In most cities, every building uses a type of HVACR system, irrespective of whether it is a residential or office building. In 2013, MARS also acquired Heat Controller Inc.

It is a brand that has lasted about 80 years of providing both room and central air conditioning systems, quality home furnaces, and commercial heating and air conditioning products.

These Air conditioners come with an R410A refrigerant horizontal system, an ultra-quiet operator, an impressive ten-year warranty, and a compact design to save space and make moving and installing the AC units more convenient.

Is Comfort Aire a Good Brand?

Comfort Aire is one of the best brands you can find in the industry. It is a top producer of dehumidification, heating, and cooling products. It is a division of Heat Controller Inc.

based in Jackson, Michigan, and began manufacturing air conditioning systems and dehumidifiers.

Comfort Aire products are tested and trusted for their durability and reliable performance. They are also good at conserving energy.

Comfort Aire produces a wide range of highly geothermal heating and cooling solutions.

Comfort Aire also has more humidity control than many competitors, as it is a critical feature in its design.

In addition, it is sensitive to dryness in the air and can regulate the coldness of its blast to match the environment and maintain comfort, so the room remains in a satisfactory state.

Is Lennox ACs Reliable?

Lennox brands are reliable because they consume low energy, reducing homeowners’ costs. Unfortunately, Lennox is a premium brand, so it has one of the highest costs in the industry.

However, Lennox is very efficient; the 28 SEER SL28XCV unit saves the average homeowner $3060 in 15 years through lower energy costs when replacing a 10 SEER AC.

SEER is an acronym for Seasonal Energy Efficiency Ration. It is a rating system that allows you to determine an air conditioner’s energy efficiency quickly.

The top Lennox line is the Lennox signature series, an excellent customer choice. The middle group of the Elite Series ACs varies from excellent units with a 10-year warranty to other models with 5-year warranties.

Even with the excellent features, customer feedback, and ratings Lennox products have, there are pros and cons of the Lennox Air Conditioners you should consider when weighing your options.


#1. Energy Efficiency

Lennox offers the most options for super high efficiency, and the SEER ratings and energy conservation gap between it and its competitors is quite significant.

It is eco-friendly, and it reduces energy use. The minimum SEER rating is 13, and Air conditioning systems with SEER ratings within 13-15 are considered primary. 

They do not save as much energy as ACs within the 16-19 better range and the 20-24 best range.

However, Lennox offers models with SEER ratings as high as 28. A high rating saves the owner a lot of money and reduces environmental damage.

#2. Broad Offers

Lennox is the most expensive in the market, but they offer a range of product options that encompass low-range, mid-range, and top models.

The Lennox brand can accommodate any budget. There is a Lennox for every budget.

#3. Superior Parts

They have an aluminum quantum coil which is a superior coil with a meager failure rate.

In addition, Lennox has a lifespan of 10-15 years, and it can last even longer if meticulously maintained, so the AC parts are high quality.

They are of superior materials designed to work continuously for long periods without fail.

#4. Quiet Operation

Not only do Lennox Air conditioners bring satisfaction and comfort, but they also do so without any noise.

The system is one of the quietest on the market, and you can run your AC at full blast without worrying about noise.


#1. Generic Repair Parts Don’t Work with Lennox

You must get Lennox parts when you want to repair or replace a Lennox Air conditioner.

These Lennox parts cost more than generic AC repair parts. You can not use a general AC part for Lennox repairs because it will not work.

In addition, the Lennox supply chain is notorious for being extremely slow, so it might take a lot of time for your repair parts to get delivered.

It might cause a problem to last up to a week before repair when you can fix the same problem on another brand in just a day.

#2. Scarce Lennox Parts

Apart from Lennox supplies repair parts very slowly to customers, getting an available Lennox part is also challenging.

This fact, combined with the other disadvantage of using a Lennox AC, can pose a real problem.

#3. Large Condenser Size

Lennox units are pretty large. There has to be enough space outside to install the condenser unit, or it will pose a problem.

In addition, moving the Lennox units might cost more than average due to their size, which adds to the already high cost of owning a Lennox Air conditioner.


Selecting a brand solely depends on the specific features you need or desire because both Comfort Aire and Lennox brands have advantages and disadvantages of using either of them.

Also, check the warranty length when discussing AC models with a salesperson. Going for the best warranty offer and SEER rating will benefit you.
