The Cost of a New Air Conditioner in Houston, TX

Houston, TX, is renowned for its hot, humid climate, with around 100 days each year reaching 90°F or higher. After a few hours in the blazing sun, nothing feels better than stepping into your home and enjoying the crisp, cool air from your AC.

But if your air conditioner is old, inefficient, or frequently breaking down, it may be time to consider a replacement. That way you won’t find yourself sweating it out with a broken AC on one of the hottest days of the year. Naturally, you’re probably wondering how much an AC unit costs in Houston, TX. We have the answers.

Average Cost of an AC Unit in Houston

The cost of buying a new AC, including professional installation, can vary based on several factors we’ll detail in a bit. But on average, expect to pay the following:

• 3-ton AC Condenser + Air Handler: $9,500 to $12,500
• 3-ton AC + Furnace System: $10,500 to $13,500

What Factors Affect the Cost of a New Air Conditioner?

Air conditioners aren’t a one-size-fits-all solution. Factors that play a role in the final cost include:

Capacity

The pricing above is for a 3-ton AC unit, which is typically suitable for a 1,500-2,000-square-foot home. A 3-ton system costs more than a 2-ton unit, for example, but less than a 4- or 5-ton system.

Although square footage plays a substantial role in your AC’s size, other factors such as your climate zone, ductwork, insulation quality, and number of windows also factor into the equation. A licensed HVAC professional should perform an HVAC load calculation which takes all these factors into account when determining the correct size.

Efficiency Rating

Homeowners in southern states like Texas are required to have an air conditioner with a SEER2 rating of at least 14.3 (equivalent to 15 SEER). ACs with higher SEER ratings cost more but deliver lower energy costs. However, if you’re on a budget, even the minimum rating of 14.3 is still considerably more efficient than systems manufactured just over 10 years ago.

Brand and Warranty

The cost of a new air conditioner in Houston can vary greatly depending on the brand. If you're looking to save money, a budget-friendly option might be suitable for you. However, some brands are more expensive because they are known for providing higher quality, more reliable systems, and stronger warranties.

Motor Technology

When shopping for a new HVAC system in Texas, you’ll also be given options for systems with single-stage, two-stage, and variable-speed motors. It’s important to know the differences and how they might affect the price.

• Single-stage ACs run at full blast while cooling. They are the most affordable option, but also the least efficient.
• Two-stage air conditioners operate at two different speeds. On hot days, they run at full capacity (100%) to provide maximum cooling. On milder days or when less cooling is needed, they operate at a lower capacity (about 60-70%). This not only reduces energy costs but also improves dehumidification.
• Variable-speed ACs run at multiple speeds based on your home’s cooling needs. Most variable-speed systems can operate at capacities between 25-100% to precisely match your home’s cooling needs, improving temperature control and energy efficiency.

Installation Complexity

The cost of labor can depend on a few key factors. For starters, the condition of your ductwork plays a big role – if it's in good shape, the job will be much easier.

Another factor to consider is whether you're installing the new system in the same spot as the old one. A simple swap in the same location is easier and cheaper. If you're switching to a different type of cooling system or need electrical or structural modifications, the job becomes more complicated and expensive. Basically, the more complex the job is, the higher the labor costs will be.

Additional Add-ons

HVAC add-ons on a popular choice for many homeowners looking to improve their air quality, comfort, and convenience. A few add-ons to consider include:

• Smart thermostats
• Air purification systems
• UV lights
• Zoning systems
• Whole-house dehumidifiers and humidifiers

Signs You May Need a New Air Conditioner

If you’re unsure about whether it’s time to replace your current AC unit, don’t worry – you’re not alone. However, knowing a few of the tell-tale signs you need a replacement can help you avoid a complete breakdown when you need cooling the most.

• Age. Air conditioners in Houston typically last about 10-15 years before they become more prone to breaking down and lose efficiency. Because of Houston’s hot, humid climate, you may need to consider a replacement after 10-12 years.
• High Energy Bills. It’s not uncommon for your energy bills to spike during a heat wave as cooling needs increase. However, if you’re noticing a huge increase without a change in usage patterns, it may be time to consider AC replacement.
• Reduced Comfort: Older air conditioners may struggle to maintain the same level of comfort they once did. This can result in higher indoor humidity levels and uneven temperatures, leading to hot and cold spots throughout the house.
• Frequent Repairs. While an occasional repair is common, frequent repairs signal it may be time for an upgrade. Not only will you save money on costly repairs, but a new, high-efficient system will lower your monthly energy bills.
