I have a Lennox pulse furnace that is 23 years old and a Lennox A/C that is 22 years old.
My question is: should I replace them for newer equipment before they break down, or just run them into the ground. The price of hydro keeps going up. They get serviced every second year.

I live in Kitchener, Ontario

KEEP THE PULSE, if maintained a Lennox pulse will last you a awhile, and they are just as efficient as a lot of the new stuff on the market, you may want to replace the A/C if you are looking to save money, however, you may not be able to install an air conditioner over 13 seer because of the way the pulse is setup, you can, but you won't get the full savings from the new unit.

If I keep the Lennox pulse furnace should I buy a new Lennox air conditioner, or shop around , i.e. Rheem, other?

If it ain't broke, don't fix it. Today's stuff is more efficient but it's more expensive. Look at the numbers. You have lotsa options.

Not knowing if your furnace is gas or electric,, if gas when they get to be 18 to 20 years old I start to get concerned about the heat chambers starting to rust or burn out when they get that old I tell people to consider a carbon dioxide monitor, they don

wmproop, you are obviously not too familiar with a Lennox pulse furnace, they did have some problems with heat exchangers in the 90's, but if maintained you can easily get 30 years out of a pulse, I have personally seen them that old and running like new.

The heat exchanger on this furnace was replaced under warranty in the nineties by Lennox.

Make sure on the next and every service they check the heat exchanger for cracks and holes. They should also check with a monoxer or similar sniffing tool to check for CO. I would also highly recommend buying a quality CO detector for your home just in case. Lennox Pulse has been known to be a problem child and it does not make a difference when the heat exchanger was replaced.They can go bad in one season.

[wmproop]

Yes,, hvac1000 is correct,, the 90`s was only 7 or so years ago,, is better to be safe than sorry,, the guy did say his unit was 23 years old

[hvacservicetech_07]

I agree, a pulse should be checked out EVERY year, but it's very reliable, and If you aren't having problems with it, don't replace it. I know people around here that are willing to pay pretty get money to find a good used pulse.

[hvacservicetech_07]

They had problems with heat exchangers for a few years but they offered free replacement or a new G26, but you have to pay for installation. I don't care what brand name or style gas furnace you own, you should always keep a good working C/O detector in the house, and every furnace should be reguraly serviced.

[NorthernHeat]

Yes the pulse had it's share of problems, as long as it is safe keep it. Repair parts recently have been astronomical, so if a major repair becomes necessary you may want to replace it.

[hvacservicetech_07]

I agree with you there Northerheat, but honestly, isn't everything getting pretty high?

[NorthernHeat]

OK, over thirty percent of replacement cost, just replace it.

[hvacservicetech_07]

Northernheat, sorry I wasn't trying to undermind or argue with you, I was just trying to spark up a conversation, no disrespect.

Don't worry, I don't get offended that easily. :D

[Grangy27]

After considering my options I bought an Aire-Flo AF92 to replace the 23 year old pulse furnace as I did not want to put any money into it. As for an A/C, I bought a Lennox 14ACX. As these are not high-end purchases, I hope that I have made the right decision.

[hvacservicetech_07]

In my opinion, the Aire-flo was not a great idea when you had a pulse, but it's your money. Good luck with everything and let us know if you have any other questions.
