If you're considering a new AC, sizing the system correctly is one of the biggest challenges of the job.
We make sure we get it right by performing a load calculation during your free estimate.
What does a perfectly-sized AC get you? Lower energy bills, a longer-lasting system, and better cooling coverage across the home.
AC size does affect system cost, but since AC size and home size are related, you wouldn't want to save money by choosing a system smaller than your home's needs!
Every air conditioner is rated on its efficiency by what's known as a SEER score. Systems with higher SEER ratings cool your home more efficiently. They also cost more to buy.
The trick is to find a system that's both efficient and within your budget. We can help with that.
Even the most efficient AC system won't last long without reliable ductwork.
That's why we always say that additions and repairs to ductworkâif necessaryâare well worth the investment at the time of the installation.
Proper Air conditioning sizing depends on your homeâs square footage, insulation, elevation, and sun exposure.
In Denver, higher elevation and lower humidity can impact cooling performance, so a Manual J load calculation is critical to avoid oversizing or undersizing your system.
If your AC is over 10â15 years old, needs frequent repairs, or struggles to cool evenly, replacement is often more cost-effective. New systems are significantly more energy-efficient and better suited for Denverâs fluctuating temperatures.
Most standard AC installations can be completed in one day, though more complex installs, such as ductwork modifications or system upgrades, may take longer. Proper AC sizing depends on your homeâs square footage, insulation, elevation, and sun exposure.Â
A higher SEER rating improves energy efficiency, but in Denvers moderate cooling climate, many homeowners find a mid-to-high efficiency system offers the best balance between upfront cost and long-term savings.
Yes, newer systems use less energy to produce the same cooling output. Homeowners often see noticeable reductions in energy bills, especially if replacing an outdated unit.

Ductless versus ducted is among the most fundamental differences in AC design. Often referred to as central air, a ducted system moves cooled air through ducts where it eventually enters rooms through registers. Often referred to as a mini-split, a ductless system sends cooled air directly to one or more blowers that are installed strategically throughout your home.
Selecting the appropriate air conditioner size for your home is essential for effective cooling. Each home is unique and several key factors determine the appropriate cooling power needed. In this article, we will explore the following topics to ensure you select the right AC unit size for your home.
Youâll have to take a lot of factors into account before deciding to get a new air conditioner. For example, you should consider the advances in modern technology. If you get a replacement, you wonât just be paying for a new version of your old AC unit. Here are some of the ways that modern ACs outclass old models.
