The importance of professional furnace repair

Furnaces are complex devices and often involve electrical or gas connections. They can prove dangerous to inexperienced, and a furnace is connected to other aspects of your home, such as your airflow system and your water heater so that a mistake could damage other systems. We want to make home repair as hassle-free as possible so our technicians can inspect your furnace and ensure it runs efficiently.

Seasonal Maintenance

With any heating system, central or otherwise, you want to perform a yearly maintenance check to ensure everything is running efficiently and there is nothing faulty with the heater. Older systems will require more than just an annual check-up-roughly around six months or so. The more frequent the maintenance your heating system needs, the better it may be to replace. 

Improve Air Quality

Your heating system is connected to the airflow system of your home. If you notice the air quality is greatly diminished, you may want to consider replacing your heating system and checking up on the airflow system. Replacing your heating system can significantly improve your air quality as a result.

Energy Efficiency

Older heating systems will require significantly more energy to reach the same heat levels of more modern and efficient heating systems. Although it seems trivial, this effect can dramatically compound itself, ensuring that you have a hefty energy bill as a result. If your heat system has issues heating your home, consider replacing it with a more energy-efficient option. 


Heating systems are not elements to be taken lightly in your home. If you have a faulty or old heating system in your home, the result could be poor air quality and potential fire risk. Therefore, always maintain and check on your heating system, and if it is getting old, replace it for safety concerns.

Ronald installed our furnace this past summer in a timely and professional manner. He took the time to explain exactly what the process would look like and once it was installed he thoroughly explained how to maintain the furnace properly (how often to change the filter, the process for changing the filter and how to set reminders on our new thermostat). I was so impressed with Ronald’s knowledge and prompt completion of the furnace installation - despite it being old and underneath the house. Recently, our furnace was not blowing hot air and I was so happy that Ronald was the technician assigned to help us. He not only fixed the issue but walked me through how to prevent further issues from happening. When your home needs repairs it can feel like a hassle - with Ronald’s professionalism and kindness it doesn’t feel that way at all. I would highly recommend him to work on any job!

This answer will depend largely on the size of the filter in question. The consensus is that you should switch out your filter once every 90 days or 3 months. For larger-sized filters, roughly 3-4 inches or 5-6 inches, you want to swap them out every 6-9 months, respectively.

Common furnace repairs include a malfunctioning thermostat, dirty filter, no heat exchange from the heater, rattling noises, limit switch replacement, frequent over-cycling, or cracked heat exchange.

Yes, a furnace has a filter designed to trap airborne contaminants and keep them out of your heating and cooling system.
