Common Furnace Problems We Repair

Our expert technicians can diagnose and repair all types of furnace issues, including:

Ignition or Pilot Problems

Issues with the ignition system or pilot light can prevent your furnace from producing heat. This could be due to a faulty igniter, flame sensor, or gas supply problems.

Our Solution:

Our technicians can quickly diagnose and repair ignition issues, replace faulty components, and ensure your furnace lights properly every time.

Airflow Problems

Restricted airflow can cause your furnace to overheat, shut down unexpectedly, or distribute heat unevenly throughout your home.

Our Solution:

We'll clean or replace clogged filters, remove blockages from vents and ductwork, and repair or replace malfunctioning blower components.

Thermostat Malfunctions

An improperly functioning thermostat can cause your furnace to run inefficiently, cycle too frequently, or fail to maintain comfortable temperatures.

Our Solution:

Our team can repair or recalibrate your existing thermostat or recommend an upgrade to a programmable or smart thermostat for improved comfort and efficiency.

Unusual Noises

Banging, rattling, squealing, or grinding noises often indicate mechanical problems that require immediate attention to prevent further damage.

Our Solution:

We'll identify the source of the noise and repair or replace worn bearings, loose components, or damaged parts before they cause a complete breakdown.

Frequent Cycling

A furnace that turns on and off too frequently wastes energy and puts excessive wear on system components.

Our Solution:

Our technicians will diagnose the cause of frequent cycling, which may include thermostat issues, improper airflow, or an oversized furnace, and implement the appropriate solution.

No Heat Production

When your furnace runs but doesn't produce heat, it could be due to fuel supply issues, ignition problems, or a faulty heat exchanger.

Our Solution:

We'll conduct a thorough diagnostic to identify the exact cause and perform the necessary repairs to restore heat to your home quickly.

Professional Repair vs. DIY: Why Choose the Experts

While DIY approaches might seem cost-effective initially, professional furnace repair offers significant advantages for safety, effectiveness, and long-term savings.

Safety First

Furnaces involve gas, electricity, and complex components that can be dangerous if handled incorrectly. Our technicians are trained to work safely with these systems.

Accurate Diagnosis

Our experienced technicians can quickly identify the root cause of problems, avoiding trial-and-error approaches that waste time and money.

Proper Tools & Equipment

We use specialized diagnostic equipment and professional-grade tools that aren't typically available to homeowners.

Quality Replacement Parts

We use manufacturer-approved replacement parts that are designed specifically for your furnace model, ensuring optimal performance and longevity.

Warranty Protection

DIY repairs often void manufacturer warranties, while our professional repairs include warranties on both parts and labor.

Long-Term Solutions

We don't just fix the immediate problem—we identify underlying issues and provide solutions that prevent future breakdowns.

Safety Warning

Furnace repair involves working with gas lines, electrical components, and combustion systems that can be dangerous if improperly handled. DIY repairs can lead to:

  • Gas leaks and carbon monoxide exposure
  • Electrical shocks and fire hazards
  • Voided manufacturer warranties
  • Costly damage to expensive components
  • Incomplete fixes that lead to recurring problems

How long does a typical furnace repair take?

Most common furnace repairs can be completed in 1-2 hours. More complex issues might take 2-4 hours. In rare cases involving major component replacement, repairs could take a full day. We'll provide a time estimate before beginning work.

Do you offer any guarantees on your furnace repairs?

Yes, all our furnace repairs come with a minimum 90-day labor warranty, and many repairs include extended warranties of up to 2 years on labor. Parts are typically covered by manufacturer warranties ranging from 1-10 years depending on the component.

Can you repair all furnace brands and models?

Yes, our technicians are trained and certified to work on all major furnace brands including Carrier, Lennox, Rheem, Goodman, York, Trane, American Standard, Bryant, and many others. We service gas, electric, and oil furnaces of all ages.

How do I know if my furnace needs repair or replacement?

We provide honest assessments based on several factors: the age of your furnace (typically 15-20 year lifespan), the cost of repairs versus replacement, energy efficiency concerns, frequency of breakdowns, and safety issues. If repair costs exceed 50% of replacement cost, replacement is often the better investment.

What maintenance can I do myself to prevent furnace problems?

Regular filter changes (every 1-3 months), keeping return air vents clear of obstruction, ensuring the area around your furnace is clean and free of combustible materials, and scheduling professional maintenance once a year are the best ways to prevent furnace problems.

Do you offer financing for more expensive furnace repairs?

Yes, we offer flexible financing options for repairs over $500 with approved credit. Options include no-interest plans if paid within promotional periods and low monthly payment plans. Our comfort advisor can explain all available financing options.

What should I do if I smell gas near my furnace?

If you smell gas, immediately evacuate your home without turning on/off any lights or electronics. Once outside, call your gas company's emergency line and then contact us for emergency service. Do not return to your home until it has been declared safe.
