When to consider heating and furnace services

When should you consider heating installation and furnace replacement services? Heating systems last anywhere from 15-30 years if properly maintained. Simply put, you should replace your heating system when it no longer provides heat. Below you will find some additional considerations for installing a new furnace:

Seasonal Maintenance

A heater needs to be serviced annually to ensure that it’s running efficiently. Seasonal maintenance is a good time to inspect your unit and compare it to the new models on the market. If your heater is older than 15 years, replace it.

Improve Air Quality

Your heating unit is connected to the air system in your home. This system must be kept clean to ensure good air quality for the rest of your home. If your heater is experiencing issues, consider replacing it for better air quality.

Gas Leak

Damage to the heat exchanger can lead to a buildup of carbon monoxide, which is dangerous to everyone in your home. If you smell rotten eggs or your burner turns yellow, orange, or red, evacuate and call a professional immediately.

Energy Efficiency

The older the heater, the worse the energy efficiency will be. For that reason, it is important to consider updating the model of your heater every 10 years or so to ensure that your heater does not end up driving up your utility bill.


Heaters are connected to either electricity or gas, so they pose a potential danger as they start to grow old and break down. Additionally, your heater is connected to your home’s airflow, so it can spread toxins if left ignored. It is essential to consistently inspect your heater to ensure its integrity.

Excess Dust

Dust can be a clear sign that your furnace is failing at removing airborne particles. If filter replacement or cleaning isn’t working, there may be permanent damage to the internal mechanics of your heater. A replacement is highly recommended.

Heating maintenance ensures the health and longevity of the heating systems in your home. Also, your heating affects the air quality in your home, so it’s important to keep it clean to ensure that no contaminants are dispersed. Lastly, periodic maintenance will give you a rough idea of your heater’s age and inform you about replacing it.

It is highly advised that you leave it to the professionals, especially if you are inexperienced, as many dangerous components are involved. 

Your HVAC systems should be serviced twice a year, once in spring and fall, ideally before summer and winter.

This answer will depend on the size of house you own, your insulation, wall setup and available space. However, we at Max’s Fix-it 24/7 can help determine what size is appropriate for your home. With extensive experience, we are more than happy to help you select a suitable size for your home.
