Our HVAC unit on our townhouse (3 levels and each level has it's own thermostat and appx 2200 sq FT) sprung a leak in one of the coils a couple of months ago. The guy who came out (can't remember the name rt now) put in 3lbs of freon and said it should hold for a few months as it was a slow leak. My question is, when the time comes, should we have the offending coil replaced or the whole unit? It's a Lennox that's appx 5 years old as the house was built in 2009. Would appreciate all opinions as well as suggestions for who/where to buy from and who to install.

Thanks!!

Dig out the paperwork and read about the warranty. It may be 5 years on parts.

I like Service Experts but other C-D contributors have criticized them.

The first thing I would do is find out if the coil is still covered under the manufacturer's warranty, but even if it is you might still have to pay labor and refrigerant charges to install the new coil. The manufacturer may also stipulate that an authorized Lennox dealer must do the warranty repair, but it's worth checking into none the less. Many on this forum have used Justin Woodleif but I can also recommend Robert's Heating and Air Conditioning. Robert is very honest and his prices are reasonable.

Unfortunately we do not have the paperwork as we just bought the house (we are first-time homeowners so please excuse the cluelessness last year.

So you think it would be better to repair/replace the coil rather than the whole system? Am thinking about getting quotes on both...

Thanks for your help!

Service Experts is affiliated with Lennox in some way. Find the model and serial number on your unit. Contact Service Experts, explain your situation, and ask them to determine the installation date and warranty coverage.

Agree. Check the warranty status either with a service contractor or directly at the Lennox site (I think most let you do it).

If under warranty, it makes sense to do it. If its not and your unit takes R-22 and is a 13 SEER, it starts to be come a more difficult choice, IMO, due to the rising cost of R-22. 5-10 years on if you have any more leaks it will be astronomical to recharge the refrigerant.

This is just my opinion so please take it for what it's worth, but I would have the coil replaced. I have a lennox system as well (only a year old) and it does have a 10 year warranty on parts. You'll still have to pay for labor and associated costs, but I'd rather pay $300-$400 than $5,000+ for a new unit. If your unit was 15 years old I might be inclined to recommend replacement, but you'll get plenty of good years out of this small fix and it's only going to cost you 5-10% max of what a new unit would run.

I just checked the price of R-22 and it was only a little more than R410. Plenty of it available.

My HVAC guy says the price of both has dropped over the last couple of years (I made a decision a few years ago to replace so I could have new refrigerant - but my equipment was out of warranty and >10 yrs old). Perhaps everyone swiiching to R410 has reduced demand for R22.
