold or completed the project sooner than expected.
Do You Need Ductwork Replacement?
If the project type is “New Construction”, the calculator includes cost of installing new copper lines between outside compressor and inside coil (air handler). Electrical connections are responsibility of the owner, since when you are building a new home, you typically have an electrician doing all the electric work. In reality, it is possible to install central air in the majority of homes, even old ones, that don’t have any ductwork. Many people are worried about the potential challenges as well as the high costs of this upgrade.
High-efficiency systems have higher SEER ratings—usually 18 or above. Some maximum-efficiency air conditioners have a SEER rating of up to 24. In general, however, the larger your home, the more BTU’s of cooling power you need, but other factors including climate and your home’s layout also matter. In persistently hot areas of the country, 1 ton of capacity is recommended for every 500–600 square feet of home. Size down if you live in a cooler climate or if your home has better than average insulation — unless you plan to build an addition in the near future.

Apartment buildings often need to have built-in ducts from the start. The ducts need to travel through the entire building, and it is more cost-effective to do multiple units simultaneously than to add it to a single unit. These spaces are subject to moisture due to condensation if they are added after the building was built. The cost of a Lennox central air conditioner averages $4,000 to $7,150 for a 3-ton unit. Lennox specializes in all types of heating, cooling, and ventilation products.
Adding a central air conditioner requires a permit and a safety inspection in most areas to ensure it meets building code. This central ac unit cost estimator will provide you with up to date pricing for your local area. For example, a 2,000-square-foot home would require 36,000 BTUs to cool it. Dividing 36,000 by 12,000 equals 3, so this home would require a 3-ton AC unit. Air conditioning is considered a necessity in most regions where temperatures can soar during the summer months. Before we provide details for both retail equipment costs and installed costs, here are a few common home sizes and the cost to replace central air for them.
Central AC Installed Cost
Homeowners in 2,000 square foot homes in the middle of the country pay an average of $6,800 to $8,400 to replace central air when hiring a certified technician. A heat pump can cool in the same way but can also reverse itself to provide heat instead when needed. Air conditioners are typically paired with a furnace to heat the home during cold months. An air conditioner warranty lasts 10 to 15 years if the product is registered within 60 days of installation. Coverage timeframes for individual parts vary from 5 to 20 years, depending on the brand.
Various factors, including ceiling height and how well-sealed the home is, can impact this estimate. In general, a 1-ton AC unit can cool 500 to 600 square feet of space. That means you’ll need 12,000 BTUs for every 500 to 600 square feet of living space. If your home has high ceilings, multiply the tonnage you need by 1.25. While your mini split equipment may not look as attractive as invisible central air, you need to consider that you have a significant loss energy in the ducts of a central air system. Another major benefit is that a mini split AC system can be installed DIY, which is not possible with central air.
Available in sizes from 8000 to 18,000 BTUs and higher, prices range from $399 to $800 depending on size and features. Most, but not all, also dehumidify, and some can function as heaters. Single-stage air conditioners turn on frequently — and because most of their power draw occurs during start-up, they’re more expensive to operate. Single-stage air conditioners turn on when the indoor temperatures exceed the setting on your thermostat. If you set the thermostat to 70 degrees, the air conditioner will run whenever the indoor temperatures reaches 71 degrees.
