Your Comfort is Our Priority

Common HVAC Problems We Solve

When Your Comfort System Fails, We're Here to Help

Northwest Indiana's harsh winters and humid summers put significant strain on your heating and cooling systems. When problems arise, Apex Heating & Cooling responds quickly with expert solutions. Here are some of the most common issues our Porter County customers face:

  • Furnace Won't Start or Keeps Shutting Off

    If your furnace is cycling on and off or failing to ignite, it may be due to a faulty thermostat, ignition system issues, or a clogged air filter. Our skilled technicians will identify the problem and offer honest recommendations, whether it’s a quick fix or a necessary replacement.
  • Air Conditioner Not Cooling Properly

    When your air conditioner runs but fails to cool your home, the issue could stem from low refrigerant levels, a malfunctioning compressor, or blocked condenser coils. We utilize advanced diagnostic tools to quickly identify the problem and keep your home comfortable.
  • Strange Noises From Your HVAC System

    Banging, rattling, squealing, or grinding sounds are never normal. These noises often indicate loose components, worn belts, motor issues, or debris in your system. Ignoring unusual sounds can lead to more expensive repairs down the road. We identify and resolve these issues before they cause system failure.

  • Thermostat Issues

    A malfunctioning thermostat can lead to inconsistent temperatures and discomfort. Our team can troubleshoot and repair or replace your thermostat to ensure your system operates efficiently.
  • Uneven Temperatures Throughout Your Home

    If some rooms are too hot while others remain cold, you may have ductwork issues, insufficient insulation, or an improperly sized system. Our leak detection equipment can identify airflow problems that waste energy and compromise comfort. We also offer HVAC zoning solutions to give you better control over different areas of your home.

  • Poor Air Quality

    If you notice dust, allergens, or unpleasant odors in your home, it may be time to check your HVAC system. We offer solutions to improve your indoor air quality, including filter replacements and duct cleaning.
  • Skyrocketing Energy Bills

    A sudden spike in your heating or cooling costs usually signals declining system efficiency. Aging equipment, dirty filters, refrigerant leaks, or poorly maintained systems all force your HVAC to work harder, consuming more energy. Our maintenance services and energy-efficient upgrades help Porter County homeowners reduce monthly utility expenses.

24/7 Emergency Service with Extensive Parts Inventory

Our emergency service isn't an answering service that takes messages. When your furnace quits at 2 AM on a subzero night or your AC fails during a weekend heatwave, you reach a real person who can dispatch immediate help. We maintain the largest stock of HVAC parts and materials of any independent contractor in Porter County. This allows us to complete most repairs in a single visit while other companies order parts and schedule return trips days later.
