Furnace Maintenance in Denver, CO
A furnace that works hard all winter deserves a check before the first cold snap, not after it quits on a freezing night.

Read on to see what a tune-up covers and when to book one, or call (720) 390-2652 to schedule a visit.

What Furnace Maintenance Includes
A maintenance visit is a planned check of the whole heating system while it still works. The goal is to catch small problems, such as a dirty burner or a worn part, before they turn into a breakdown or a safety risk. Exact steps vary by furnace type and age.
Inspection and Performance Check
We look over the furnace and run it through a heating cycle. We watch how it starts, how the flame looks, how the blower runs and whether the system reaches temperature in a normal time. Odd noises, short cycling or uneven heat get noted, and we tell you what we found in plain words.
Cleaning Burners, Blower and Components
Dust, soot and debris build up inside a furnace and cut its efficiency. We clean accessible components such as the burners and the blower assembly, and we check the heat exchanger for visible damage where it can be reached. For a deeper clean, see our furnace cleaning page.
Air Filter Check and Replacement
A clogged filter restricts airflow, makes the furnace work harder and can lead to overheating. We check it on every visit and replace it when it needs it. Many homes need a new filter every one to three months during heating season, depending on the filter type and the household, so check yours between visits.
Thermostat Check and Calibration
We check that the thermostat calls for heat when it should, shuts the furnace off at the right point and reads the room temperature correctly. An inaccurate thermostat wastes fuel and leaves rooms too warm or too cold.
Safety Checks and Carbon Monoxide Testing
A gas furnace burns fuel and has to vent exhaust safely outside. We check the ignition system, the venting and the safety controls, and we test for carbon monoxide around the furnace. If we find a safety problem, we explain it and tell you whether the furnace should stay off until it is fixed. Carbon monoxide alarms in the home are a separate safeguard, and a tune-up is a good time to check their batteries.
When to Schedule a Furnace Tune-Up in Denver
Book before the heating season, in early fall, so the furnace is checked before you need it every day. At the least, have the furnace checked once a year. Early fall is also a good time because heating contractors get busy once the first hard cold arrives, and an early slot is easier to find.
Also book a visit if you have moved into a home and do not know when the furnace was last serviced, or if the furnace has gone more than a year without a check. For households with infants, older adults or anyone with medical needs, a pre-winter check is especially worth it.
Signs Your Furnace Needs Attention
You do not have to wait for the calendar. Call us if you notice:
- Banging, rattling, squealing or grinding sounds
- A furnace that turns on and off in short cycles
- Rooms that heat unevenly or a house that takes too long to warm up
- A yellow or flickering burner flame instead of a steady blue one
- A smell of gas, which means leave the house and call the gas utility from outside
- A sudden rise in your heating bill with no change in your habits
- A furnace that is more than ten to fifteen years old and has never been serviced
If you smell gas or a carbon monoxide alarm sounds, get everyone outside and call 911 or the gas utility from a safe place. Do not wait for an appointment.
What Affects the Cost of Furnace Maintenance?
We do not quote prices without knowing your system, because a visit varies with the equipment. The main factors:
- The type, size and age of the furnace
- How long it has gone without service
- Whether a filter or small parts are replaced during the visit
- Access to the furnace, for example in a tight closet or attic
- Whether you choose a one-time visit or a yearly plan
- Any repair a tune-up reveals, which is quoted separately before work starts
Call us with the furnace type and we will tell you what to expect. If a tune-up shows the furnace needs work, see our furnace repair page. If the furnace is near the end of its life, see furnace replacement.
Furnace Care for Denver Homes
Denver has long, cold heating seasons, with sudden drops in temperature that put a furnace to the test. Dry air and dust also load up filters. The city sits about a mile above sea level, and at altitude a gas furnace may need to be set up differently than at sea level, which is one more reason to have a qualified technician look at it.
Between visits, you can help your furnace:
- Check the filter monthly during heating season and replace it when it looks gray and clogged
- Keep supply vents and return grilles clear of furniture and rugs
- Keep the area around the furnace free of boxes, paint, cleaners and anything flammable
- Test your carbon monoxide and smoke alarms and replace their batteries
- Note any new sound or smell and call us before the problem grows
Colorado law requires carbon monoxide alarms in certain homes, such as when a home with fuel-burning appliances or an attached garage is sold, or when certain permitted work is done. The alarm must be within fifteen feet of each room used for sleeping. See the state statute in Title 38, Article 45 of the Colorado Revised Statutes for the rules that apply to your home.

Frequently Asked Questions About Furnace Maintenance
Early fall, before the heating season starts. That way any problem is found before you rely on the furnace every day, and you avoid the rush once the first hard cold arrives. At minimum, have it checked once a year.
Once a year is the usual advice for a gas furnace. An older furnace, or one that has gone without a check, may deserve a closer look. Your furnace manufacturer's instructions are the best guide for your model.
A tune-up usually covers a system inspection, cleaning of accessible components, a filter check, thermostat calibration and safety checks, including the ignition, the venting and a carbon monoxide test.
That depends on the furnace and how much cleaning it needs. We can give a time window when you book.
Yes, and you should. A fresh filter every one to three months in heating season helps airflow. A filter change does not replace a tune-up, though, because it does not check the burners, the venting, the heat exchanger or the safety controls.
It is usually worth it for safety and for catching small problems early, because a furnace that is checked is less likely to fail in the coldest weeks. A tune-up is not a promise that nothing will break, and we do not promise a specific savings amount.
It depends on the furnace type, age, condition and access, and on whether you pick a single visit or a plan. We quote after hearing about your system. Treat any online price range as general, not as our pricing.
Loud or new noises, short cycling, uneven heat, a yellow or flickering flame, a higher heating bill or a furnace that has never been serviced. If you smell gas, leave the house and call the gas utility or 911 from outside.
It helps. We check the ignition, venting and safety controls and test for carbon monoxide around the furnace. It does not replace working carbon monoxide alarms, which Colorado law requires in certain homes within fifteen feet of sleeping rooms. See the statute linked on this page.
We explain what we found and give you an estimate before any repair work. See our furnace repair page for repairs, or furnace replacement if the furnace is near the end of its life.
