Common Furnace Issues

(and what to do first)

No Heat

If your furnace isn’t producing any heat, first check your thermostat settings. Make sure it’s set to “Heat” and the temperature is higher than the current room temperature. Then, turn power off to the furnace for around 10 minutes and turn it back using the switch near your furnace or through the breaker. If these steps don’t resolve the issue, your furnace may need professional repair. Don’t let a broken heater leave you in the cold – call UniColorado for expert furnace repair.

No Air Coming Out Of the Vents

When there’s no air coming out of your vents, start by checking if the furnace is turned on and if the circuit breaker hasn’t tripped. Next, examine the air filter and replace it if it’s clogged, then turn power off and on to the furnace. Modern furnaces can be affected by a variety of variables such as overflow switches, condensate drain sensors and more that will shut the furnace off when issues are present. For reliable furnace repair, contact UniColorado to get your heating system back in working order.

Lukewarm Air

If your furnace is producing lukewarm air instead of the desired heat, check your thermostat settings to ensure it’s set to “Heat” and at the correct temperature. Inspect the air filter and replace it if it’s dirty, as a clogged filter can limit airflow and heat output. If the issue continues, your furnace may have a faulty ignition system, flame sensor, or gas valve. Don’t settle for a malfunctioning furnace – reach out to UniColorado for professional furnace repair.

Unusual Sounds (Banging, Screeching, Grinding)

Unusual sounds coming from your furnace can indicate various issues. If you hear squealing or screeching, it may be a sign of worn-out belts or motor bearings. Grinding noises can suggest problems with the motor’s shaft or housing. Loud banging or popping sounds may indicate catasrophic failure. If you experience any of these unusual sounds, turn off your furnace to prevent further damage. For expert diagnosis and repair of your noisy heater, trust the professionals at UniColorado.

How much does furnace repair cost?

We charge $120 to visit your home & diagnose the issue. You’ll be provided with all options possible. Most of our customers spent around $150 – $840* to repair their furnace in 2023*. The total cost to repair a furnace can vary widely.

Most furnaces require annual or bi-annual service. If the unit is not serviced or filter changes are not regular, units can fail prematurely. As the unit ages (typically past the 10-year mark), part failure rates increase. If you haven’t serviced your furnace lately but considering it, we offer furnace maintenance services for functioning units. The most common issues for furnaces in Colorado are sensor failure, blower or inducer draft motor failure, non-functional control boards & dirty filters.


Why is my furnace not working?

At UniColorado, we understand that a malfunctioning furnace can be a major inconvenience, especially during the chilly Colorado winters. That’s why our team of experts is dedicated to providing prompt and reliable furnace repair services to homeowners and businesses in Denver, Centennial, and Littleton.

Common furnace problems can range from ignition issues caused by faulty igniters or gas supply problems, to blower motor failures due to worn-out bearings, electrical faults, or dirt buildup. Thermostat malfunctions, often resulting from dead batteries, wiring issues, or incorrect settings, can also lead to furnace problems. Additionally, heat exchanger cracks caused by age, improper ventilation, or corrosion can significantly impact the efficiency and safety of your furnace.

While this covers some of the most common issues, it’s important to note that gas furnaces or air handler units can fail for a wide variety of reasons. Older furnaces, typically those over 15-20 years old, may experience additional problems that modern furnaces don’t face.

At UniColorado, we understand the urgency of furnace repairs and carry a wide range of common replacement parts in our service vehicles. This ensures that most systems can be repaired the same or next day, minimizing the disruption to your home. In rare cases where specialized parts are required, we’ll work efficiently to order and install them, keeping you informed throughout the process.

Don’t let furnace problems leave you in the cold this winter! Contact UniColorado at (303) 997-0097 for prompt and reliable furnace repair services in Denver, Centennial, and Littleton. Our experienced technicians are equipped to diagnose and resolve a wide range of furnace issues, ensuring your home or business remains warm and comfortable all season long.

Your Common ❓
Frequently Asked Questions
How much do you charge to check my furnace?

The cost to visit the property is $120.

The $120 is waived if we repair or service your unit, so you only pay for what you need.

When is your earliest availibilty?
Can you repair an old furnace?

It depends, but we will try our best.

We ask that you keep in mind that as the unit ages, more and more parts can start failing randomly.

At a certain furnace age, it makes more sense to replace than repair, similar to an old car.

We charge $120 to check the unit and provide all options.

If you just want a replacement quote for your furnace, it’s a free estimate.

What is the most common problem with furnaces?

Dirty filters are the most common cause of furnace part failure; dirty igniters, flame sensors and failed sensors are the most common causes that require a furnace repair to be solved.

Beyond reguarl issues, blowers, inducers and generally the moving parts in furnaces get loose and fail overtime as well.

What is the most expensive part to fix on a furnace?

Typically the heat exchanger is the most expensive part to repair in a gas furnace which can cost upwards of $2,000 and more; if your heat exchanger has cracked, it’s unsafe to operate and it should be looked at as soon as possible.

Inducer draft motors are behind heat exchangers in how expensive they can be to repair.

Generally, with furnace repair, if the repair costs exceeds a reasonable amount for the age of the furnace, it’s typically recommend that the furnace be replaced.

My furnace keeps turning on and off

If you furnace struggles to stay on, it needs to be checked as soon as possible and a furnace repair may be required. Waiting can lead to more serious damage & wear on the system.

How often should I replace my air filter?

All central HVAC systems assume free airflow and are designed as such.

Your air filter is crucial and needs to be replaced every 30-60 days but it varies house to house.

Simply check your filter reguarly and replace or wash permanent filters if dirty.
