Keeping your home or business warm during Denver’s cold seasons can be a challenge, especially with an outdated or inefficient heating system. Did you know that an old furnace or boiler can lose up to 30% of its efficiency over time, leading to higher energy bills and uneven heating? Upgrading to a modern heating system, such as a high-efficiency furnace, boiler, heat pump, or ductless split system, can solve these issues while reducing energy costs.

Types of Heating Systems
Choosing the right heating system for your property is essential to maintaining comfort and managing energy efficiency. Our experts are familiar with all makes and models. We install and replace the following heating systems:
- Furnaces. A popular choice for many Denver homeowners, furnaces are reliable, powerful, and can heat your entire home efficiently. They use ductwork to deliver warm air, making them ideal for larger properties.
- Boilers. Boilers provide an effective way to heat spaces using water or steam. They distribute heat evenly and are known for their durability and energy efficiency, especially in homes with radiant heating systems.
- Heat pumps. A versatile option, heat pumps provide both heating and cooling. These systems move heat rather than generate it, making them a cost-effective and energy-efficient choice, particularly for milder winters.
- Ductless split systems. Perfect for homes without ductwork or for zoning individual rooms, ductless systems offer customizable comfort. They’re sleek, energy-efficient, and ideal for both residential and light commercial applications.
At Allen Service, our experienced technicians can guide you through the selection process, ensuring the heating system you choose suits your space, lifestyle, and energy goals.

Signs You Need to Replace Your Heater
If your current heating system isn’t performing as it should, it may be time to consider a replacement. Watch for the following signs:
- Rising utility bills from older, inefficient heating units that can spike energy costs
- Frequent breakdowns and increased repairs
- Uneven heating and cold spots
- Unusual noises like bangs, rattles, or whistles which can signal significant wear or internal damage
Additionally, most heating systems are designed to last 10–15 years with proper maintenance. If your unit is older, you may be overdue for an upgrade. Keeping on top of your equipment and addressing warning signs early can save you from costly repairs and the discomfort of a sudden system failure.
