Why Doesn’t My Furnace Heat My Whole House?

Published 1/4/2020

This is a question that, as a furnace company, we hear all too often. We know many reasons why some rooms are colder than others in your home, and it is not always due to just a low performing furnace. In addition to these reasons, you may need a furnace service, repair, or replacement in order to keep your home properly heated during the brutal Chicago winters.

Poor Insulation

If it’s not your furnace, poor insulation may be the direct cause for why some rooms are colder than others. If your home does not have sufficient insulation between the interior and exterior walls, cold air passes through very easily. Plus, special insulation surrounding windows and doors is essential to ensuring that heat doesn’t pass through the cracks.

Zone control

Another reason why it may seem that your furnace doesn’t heat the whole house is due to improper zone control. Depending on the location of your furnace, the size of your home, and your ventilation mapping, your furnace may not be able to perform efficiently. A zone control system would be the best solution in this case, which can be easily installed during a furnace repair to support your current HVAC unit.

Wrong Furnace Size

Homeowners often have a hard pill to swallow when they use inexperienced furnace companies. Mr. Duct recommends different furnace sizes depending on the size of your home and the necessity to cope with the often-freezing winters in Illinois. Other companies may have installed furnaces that cannot adequately heat your entire home because they are too small. When you schedule a furnace service, we can determine what would be the best course of action in this case so that you get a warmer home without breaking the bank.

Furnace Service & Repair

If your furnace doesn’t seem to heat your whole house and some rooms are colder than others, it is most likely due to a lack of maintenance. As one of Chicagoland’s trusted furnace companies, we recommend having your furnace serviced at least once a year. We replace dirty filters to improve ventilation, clean ducts to avoid heat blockages, and check thermostat settings for faulty wiring or heat sensor issues. If we encounter any of these issues during your service, we provide on the spot furnace repair so that your home gets back to optimal heating.

Furnace Replacement

A final reason why you’re not getting proper heat in every room of your house is that it is time for a furnace replacement. Old furnaces do not run effectively and can be a nuisance in chilly households. We install new HVAC systems and furnace replacements for our neighbors in the Chicago suburbs and ensure that they are the right size and zone control for each unique home. A new furnace may be just what your home needs to ensure that each room is properly heated.
