What are the most common issues with a furnace?

The most common issues we see with a furnace are the ones that should be checked on every year right before the cold months when you'd use your furnace. If you get it checked out once a year, you can prevent costly repairs or even replacements in the future, and while there is a typical lifespan on a furnace, you can make it last its longest by making sure it's all taken care of by a licensed and insured professional HVAC technician.

Dirty filters

One of the most common issues with a furnace is a dirty filter filled with dust. If the filter gets clogged, it can make the furnace work a lot harder than it should warm the home, and that will cost more in your electricity bills and make your furnace break down and work less efficiently, making it stop working much faster than usual.

Flickering pilot light

If your pilot light is flickering or won't turn on, it could mean there's too much carbon monoxide going into your house, which can be a dangerous or even fatal situation. Make sure to call your local technician immediately if you're noticing your pilot light isn't working correctly.

Cracked heat exchanger

Your heat exchanger is a device that keeps your furnace running safely. It separates the flames from your air, so if you're smelling any kind of burning smell, definitely call a technician right away. A cracked heat exchanger can turn into a fatal situation if it isn't addressed as soon as possible. Unfortunately, the only solution is to replace the heat exchanger, but it will happen at one point when you have a furnace, and it has to be replaced to keep it running safely.

When should you replace your furnace?

A furnace can last anywhere from 15-30 years. It all depends on how well the furnace is taken care of. There are a few signs to look out for to know if your furnace is reaching the end of its lifespan.

The make and model

Some models run better than other ones do. Do your research to find the best one for your home and where you live, or ask a local furnace technician for their advice.


Since some models run better than others, some are made to last a lot longer. So it depends on the brand and how old it is. Again, ask a local furnace technician to come to check out your furnace if you're worried about the age.

Professional installation

Did a professional install your furnace? If not, you can face a lot of problems down the road because usually if it isn't done by a professional, it breaks codes and policies and could void the warranty. Make sure to get your furnace installed by a licensed and insured professional.

Preventative maintenance

Make sure to get your furnace checked out once a year. Your local furnace technician can come to your home and make sure the pilot light, heat exchanger, and all the other moving pieces are working correctly and safely. It's better to pay for the small cost of preventative service rather than the large costs when something breaks.

Do I have to replace my furnace? Can I do it myself?

There are factors you have to consider when thinking about replacing your furnace. For example, as your furnace ages, it becomes less efficient at heating your home, which means it works harder each year, and that can make your electricity bills higher. However, is it worth spending the money on a new furnace? Will that upfront cost save you money on your electricity bills? Only you can answer that. Also, as new technology comes out, there might be a better model than your current one that is more efficient and heats your home easier, saving you significantly more money on your energy bills. This could be a reason to replace it, but it all comes down to savings and safety.

We recommend you don't try to replace your furnace on your own. There are codes and policies to follow that a licensed furnace technician knows and is trained to do. This ensures your home is safe, and that's important when dealing with a machine that emits carbon monoxide, which can be deadly if it isn't installed correctly.

Diana M.

This was my first time with 1-800-Plumber Air of Pearland. I called with a minor issue with the dishwasher drain hose and asked that a tech be dispatched on Saturday so that I could be home from work. Chad was scheduled between 8am & 10am today (Sat) and arrived just before 9am. Chad was very knowledgeable and explained to me the entire process. He also answered my many many questions about what he was doing as he was doing it. I'm a smart guy but know very little about plumbing. I felt very comfortable with Chad doing the repair. The long and the short of it, 1-800-Plumber Air of Pearland has a new longtime customer and I will request that Chad be sent if possible the next time I have a plumbing issue.

George T.

Fine young man and as far as I am concerned he can be his permanent tech. He was very polite and he was very pleased with him and will be calling us again to work with Manolo. Manolo needs a pat on the back and he did a good job.

Is your old furnace on its last legs?

Furnaces can last between 10 and 15 years, with some exceeding even 20 years. Despite the longevity of your furnace, aging furnaces present more than just a heating problem.

Old furnaces are one of the leading causes of indoor air pollution, increasing the presence of dust, pollen, pet hair and dander, mites, and more allergens in your home. Indoor air pollution also heightens the risk of wheezing, coughing, allergies, and serious respiratory problems.

Worse yet, an old furnace can leak dangerous carbon monoxide into your home, causing everything from nausea to severe illnesses.

Professional furnace installation is essential for keeping your home safe, healthy, and cozy, but not just any installation service will do. Incorrect installation can exacerbate indoor air pollution, create safety hazards, and burn through your budget.

Here are several things to consider before choosing an installation service:
