Our Promise To You Is To Perform The Correct Furnace Repair Service At An Honest Price 

The first step in any heating repair service is to turn your system on to see how it is working. If you perform annual furnace tune-ups, your system should be winter ready. However, there are many aspects that could cause a furnace to not operate at its peak performance. If it is not heating the home, there are strange odors or noises, or the system seems to cost you more in utility bills, it is time for an expert diagnosis. 

What Our Heating Repair Service Includes 

The first step in any furnace repair service is the proper diagnosis. Many factors can contribute to a malfunctioning or inefficient heating system. Sometimes, wires are chewed through by rodents, or dirty filters can cause the system to work harder than it should, and a dirty or poorly maintained system could quit working when you need it most. Our team will perform a thorough evaluation, checking the system from top to bottom to determine the cause of the problem and provide multiple repair options.

If you've noticed any of these problems, don't hesitate to contact us online or call (760) 276-6690 to schedule a reliable furnace repair service in the Carlsbad area today!

Common Furnace Problems

Some of the most common reasons a furnace needs repair is age and lack of maintenance. In order to keep your heating system in top condition, it is important to schedule annual tune-up services. During each tune-up, our highly trained specialists will perform a thorough evaluation of the system, clean the burners and check all system and safety functions, as well as change the filter. Dirty filters are especially damaging and can lead to inoperable systems, costly repairs, or the need for replacement.

Dirty Filters

We will replace or clean the filters during our annual tune-up service, but also recommend that homeowners replace them every three months, especially if using the air conditioning system in the summer, if there are pets in the home or the home is located in an area with high dust such as near major roadways. 

Normal Wear And Tear

A home’s furnace will age over time and develop problems through normal wear and tear of the system. The best way to prevent problems and extend the life of the furnace is through regular tune-up services each year. 

Pilot Control Problems

Ignitor systems can become worn over time and stop working. In a well maintained and newer system, this can typically be repaired or replaced. If the system is older, out of warranty, or has been poorly maintained, it may be time to upgrade to a new high efficiency furnace. 

No Heat/Not Enough Heat Being Produced

When a furnace does not produce proper heat, or no airflow is coming in at all, it could be due to several factors. Leaking ducts and clogged filters are the most common reason a heater will not produce efficient heating throughout the home.

Continuously Runs/Won’t Turn Off

When a home’s furnace runs, it will cycle on and off during normal functioning. However, if it won’t turn on at all, or continually runs without cycling, that indicates it may need a heating repair service. The problem may be in the settings, a faulty limit switch, or it could be a wiring problem. Many times, homeowners will go to use their furnace only to find that the wires have been damaged or even chewed through by small rodents. 

Makes Unusual Sounds

Some noises when the furnace runs are normal, such as banging or popping sounds. This could just be the heat expanding and contracting inside of the ducting. However, some noises are a sure sign that the furnace is in need of repair. Scraping, screeching, and constant or excessive banging noises are all signs there is a problem somewhere in the heating system. 

Strange Smells

Newly installed furnaces typically emit a strong odor when they first run, and will usually dissipate within the first cycle. However, if homeowners are experiencing electrical smells, mold or mildew, burning, or gas smells, the furnace should be turned off and a call to our expert heating repair service professionals should be made.

Prevent Furnace Problems With Regular Maintenance

Regular maintenance is crucial for ensuring the efficient and reliable operation of your furnace, especially during the colder months when you rely on it for warmth. By scheduling routine maintenance, you can avoid costly repairs and extend the lifespan of your heating system. 

Key benefits of regular furnace maintenance:

  • Increased energy efficiency: Regular maintenance ensures that your furnace operates at its peak efficiency, reducing energy consumption and lowering utility bills.
  • Improved indoor air quality: Cleaning or replacing air filters during maintenance helps remove dust, allergens, and other contaminants from the air, promoting better indoor air quality and respiratory health.
  • Prevention of breakdowns: Maintenance allows HVAC technicians to identify and address minor issues before they escalate into major problems, reducing the likelihood of unexpected breakdowns and the need for emergency repairs.
  • Extended lifespan of the furnace: Proper maintenance helps keep all components of the furnace in good working condition, minimizing wear and tear and prolonging the lifespan of the system.
  • Optimal comfort: A well-maintained furnace distributes heat evenly throughout your home, ensuring consistent comfort in every room without hot or cold spots.
  • Safety: Regular inspections during maintenance can detect potential safety hazards, such as gas leaks or carbon monoxide leaks, allowing for timely repairs to prevent accidents or health risks.

Scheduling regular maintenance for your furnace offers numerous benefits, including improved energy efficiency, indoor air quality, and comfort, as well as preventing breakdowns and ensuring safety. Investing in preventive maintenance not only saves you money in the long run but also provides peace of mind knowing that your heating system is functioning optimally when you need it most.

What To Expect With A Heating Repair 

Our heating repair specialists will also perform a full safety inspection. They will then perform temperature checks that will tell them if the system is heating efficiently before and after the heat exchanger.

Blocked airflow is also one of the most common causes of an inefficient or non-working heating system. During our seasonal tune-up services, we will always clean or replace the filter and recommend homeowners regularly check their filters throughout the year. A clogged filter can harm your furnace and air conditioning system.

During our heating repair, we will also check all electrical components, the operating pressure, fan motor and venting to ensure there are no leaks, cracks or other problems that could be a safety concern.

Once we have diagnosed the heating issue, we will provide homeowners with multiple options and recommendations for a permanent and affordable heating repair. If the heating system is more than 10 – 12 years old, we may recommend replacing the system to improve efficiency, lower utility costs, and ensure you have the best heating system when you need it most.

  • Why Isn't My Home Getting Warm Enough?
    There are a few reasons why your furnace may not be warming your home efficiently or evenly. One of the most common reasons is a leak in the ducting. If there is a small hole or the ducting is improperly installed, it could leak out warm air and cause the air pressure to drop and the system then provides inadequate heating. Additionally, dirty filters will also cause a restriction in airflow making the system work harder. This can lead to a broken system, which is why regularly changing and/or cleaning your air filters is so important.
