10 Common Boiler Problems

A boiler can be a complicated piece of equipment, especially if you do not service it regularly. That is why we are here to help! Below, you will find 10 common problems that boilers may have and their solutions so that you can avoid the problem altogether or fix it quickly.

1. Boiler is Leaking

If you notice water leaking from your boiler, it is important to address the issue quickly. This can be a sign that there is a problem with the seals on the boiler or that there is a crack in the boiler itself. If left unaddressed, this could lead to extensive damage to your home and even a fire.

Solution: Contact professional boiler maintenance in Toronto immediately to have them take a look at the boiler and determine the cause of the leak.

2. Boiler is Making Strange Noises

If your boiler starts making strange noises, it could be a sign that something is wrong. This could be anything from a loose pipe to a problem with the burner.

Solution: Turn off your boiler and call a professional. They will be able to come out and take a look at the boiler to determine the cause of the noise.

3. Boiler is Not Heating Up Enough

If your boiler is not heating up enough, it could be due to several factors, such as a dirty air filter or low water pressure.

Solution: Check the air filter on your boiler and make sure it is clean. If the water pressure is low, you can try increasing it by turning up the pressure valve on your boiler. If this does not work, you should call reliable HVAC services in Toronto to avoid escalating the problem.

4. Boiler Malfunction Light Is On

If your boiler malfunctions light comes on, it could be due to all kinds of things, including low water pressure or a dirty air filter. It also could be that something is wrong with the burner.

Solution: Turn off your boiler and clean or replace the air filter if it's dirty. Check for any loose wires or mounting screws around the boiler system itself.

5. You Smell Gas

If you smell gas, this could mean that there is a leak in the system or that there is not enough air being let into the boiler.

Solution: Turn off your boiler and call your local plumber to fix any issues with the gas line.

6. You Have Low Water Pressure

If you have low water pressure, you will need to determine what is causing the problem. Is it a pump or a water filter?

Solution: You may have a pump issue if your home is on a well and you notice that the pressure tank on your boiler is turning often, which means it's struggling to keep up with the demand for hot water.

7. Water Leaks Around Base of Boiler

When you notice water leaking around the base of your boiler, it could be due to one of several problems. There might be dirt, gravel, or other debris around the base of the boiler that needs to be shaken off, or there might be a crack in one of the valves.

Solution: Clean any junk that has collected around your boiler and inspect the valves for any cracks. If you find anything cracked, you will need to replace it immediately so call your local plumber to help you out!

8. Boiler Suddenly Comes On While You Are Away

If your boiler suddenly comes on while you are away, this can indicate several different things. It could simply mean that someone turned up the temperature but it also could mean that something is wrong with the system itself.

Solution: Check for any broken windows or doors that may have allowed cold air to seep indoors and turn on your boiler as a result.

9. You Notice an Unusual Amount of Condensation Near Boiler

If you notice an unusual amount of condensation near your boiler, it could be due to low water pressure or a dirty air filter. It also could be due to a problem with the burner.

Solution: Turn off your boiler and clean or replace the air filter if it's dirty. Check for any loose wires or mounting screws around the boiler system itself.

10. You Hear an Alarm Going Off

If you hear an alarm going off, there could be several causes for it. It could be due to a dirty air filter or the buildup of lint around the burner.

Solution: Turn off your boiler and clean or replace the air filter if it's dirty.

FAQ

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • Why should I maintain my Furnace or AC?

    An annual maintenance will extend the lifetime of your heating and cooling unit. The technician will diagnose and repair any problem with the unit before it fails, so you won't need to worry about any problems when the weather gets very hot in the summer or extremely cold in the winter.

  • What are mini-split advantages?

    Just as the name implies, a “mini-split” system is a “split system” however available in smaller capacities, for single room to whole house conditioning. Mini-split systems may range from as small as 9,000 BTUh per hour, comparable to say, a small window AC unit, for individual room use, up to 4 and 5 ton capacities for “Room By Room” (also known as “Zoning”) and whole house conditioning. With near universal design, mini-splits are “heat pumps” which provide both heating and cooling for a home. Here are key advantages when compared to traditional split systems:

    Efficiency- Mini-splits are highly engineered systems which offer attractive operating efficiencies, in many instances, eligible for utility company rebates.
    Heat Pump- Most mini-split systems are heat pumps, providing year-round comfort.
    Solar friendly- Due to very low power requirements, mini-splits are an ideal complement to “Net Zero Energy” homes, or any home using renewable power.
    Carbon footprint- Mini-splits are 100% electric, with zero operating emissions of any type.
    Zoning- Most mini-split manufacturers offer systems capable of room-by-room “zoning”, to account for peak demands of a room based upon construction type, exposure orientation and usage.
    Variable capacity- Mini-splits are typically DC inverter driven. That is, a variable speed compressor which modulates in proportion to instantaneous demand. Most conventional split systems, by comparison, operate with an ON-OFF strategy. (Would you use an ON-OFF switch as the accelerator in your vehicle?)
    Location, Location, Location!- Mini-split outdoor units are compact; they can be located far away from noise-sensitive areas, such as bedrooms and home offices. Mini-split indoor units have the ability to be installed where conventional systems cannot.
    They’re perfect for additions and remodels where access to current HVAC system is difficult to access.
    Modern mini-split systems are remarkably quiet; in fact, many times their operation is unnoticed by the end user.
