Why Heating Maintenance Matters

A well-maintained heating system lasts longer, runs more efficiently, and saves you money on your energy bills. Plus, routine heating system maintenance can reduce unexpected breakdowns and improve comfort throughout your home.

For homeowners in the Denver and Boulder areas, Applewood recommends an annual heating system tune-up—especially before winter hits. Regular maintenance helps detect small issues before they become costly repairs, ensures safe operation, and can even extend the lifespan of your boiler or furnace by several years.

Our experienced technicians perform complete system checks, from burners to thermostats, to make sure every component is working properly.

Professional Boiler Maintenance 

Applewood’s boiler maintenance service is designed to keep your heating system operating safely and efficiently through Colorado’s coldest months. During your annual maintenance visit, our experts:

  • Inspect and clean the burner, combustion chamber, and heat exchanger
  • Check boiler pressure, flue pipes, and air dampers
  • Examine the pilot light and thermostat calibration
  • Bleed radiators to ensure even heat distribution
  • Look for leaks or signs of corrosion throughout your system

Our team follows a proven process to identify inefficiencies, safety risks, or performance issues—helping you avoid mid-winter breakdowns and emergency calls.

Call Applewood at (720) 780-9143 to book your annual boiler tune-up and keep your home cozy all season long.

Furnace Maintenance and Cleaning

If your home uses a furnace instead of a boiler, Applewood has you covered. Our furnace maintenance service helps ensure strong airflow, consistent heat, and safe operation. We check ignition systems, heat exchangers, filters, and ventilation to ensure optimal performance and energy efficiency.

Our experts can spot early warning signs—such as short cycling, strange noises, or reduced heating output—before they lead to a breakdown. With regular maintenance, your furnace will last longer and use less energy throughout the winter.

Comprehensive Heating System Maintenance

Applewood provides full-service heating maintenance for all types of systems, including furnaces, boilers, radiant heating, and hybrid units. Whether you own a gas or electric system, our licensed HVAC professionals can fine-tune it for maximum efficiency.

A thorough heating system tune-up includes cleaning filters, inspecting ductwork, tightening electrical connections, lubricating moving parts, and verifying system airflow. We also test safety controls to ensure your equipment runs reliably and safely.

Even if your system seems to be working fine, preventive maintenance can cut your utility bills by 10–15% and reduce costly emergency repairs later.

Frequently Asked Maintenance Questions

How often should I schedule boiler maintenance?

Unless you’re experiencing regular issues with your boiler, an annual tune up in the fall should be sufficient.

What’s the difference between a boiler and a furnace?

A boiler integrates with your plumbing system. It uses hot water, distributed through radiators or beneath your floors, to warm each room in your home. A furnace uses a blower to deliver hot air through a duct system to vents that are placed throughout your home.

Why is my boiler making banging and whistling noises?

Loud banging or whistling sounds often indicate boiler blockage. Corrosion or limescale buildup can restrict water flow and create additional pressure inside of your boiler. It could also mean trapped air in your pipes that needs to be bled out. Don’t ignore these signs, schedule a boiler system repair check with Applewood.

How long do boilers typically last?

Standard hot water boilers will last around 20 years. The lifespan of your boiler is affected by water quality, length of use and the amount of maintenance it receives.

What should I do if my boiler stops working in the middle of winter?

Call Applewood immediately. We’ll make your call a priority. Our experienced technicians will determine if your current boiler needs to be repaired or replaced. If you need a new boiler, we can expedite the process so that your home has heat again within a day.

Does Applewood offer emergency services?

Our technicians work from 6:00am-10:00pm every day. We don’t charge “emergency” fees when you call in the early morning or evening.
