Yes, regular boiler service is an important task that allows you to extend the lifespan of your boiler and catch any possible malfunctions that can lead to further damage later down the road. Your boiler system is an important feature that allows you to maintain a comfortable living environment for you and your family. Therefore, by keeping up with maintenance, you can rest assured knowing it is functioning optimally while saving you money on your monthly energy bill. 

Generally speaking, homeowners should aim to have their boiler serviced at least once a year. We recommend doing so in the early Fall before temperatures begin to drop. By having your boiler serviced in early September or October, you can ensure your HVAC unit is ready to operate as efficiently as possible as the temperature outdoors begins to drop. In addition, it will also provide you with ample time to fix any potential problems that may be discovered during your boiler inspection. That way, you can rest assured knowing that the problem has to be dealt with well in advance. 

Standard boiler maintenance includes: 

  • Inspecting each mechanical component 
  • Cleaning your boiler 
  • Ensuring the heat exchanger is working properly 
  • Inspection of the condensation system
  • Review of your thermostat and safety controls 
  • Make sure that all boiler features are working optimally 

Are you overdue on your boiler maintenance? If the answer is yes, then it’s time to book an appointment with the certified and professional HVAC team at M&K Heating and Air Conditioning today!

Knowing when your boiler may need servicing is key to catching potential damages early and preventing further damage from occurring that could have otherwise been preventable. Here are some of the signs that you should look out for around your home that may indicate you require professional assistance: 

  • Leaking water from your pipes or the boiler itself 
  • You have no hot water 
  • There are unusual noises coming from your boiler 
  • There is gas or steam leaking from your pipes or your boiler system 
  • Your boiler will not turn on 
  • You are experiencing electrical malfunctions 
  • You are unable to heat your home or water properly
