  • What are some signs my furnace may be in need of repair?

    Deciding when to replace your furnace in your Valparaiso, Indiana home involves considering several factors. Here are some key indicators that it might be time to replace your furnace:


    Age of the Furnace: The average lifespan of a furnace is typically around 15-20 years. If your furnace is reaching or surpassing this age, and you are experiencing frequent breakdowns or reduced efficiency, it may be more cost-effective to invest in a new, energy-efficient model.


    Frequent Repairs: If you find yourself repeatedly calling for furnace repairs and the costs are adding up, it may be a signal that your furnace is becoming less reliable and more prone to issues. Investing in a new system could save you money in the long run.


    Increased Energy Bills: As furnaces age, they often become less efficient, leading to higher energy bills. If you notice a significant and unexplained increase in your heating costs, it could be a sign that your furnace is no longer operating at peak efficiency.


    Inconsistent Heating: If some rooms in your home are consistently too hot or too cold, or if your furnace struggles to maintain a consistent temperature, it may indicate that your system is no longer capable of distributing heat evenly.


    Strange Noises: Unusual noises, such as banging, rattling, or popping sounds, may indicate mechanical problems within the furnace. If these issues persist despite repairs, it might be time for a replacement.


    Yellow Pilot Light: A pilot light that is consistently yellow instead of blue can be a sign of incomplete combustion, potentially producing carbon monoxide. This is a serious safety concern, and if you observe a yellow pilot light, you should turn off the furnace immediately and seek professional assistance.


    Visible Signs of Rust or Cracks: If you notice visible signs of corrosion, rust, or cracks in your furnace, it could indicate structural issues. A compromised furnace can pose safety risks, and replacement may be necessary.


    Changes in Home Comfort Needs: If you've made significant changes to your home, such as additions or renovations, and your current furnace is no longer able to meet the heating demands, it may be time to upgrade to a more powerful or efficient system.


    Safety Concerns: If your furnace poses a safety risk due to issues such as gas leaks, carbon monoxide leaks, or repeated malfunctions, it's crucial to prioritize the safety of your household and consider replacing the unit.


    When contemplating furnace replacement, it's advisable to consult with a licensed HVAC professional. They can assess the condition of your current system, discuss your heating needs, and provide recommendations for the most suitable replacement options. Investing in a new, energy-efficient furnace not only improves comfort but can also result in long-term energy savings.

  • How often should I change my furnace filter?

    You should replace the air filter in your furnace on a regular basis. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets and the size of your equipment. 


    Please give us a call and we can give you proper guidance.

  • What temperature should I set my thermostat?

    Normal cooling settings are 75 degrees - 80 degrees. Normal heating settings are 68 degrees - 72 degrees. You should always set your thermostat to the highest possible setting that is comfortable for you in the summer, and the lowest comfortable setting in the winter. Setting your thermostat in this way will maximize your energy savings. On average, every 1 degree of temperature change is equal to about 1% energy savings. For example, changing your thermostat setting from 75 degrees to 76 degrees in the summer could result in savings on your cooling costs.

  • Are there tests that can be done to find air leaks that are causing my home to leak hot or cold air?

    Yes, we have invested in equipment that allows us to determine a home's airtightness so we can search for leaks. Finding and addressing such leaks will help you save on your energy bills since you will be able to better control the air circulating in your home.
