Professional AC Installation & Replacement in Denver, CO

Think about the feeling of stepping out of the blazing Denver sun and into a perfectly cool home. Modern air conditioning systems are incredible feats of engineering, creating a quiet, comfortable sanctuary where you can relax and recharge.

At Pasterkamp Heating & Air Conditioning, we see a new AC unit as a major upgrade to your home life. We approach every AC installation with a focus on providing total comfort and security, ensuring your new system delivers safe, reliable, and refreshingly cool air for years to come. Contact us today to schedule a consultation for a new AC unit.

Investing in a New Air Conditioner Is an Investment in Your Life

A new air conditioner provides immediate and noticeable comfort, eliminating hot spots and creating a consistent temperature throughout your home. Beyond that feeling of relief, a modern AC installation brings significant long-term value. Today’s high-efficiency air conditioning systems use far less electricity to produce the same amount of cooling.

This improvement is measured by the Seasonal Energy Efficiency Ratio (SEER). A higher SEER rating on your new system means lower monthly energy bills, allowing the unit to pay for itself over time. Plus, with advanced filtration options, you can also see a reduction in dust and allergens, creating a healthier living space.

What You Can Expect During Your Air Conditioning Replacement

We believe the installation process should be as comfortable as the cool air your new system will provide. We look at your current setup, including the existing duct system, to determine the exact needs of your space. We calculate the correct size for your new unit, as a system that’s too large or too small will struggle to cool effectively and efficiently.

On the day of the installation, our technicians work cleanly and respectfully in your home. We safely remove your old unit, properly recovering any old refrigerant. We then install the new equipment, which can include the outdoor condenser and the indoor air handler. All connections for refrigerant, drainage, and electricity are made with precision. Before we leave, we test the entire system, checking airflow, temperature output, and drain lines to make sure every component is working in perfect harmony.

We Install a Variety of Modern, High-Efficiency Air Conditioning Systems for You and Your Denver, CO Family

Your home is unique, and your cooling system should be too. We work with top-tier equipment and can help you find the right fit from a range of excellent air conditioning systems.

  • Central Air Conditioners: These are the most common type of system. A split system uses an outdoor unit (condenser) paired with an indoor unit (an air handler) to distribute cool air through your home’s duct network. They are powerful, efficient, and great for cooling an entire house.
  • Ductless Mini-Splits: If your home doesn’t have existing ductwork or if you want to cool a specific area like an addition or a stubborn hot room, a ductless system is an excellent option. It consists of a small outdoor unit connected to one or more indoor heads, giving you room-by-room temperature control.
  • Heat Pumps: A heat pump is a fantastic all-in-one solution. It functions just like an air conditioner in the summer, moving heat out of your home. In the cooler months, it reverses the process to efficiently bring heat into your home. This makes it a great choice for year-round comfort in the Denver area.

We can walk you through the benefits of each system to help you make an informed decision for your home.

Common Signs That Your Current Air Conditioning System Needs Replacement

Air conditioners don’t last forever. If your system is over 10-12 years old, it’s a good time to start thinking about a replacement, even if it’s still running. Older units are far less efficient and more prone to breaking down. You may notice your electricity bills climbing higher each summer as the unit works harder to maintain the set temperature. Frequent repair calls are another significant sign — investing that money in an air conditioning replacement is often a wiser choice.

Also, listen for unusual noises or look for signs of a water leak near the indoor unit, which could point to a failing component or a clogged drain line. A refrigerant leak is another serious issue that often makes replacement the best option.

Here Are a Few Additional Points to Keep in Mind About Your New AC System

Getting the most from your investment involves a few more details. Paying attention to these elements helps you achieve optimal comfort and efficiency for years.

  • The Power of SEER: The Seasonal Energy Efficiency Ratio is a direct measure of how much cooling your system produces for each unit of electricity it consumes. Upgrading from an old 10 SEER unit to a new unit that’s rated 16 SEER or higher can dramatically reduce your cooling costs.
  • Your Ductwork’s Role: Your AC system is only as good as the duct network that delivers the air. If your ducts are old, poorly sealed, or improperly sized, you can lose a significant amount of cool air before it ever reaches your rooms. We can assess your ductwork to see if improvements are needed.
  • Correct Sizing Matters: We mentioned this before, but it’s worth repeating. An oversized unit will cool the house too quickly and shut off, leading to poor humidity control and wasted energy. An undersized unit will run constantly without ever reaching the desired temperature. We perform calculations to find the perfect size for your home.

Pasterkamp Heating & Air Conditioning Offers Comprehensive Services to Keep Your System in Top Shape

Our relationship doesn’t end after your AC installation. To protect your new investment, we offer complete AC maintenance services. An annual tune-up keeps your system running at peak efficiency, helps prevent unexpected breakdowns during a heat wave, and can extend the life of your equipment.

During a maintenance visit, we clean critical components, check refrigerant levels, and inspect the electrical and mechanical parts. And if something does go wrong, our skilled technicians are ready to diagnose the problem and provide fast, effective AC repairs to get your cool air flowing again.

Ductless Heat Pumps are now a realistic option for any home or office, in any climate. Residential and commercial systems offer year-round, high efficiency heating and cooling for a variety of rooms.

“I would choose them again and again.”

Pasterkamp has installed heating and air conditioning systems in two of our Colorado homes. In both cases, the systems have worked flawlessly. This company is a Colorado institution. I would choose them again and again.

“James really worked hard to find a solution and I really appreciate his efforts.”

Both Teresa when I called to set up service, and James who came out to check our unit were very polite and friendly. James really worked hard to find a solution and I really appreciate his efforts. We finally got our AC working. I would very much recommend these guys. Thanks much.

“I was happy to speak to someone who really knows the products and tells you what you need and didn’t try to upsell me.”

Brandon was very easy to speak to, he told me exactly what will happen and when. I have already given my sister Pasterkamp's number! I was happy to speak to someone who really knows the products and tells you what you need and didn't try to upsell me. I will always use Pasterkamp from now on!! I am getting a furnace that's the right size for my house and a heat pump installed
