Last year our air conditioner died in the middle of the heat wave. We called a few companies but Dr HVAC was the company that had a real person answer the phone and were available to help us right away. Their prices were reasonable and we had our new air conditioner installed in a timely manner. I highly recommend Dr HVAC for all HVAC needs.

Even high-quality products like Lennox air conditioning systems require service from time to time. The fact is, Lennox AC units are complex and rely on many electrical and mechanical components to function correctly. Because of this, there are a variety of reasons your AC isn’t blowing cold air or has stopped working entirely.

Dr HVAC performs any Lennox air conditioning repair in the Greater Toronto Area no matter how complicated the situation. And, in most cases, we can fix your air conditioning system on the spot! That’s because we stock our trucks with everything our technicians might need to get the job done.

Why Is My Lennox AC Not Working?

It might not be an air conditioner issue at all! Be sure to check the settings and replace thermostat batteries before calling for service.

Is your air conditioner freezing up? When ice forms on the evaporator coil, the liquid refrigerant inside the coil cannot do its job; this puts stress on your air conditioner, and it will fail to work properly.

The condition of an air filter will directly impact the performance of an air conditioner. However, the task of changing a dirty air filter is often overlooked.

Airflow is restricted when the vents become blocked by dirt and debris.

Because it is located in the AC unit outside your home, the condenser coil can easily get dirty. If it isn’t kept clean, it takes more energy to keep your home cool, and your energy bills will rise.

Fans are an integral part of any AC system. When the fan in the blower motor slows down or stops spinning, cool air can’t be delivered throughout your home.

Air conditioners depend on refrigerants to operate. If it’s leaking, the system will work harder to keep the home cool, putting undue stress on the system.

Improperly sized air conditioners are inefficient. Undersized ACs can’t cool your home to the desired level, and oversized units cycle on and off constantly, leading to other more serious problems. Learn more about which size of air conditioner is best for your home.

Blown fuses, damaged wires and circuit breaker issues can cause AC units to malfunction and stop working altogether.
Note: Always have a certified repair professional safely handle any electrical problems.

Broken capacitors cannot provide the energy needed for an air conditioning system to start up or continue running.

Replace vs. Repair Lennox Air Conditioner

The million-dollar question is: Should I repair or replace my Lennox air conditioner? If your repair bills are piling up, it’s no surprise that you’re weighing your options, but is new air conditioning installation the way to go?

In most cases, Dr HVAC can repair your AC system so that it will continue to run effectively. That being said, there are situations when installing a new air conditioning system is the best choice. 

Consider these factors before you make a decision:

  • Age of the AC unit
  • Frequency of breakdowns
  • Cumulative repair costs
  • Energy efficiency level
  • Utility bill expenses

If you are still unsure, connect with us! Dr HVAC will inspect your old air conditioning unit and let you know if there is any life left in your existing AC or if it’s time to let it go. 
We’ll also share some recent developments in technology with you. Many new cooling equipment options, like Energy Star rated air conditioners and heat pumps, are both cost-effective and energy-efficient.

How Long Do Lennox AC Units Last?

Your Lennox air conditioner should easily last 10-15 years—even longer if it’s properly maintained.

If you want to extend the life of your Lennox air cooler, invest in an annual maintenance plan. With our preventative maintenance package, you don’t have to worry about your HVAC system. Dr HVAC technicians will visit your home each year to inspect, service and make necessary repairs. You’ll also benefit from special discounts and priority heating and cooling service calls! So call us at 905-457-4425 today and enjoy the peace of mind that comes with knowing that your Lennox HVAC equipment is functioning as efficiently and effectively as possible.
