Replacing two 10 year old Rudd Heat Pumps. It has come down to two quotes. I am comfortable with both quotes. The Lennox quote is about 2 grand more but it is for 21 seer units. The Trane units are 19 seer.

This will be a clean install as nothing in the house is done properly now. Outdoor units will be moved to get them away from the Patio and to a more protected area.

What say the inmates. Is there an advantage of one over the other. I am comfortable with both installers.

So two quotes. Can't each AC guy quote both brands. Or are they married to one brand or the other.

Lennox guy will only install Lennox. The other guy has choices but Trane is his choice for high efficiency

Most of the internal parts are the same. Go with the higher efficiency.

I have a new Trane 19 and it cools our house with ease.


Old Trane pulled 26 amps fully loaded.

New Trane 16.1 amps fully loaded.


E Bill went way down her in Havasu.

Lennox would be my choice between the two. I have the 20 seer maytag and in my opinion that is the best high efficiency system out there and utilizes standard thermostats [emoji106]

Are you installing any zone dampers / controls? If so, I'd go with Trane.....Their latest multi-speed communicating systems are top notch. In the commercial arena, I always had good luck with Trane controls. Both excellent Brands either way....

Not sure of the difference. Did a whole Trane package about 12 years ago. Best decision ever.

He said that if you are buying a quality system (both of those are) that the installation is super important for both efficiency and longevity.

Jeff,

With respect to energy efficiency, here is the math. With respect to quality, no idea.

SEER is just like MPG but for Btu's per watt.

Take the Btu divide by the SEER and that is how many watts that uses in an hour of operation.

Let's assume they are 3 ton units.

36,000 Btu's divided by 19 = 1,894.74 watts per hour. Divide by 1000 and you get 1.89, lets call it 1.9 KWH which is what we see on our bill. In effect, that unit uses up that much energy. If you are on SRP like me, assume after all the costs and fees your average cost per KWH is about ten cents. So that thing costs about 19 cents an hour to operate.

36,000 Btu's divided by 21 = 1,714.29 /1000 = 1.714 or about 17.14 cents per hour.

Bottom line, the higher 21 SEER saves you about 1.86 cents every hour of operation. So if each unit is 1,000 more and they have identical warranties, blah, blah, blah, it will take about 53,763 hours of operation of that unit to get back the 1,000 bucks excluding cost of capital. :D

so thats about 2237 days if ran full time , which is 6 years...

so probably gonna run the thing 1/3 of the time? which will be 18 years?

so this unit is $2000 difference , which will double these numbers

I've never seen any data for Arizona but I remember some Florida data where the industry calculated that the average Florida heat pump ran for 2,500 hours per year.

Personally I would buy the 19 seer and put 1000$ into attic insulation it's amazing what an additional 8 inches of attic insulation can do. Also look at radiant barrier if you don't have it. Night and day difference.

Average comml run times in so cal are in the 2k range..... I would assume AZ is close to that.
