Overview of the HS26

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.

"Best unit I have ever bought"
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"
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!"
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."
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!

"Lennox Leaking Coils"
We have 2 units in our home: 1.Purchased hs26-060 8/26/05 & 2.Purchased xc15 Model 8/28/07. In October 2011, installing dealer found both units coils leaking refrigerant and recommended replacement. Both units are covered under a 10 year warranty so replacement now will cost us nothing. However, we are concerned because the dealer wants to install uv lights and humidifier in both systems at our expense saying this will eliminate the problem of coils leaking. More importantly, we are concerned about our exposure after the warranties expire.

The worst ever! Do not ever buy it…. It will be a very costly mistake. The company will not help you with anything. If the house comes with a Lenox unit, DO NOT BUY THE HOUSE – the unit will go down. The compressor went down every year, even if the compressor is in warranty you will still have to pay as much as the compressor is for labor. On the top of that they do anything they can not to refund the contractor for the bad compressor. The worst company I have ever dealt with producing the worst and the most not reliable products. On the top of that every contractor in my area that I have talked with do not like dealing with them.

"Nothing but Trouble"
This unit ran great for the first couple of years then went straight down hill from there. Although I get routine maintenance twice per year it still performs poorly. Always something wrong every year there is an expense Capp went out, then blower motor went out, then something else all the time. Now R22 leak is the latest some minimal warranty coverage but a very poor quality product. I will never buy another Lennox! You couldn't even give me one.
