Lennox HS26 Central Air Conditioners | FurnaceCompare®

Lennox HS26 Air Conditioner Overview

The Lennox Elite HS26 is a high-efficiency residential split system condensing unit with a cooling efficiency of up to 14.8 SEER. The HS26 is made with a Copeland scroll compressor for precise temperature regulation. All units have a single-phase PSC fan motor and a high-efficiency outdoor coil providing low air resistance. Such features have enabled this Lennox unit to reach Energy Star compliance.

According to the m manufacturer, sound production during operation is reduced in the HS26 by the insulated compressor compartment. Additionally, the direct-drive fan is optimally balanced for quiet function. These features, as well as the use of sound dampening materials, are part of the HushTone design in the Lennox Elite series, which is intended to minimize vibration and keep operational sound production below 74 decibel.

With a corrosion-resistant cabinet and baked-on finish, the HS26 is made durable to weather extremes. Lennox suggests that the unit’s reliability is enhanced by the integration of the line’s heating, cooling and indoor air quality products. The HS26 unit can be mounted on a slab or rooftop and refrigerant lines can be installed vertically or horizontally.

"22 MN years & still cooling"

5.0 rating
Very Satisfied

This unit was installed in 1995. It has cooled my house (app. 1600 sq ft) smoothly for 22 years. Only trouble has been a disconnected wire. I have the Lennox maintained via Centerpoint Energy on an annual basis.

"Best unit I have ever bought"

5.0 rating
Very Satisfied

I have had this central air unit for 19 years and today, July 1, 2015, was the first time that I ever had a problem with it. I replaced the condensing unit fan motor and also installed a new run capacitor. Atta boy, Dave Lennox. Very happy consumer and hope that your newer products are as good or better than this unit has been for me through all of our very hot north Texas summers.

"Didn't make it to 10 years"

1.0 rating
Very Unsatisfied

We bought it in the summer of 2005 and it stopped working at the end of 2014. The problem was a failure in the coils that resulted in total leakage of the refrigerant. The tech said that repairing it is a lost cause. The warranty covers the compressor parts (not labor) for 10 years, but the coils fall into the five year warranty period, so this is all on us. There is also a class action suit starting against Lennox because they allegedly knowingly use inferior material on the coils, which too often leads to this problem. I will be looking into that. I expect a central A/C to last 15 years. I'm not buying another Lennox.

"19 Year Old HS26-411 Just Died!"

1.0 rating
Very Unsatisfied

My 1994 Lennox 3-ton AC unit just died. That being said, it was never cleaned, never serviced, never touched since it was installed in 1998 as a 1994 leftover. After the heat wave in July, it stopped. I replaced the blown out capacitor and contactor and now it will turn the blade motor and compressor on if I manually click the contactor switch. It leaks oil and thus freon. A Lennox dealer came out and gave me quotes to replace of 6,000, 8,000, and 12,000. I can't afford. Did not tell me about dry charge units cost $896 from HVAC.com. But, 19 years of trouble free use. The unit does not owe me anything. Builders grade Aire-Flo may be the answer. If you can afford it and can pay a reputable installer, get the Lennox new latest and greatest 25 seer. If not, Aire-Flo sells for half but it is made cheaper. You can get a ten-year warranty with the Lennox but only 5 years with Aire-Flo for a reason.



"Not always equipment."

5.0 rating
Very Satisfied

Just a word to the wise. No matter what brand equipment you have installed, if not installed properly problems will occur. With the new a/c refrigerant,410A units are not compatible with older r22 systems. You can not put a new 410a condenser ( outside unit) with an older r22 blower coil (inside unit). Also refrigerant piping should be replaced. Oil in new units are not compatible with oil in older units. Noisy units. If whistling is coming from blower or furnace, this is not necessarily equipment problem. Could be sign of inadequate air flow which is caused by to small duct work, not enough supply or return. Yes Lennox as all manufactures have problems time to time with there equipment.But also many of these problems are caused by equipment installed improperly. Know who your contractor is!

Other HS26 Reviews

There are mixed reviews on the web about the Lennox Elite air conditioner series. Many reviews are quite positive, especially regarding the unit’s quiet functioning and money savings. Complaints of the product are linked to the quality of installation while others are parts-related.

Among those parts complaints is one posted on consumer forum justanswer.com, in which a homeowner notes that his 10-year-old air conditioner suddenly began making a loud noise during its run time. A consulting contractor ultimately discovered that the unit’s compressor had begun to fail.
