Before you hire a professional HVAC installer, here are a few things that you should know about central air conditioning replacement costs in Denver and the overall process before starting your project.

However, the table below provided by our local Denver heating and cooling contractors will give you a good estimate of potential AC unit installation costs in the Denver, CO area :

1. AC Unit Size Matters

The measurement used for sizing your home’s air conditioners is referred to as tons. TONS is the cooling energy compared to what one ton of a melting ice block can emit in a day. According to the experts, an average Denver two-story home with about 2,000 square-foot floor area would need approximately 3 to 4 tons of air conditioning capacity. However, they also emphasize that computing for the exact tonnage requirement is vital especially with the temperature fluctuation in Denver throughout the seasons. Overestimation may make your home cool faster. However, it may hinder proper dehumidification of air, which can cause mold infestation after some time. Underestimation, on the other hand, lets your central AC unit run longer than usual, which leads to higher energy bills and faster wearing out of the appliance as well as your connected gas furnace unit

2. Check Your Current AC Ducts

If you have an existing central air conditioning system, you can have the old ducts assessed. The old ductwork may not be in the best condition, so make sure that your Denver HVAC contractor checks any potential air leaks. Leaks, even small ones, can lead up to a high 20% cooling loss. The repair costs for ducts with air leaks could be as high as $3,000, depending on if the ductwork needs to be completely replaced or simply repair. 

However, if your old AC ducts are irreparable or you don’t have existing ductowkr, you might need your contractor to install brand new ducts before the central ac unit installation. Duct installation usually takes place in the attic or basement. Then, they run within floor connections and behind cabinets and closets going from your air conditioning unit to the air blower. The cost of new ducts for a central air conditioning system in Denver can run anywhere from $2,000 to $5,000.

3. Install a Quality Central AC Filter

When installing a new central air conditioner, you’ll want to make sure your air cooling system has a high-efficiency filter. Aside from securing comfort through controlled temperature, you must also ensure that your family breathes in clean filtered Denver air. A high-efficiency filter decreases the risk of acquiring pollen and dust-related diseases.

According to Denver air conditioning contractors in our network, it is best to choose an air conditioning unit with a media filter that has a rating of 12 for its minimum efficiency reporting value or MERV. It may increase your AC unit installation cost by about $500, but it decreases maintenance costs by approximately $500 every one to two years. So it essentially pays for itself. 

Bonus Tip: Wait for the Winter Before Purchasing

An air conditioning system is just like any other home appliance. Installing an AC unit at the right time can save you a large amount of money. According to local surveys, air conditioning systems in Denver have lower prices during the winter season, so you might want to wait for the cold weather before installing a new HVAC system, if possible.

Is Central Air Conditioning Replacement Worth It?

A central air conditioner installation or replacement can add up significantly, especially if you are needing to replace ductwork, repair your furnace, or even replace a heat pump unit at the same time.

Yet, these are necessary home improvement to ensure comfort for you and your family, especially if Denver is experiencing any extreme weather conditions. It is always best to get at least four central ac installation quotes from Denver HVAC contractors before hiring one. We make it easy to find air conditioning and heating installation professionals in Denver by giving you reviews, ratings, and local feedback from neighbors in your area who have also had their HVAC systems replaced recently.
