"Good Unit but unresponsive company"

4.0 rating
Somewhat Satisfied

I own two Lennox heat pumps. I wanted to find out the lowest effective temperature of operation. Called Lennox, could not tell me. Called their Technical Service phone number and was told they can't tell me that information. Only a dealer can receive that information. My reply was I can be the responsible party to pay for the two units but I can't get an answer to a simple operational question. The answer, Yes. Not good company service.

After much research I chose to upgrade my 45 year old furnace and eight year old heat pump with Lennox end of December 2006 costing $6200 installed. The xp-15 heat pump had a system operations monitor, which sounded like a plus. Musts were energy efficient, quiet, and new refrigerant (which wasn't required yet. But I wanted, at additional cost of $500). With new system, winter and summer bills dropped $50-$100 month. The heat pump unit at 63Db is very quiet; inside house with new Lennox Elite furnace, unless you see something by vents moving, wouldn't know it was on; everyone comments on it. Now for the bad – for the first three years, every season change there were problems; adding up invoice costs for that time totaled about $700 for replacement of txv valve, coil, defrost sensor, defrost sensor coil. Apparently the sys. Ops. Monitor wasn't very helpful, lol. Finally repairing a crossed wire in H.P. (so tech said) fixed it. Viola, that was the last of seasonal repairs. After 2 1/2 yrs. Of quiet, efficient heat and a/c, Feb. 2015 was 1st repair needed at $479 to replace defrost board in H.P. I've paid for a maintenance pkg. Yearly with a great local HVAC company, giving me priority service (a must!) calls, reduced rates and a furnace and heat pump tune up. The H.P. is 10 years old now, I'm hoping it is as good as my next door neighbor's, her Lennox is 17 years old and works great. I'd be hesitant to buy a Lennox H.P. again because, based on reviews, sounds like blades are plastic and ice up – we get cold in Ohio. I'd look at Trane, as neighbors and friends have had very good luck with their units, and they are reasonably priced.

"Inferior unit"

1.0 rating
Very Unsatisfied

This was sold to me as the top of the line unit. "Better than any other brand on the market". I've had to have motors replaced and now the condenser is shot. All of this breakdown is within the warranty period. Sure the part will be replaced at no cost but the labor is outrageous, which I would have to pay. I've had Spring and Fall check- ups on the unit since it was installed. Lennox should be ashamed to sell this unit. With this poor quality Lennox should cover the labor or replace the unit. PS: There was very little reduction in my electricity cost.

"Lennox breaks down every 6 months."

Purchased a new Lennox furnace and Lennox xp15 heat pump in 2007 from Brennan Heating and AC. Brennan has been quite good. But the heat pump from Lennox has been a dog. I literally need to have a service technician out every season (twice a year in winter and summer) to fix/repair/replace parts/re-seal/add refrigerant. When it gets cold and I turn on the system the heat pump moans and chokes and wheezes and I need to call for service. When the temperature gets hot and I turn on the ac the heat pump sputters and locks up and I have to call for a technician. I would never buy a Lennox heat pump again.

"Doesn't work. Don't buy!"

Very Unsatisfied

This Lennox heat pump was in the house we bought about two years ago. We lived in Oklahoma that time and we didn't really get high temperatures that require continuous air conditioning in the summer. That's why it took us so long to realize that the heat pump wasn't working at all when we moved in. We later called the furnace company to repair it and they did fix it for that time and it worked for about a month after that, then it stopped working again and until now we have given up because it doesn't work at all. No real explanation for why it had shut down on us, except "probably something to do with the electronics". It worked for one month and I remember we spent about $2000 to get it working for a month and that's why we gave up trying again. I definitely would not recommend this pump to anyone who would depend on it for AC purposes.
