Older buildings in Denver have character—but they also come with challenges, especially when it comes to HVAC upgrades.

Installing heat pumps in these properties can be a great move, but you need to go in with your eyes open.

Let’s start with the benefits.

You’re getting both heating and cooling in one system. That alone is a big upgrade for many older units that rely on boilers and window AC units. Comfort improves immediately, and so does efficiency.

You also get redundancy. With multiple indoor units, a single failure doesn’t take out the entire system. That’s something older centralized systems can’t offer.

Now for the challenges.

Electrical upgrades are often unavoidable. Many older panels just don’t have the capacity to handle modern heat pump systems. That’s one of the first things I check on every project.

Refrigerant line installation is another factor. Running lines through older construction takes planning, and clean execution is key if you want to maintain the building’s appearance.

Then there’s cost. Multiple indoor heads can add up quickly, especially in larger units. This is where proper system design makes a huge difference—you don’t want to overbuild, but you also can’t underdeliver.

Compared to traditional gas boilers or window units, heat pumps are more efficient and far more versatile. But they’re not a plug-and-play solution in older buildings.



The key is balancing performance, cost, and practicality.
