Why Isn’t Your Air Conditioner Working?

There are many reasons why your air conditioner might not be working as expected, and understanding these common issues can help you identify and address the problem more effectively.

Common causes of AC trouble include: 

  • Dirty or clogged air filters. Over time, air filters can become clogged with dirt, dust, and debris, restricting airflow and making it harder for your AC to cool your home efficiently. Replacing your filters regularly can prevent this issue. 
  • Refrigerant leaks. If your system is low on refrigerant, it may struggle to cool properly. Leaks can reduce efficiency and pose safety risks, so they should be addressed by a professional as quickly as possible. 
  • Frozen evaporator coils. These coils rely on proper airflow to function correctly. If airflow is blocked or refrigerant levels are low, the coils can freeze and stop the AC from cooling your home. 
  • A malfunctioning thermostat. Sometimes, the issue isn’t with the AC itself but with the thermostat. If it’s calibrated incorrectly or has dead batteries, it can prevent the system from operating as intended. 
  • Electrical or wiring issues. Faulty wiring, blown fuses, or tripped breakers can disrupt the power supply to your air conditioner, causing it to shut down unexpectedly or fail to start altogether. 

Knowing the common culprits can help you take the first steps toward restoring your air conditioner’s functionality. If you’re unsure about the cause or need professional help, our knowledgeable technicians are always here to provide expert repairs and advice.

Should You Repair or Replace Your Broken Air Conditioner?

Deciding whether to repair or replace your broken air conditioner often depends on a few key factors, including its age, the extent of the damage, and the cost of repairs. If your air conditioner is relatively new and the issue is minor, such as a worn-out part or a clogged filter, a repair is often the best option. Repairs are typically more cost-effective and can quickly get your system back up and running. A professional inspection can help assess the problem and ensure an accurate, reliable fix.

On the other hand, replacement may be the smarter choice if your air conditioner is over 10-15 years old or if the cost of repairs is approaching or surpassing the price of a new unit. Older systems are often less energy-efficient, meaning a new unit could save you money on your energy bills over time. Plus, newer models come equipped with advanced features that can improve comfort and convenience in your home. Our team can guide you through the process, helping you make the best decision for your needs and budget.

    "I highly recommend this company!"

    I had a new heat pump installation by Marx Mechanical. Thank you Jason, TJ & Tyler. Very professional company to work with. I couldn't be happier with the installation; it exceeds my expectations.

    Susan C.
    "So pleased to have chosen Marx Mechanical!"

    From the initial phone call, to the visit to the showroom, to the install, to the subsequent follow up of such, all the staff (including owner) could not have been more accommodating and more knowledgeable.

    Karen H.
    "Their staff and technicians were exemplary."

    Marx Mechanical responded quickly when our furnace broke down on a cold day in December. They quoted a good price and installed the new equipment promptly. We were impressed with their professionalism and their promptness in dealing with the issue.

    Robert A.
    "Super work!"

    Marx Mechanical Heating and Cooling did a wonderful job in repairing our ductless heat pump system.  I highly recommend the company.

    Leland D.
    "Bravo!"

    The Marx Team came to our rescue when our furnace was on the fritz and installed a new one with exceptional installation standards and had us up and running in no time! They are without a doubt the "Go To" HVAC company in the Durham-York Region!

    Brian B.
    "I would highly recommend Marx Mechanical!"

    Marx Mechanical replaced our old furnace with a new heat pump which has kept our house warm all winter. They worked with us to find the perfect system for our home and our unique needs.

    Serena E.
    "Excellent HVAC company to work with!"

    They took time to work with us to get the best furnace/heat pump to replace our 20-year-old furnace. They've checked in with us regularly, and while we haven't had any issues, we know that they would go above and beyond to fix anything!

    Val R.
    "Marx Mechanical staff are courteous and professional!"

    My furnace suddenly died and Marx Mechanical staff rearranged their schedule to be here the next day to replace my furnace (in a snowstorm). All my questions were answered and they even helped me set up the Daikin app on my phone.

When AC Issues Become HVAC Emergencies

Certain issues with your air conditioning system should not be ignored, as they could qualify as an HVAC emergency. Acting quickly can help prevent further damage to your system and maintain comfort in your home, especially during extreme weather. 

Call Marx Mechanical Heating and Cooling and request emergency assistance if you’re dealing with: 

  • Complete system failure. If your air conditioner has stopped working entirely and won’t turn on, especially during very hot or cold weather, it’s important to seek immediate assistance. 
  • Unusual or loud noises. Grinding, banging, or screeching sounds often indicate serious mechanical issues that need to be addressed right away to avoid further damage. 
  • Unpleasant odors. Foul smells coming from your vents could mean mould, burning components, or other hazardous conditions within the system. 
  • Leaking or excessive moisture. Water pooling around your AC unit or signs of refrigerant leaks could damage your home and pose health risks. 
  • Warm air blowing out. If your air conditioning is blowing warm air despite being set to cool, this could indicate a serious issue with your compressor or refrigerant levels. 

If you notice any of these signs, don’t wait to get help. Our professional team at Marx Mechanical Heating and Cooling is available to provide expert emergency HVAC services and restore comfort to your home.

Request same-day or emergency air conditioning repairs in Uxbridge, Pickering, Newmarket, Oshawa, Ajax, or any of the surrounding Ontario neighbourhoods by calling Marx Mechanical Heating and Cooling at (289) 301-0414!
