8 Ways to Repair Boilers and HVAC Systems

Boilers and HVAC systems are complex systems that can be tricky to repair. Once an issue is repaired, it’s usually not necessary to regularly repair the system. If you’re a business or homeowner and you are experiencing a malfunction with your boiler or HVAC system, then you should be aware that there are eight ways to repair boilers and HVAC systems, and here is an overview of them all.

Check the Thermometer 

If your thermostat isn’t working, you might think that it will cost hundreds of dollars to fix the problem, but in most cases, a thermostat fix can be as cheap as $10 or even less. If you have an older thermostat, then you need to listen for a telltale “click,” which indicates that it’s been turned on. If you have a digital unit, then one of the first things you need to check is the batteries. A simple battery swap could easily fix your problem. In some situations, the thermostat itself will need to be replaced. Thermostats will cost more than $10, however, and the exact cost will depend on the specific thermostat that you opt for.

Check For Leaks and Dripping

A boiler system that leaks could signify a serious problem, as the excess moisture will eventually lead to corrosion and the unit will eventually require replacement. Fortunately, not all boiler leaks are serious, and some can even be repaired, making replacement unnecessary. In some cases, boiler operators discover that a problem is not a leak at all and that it’s more of an issue with condensation. This is a lot less serious and doesn’t usually cause any damage to the boiler system.

Don’t Forget to Check the Ducts

In many cases, you can find the ductwork either in the basement or the attic of a home or business. Some problems that you might find with ductwork are clogs, dirt and corrosion, cracks, dents, and more. These problems can cause air to fail to flow properly, if it’s able to flow at all. Luckily, it’s easy to repair ductwork, and if you find cracks and tears, then you can easily repair them with duct tape. Clogged ducts can be cleaned out with a vacuum cleaner and doing so should immediately fix a problem in which air has not been flowing properly.

Diagnosing a Problem with No Heat

There could be any number of underlying issues leading to your heat failing to work. The problem could involve the thermometer, a safety switch that needs to be bypassed, you could have a broken pump, or one of many other possible issues could be the cause. Only a licensed HVAC technician can properly fix the problem and get the heat working again. Keep in mind that it’s important for you to refrain from tinkering with the system, as there may be special equipment that is needed to fix the system that you don’t have access to, or you could be placing yourself and others in danger since HVAC systems are combustible. 

Is a Dirty Condenser Your Problem?

If your condenser is clogged with dirt and debris, then it can cause your HVAC system to fail to work properly. A clogged and dirty condenser can be cleaned, which will enable it to work efficiently again. However, it’s imperative that you refrain from getting any electrical components wet, or you could end up with an even worse problem. It can be challenging to properly clean the condenser without getting electrical parts wet, which is why having a professional take care of the problem is highly recommended. 

Is There a Pilot Light Problem?

Older boiler systems and even some of the newer systems require that a pilot light be lit in order for the system to work and properly provide heat to a home or business. Whether your pilot light must be lit manually, or it’s electronic, if it’s not properly lit, then this is something that you should not try to fix on your own. Again, HVAC systems are combustible, and if you’re not properly trained and certified, then you could end up causing an explosion or some other dangerous situation. A licensed HVAC professional can easily light your pilot in order to ensure the system is working as it should.

Is There Power Going to Your Power Panel?

One problem that could cause your boiler or HVAC system to fail to work properly is the power panel system. This is where fuses are that provide power to your entire home or office, including the HVAC system. Your power panel system, or breakers, could need to be reset in order for your HVAC system to work. If you don’t have experience managing fuses and breakers, or you don’t feel comfortable trying to reset yours, then you can contact a professional HVAC professional who can determine if the power panel is in fact the problem, as well as repair whatever issue is determined. 

Is it Your Evaporator Coils?

Your evaporator coils absorb heat in order to provide adequate cooling for your home or office. However, if these coils become clogged and dirty, they’re not able to work properly, meaning that your home or office won’t be cooled off. It’s relatively easy to clean the evaporator coils in order to ensure that they begin working again, but a professional can perform the job more thoroughly and properly.
