Ever since we purchased and moved into our current townhome in 2005, we were making plans to get rid of the 23 to 25 years old HVAC system in our home. The old compressor unit can barely keep the house cool during the summer months in NJ. As for the gas furnace, the carbon monoxide leak my good neighbor experienced haunted me night after night. Finally, after 2 1/2 years, we decided to go ahead with the work. First, we contacted 3 companies for estimates. The outfits we contacted were the utility company, a big box store, and a small local contractor. We only received 2 estimates. Apparently, the local contractor would not provide us with a quote unless we can make same day decision. Anyways, in the end, we went with the big box store. There are many reasons behind the decision (price, warranty, impression of the sales person, etc).
The contractors from the big box store performed the installation yesterday. The furnace is Trane XV80 (2 stages with variable speed fan motor). The compressor unit is Trane XR13 (2.5 ton). I am not too sure about the indoor coil though. While I am absolutely no expert on HVAC system, I feel the installation (furnace) MIGHT BE a bit sloppy. And, I also have some concerns after the installation. But first, here are some photos.
Here is the XV80.
Here is the joint between the indoor coil and the furnace. (Notice the sealent)
Here is a full view of the indoor coil. (Notice the burn mark & putty)
Here is a full view of the compressor unit. The contractor quoted us with the XL15i. However, the unit might be too large to the liking of our HOA and next door neighbor. So, we decided to go with XR13 instead.

Here are my questions..
1. Right after the completion of the installation, I noticed that air leaks from the duct work joints, indoor coil, & even the furnace itself. I raised this concern with the contractor. He told me that air leak is common since the system is full of holes everywhere. He did apply more caulking here and there afterward. However, there are still plenty of air leak everywhere. So, should I be concern about this? Or, perhaps this is normal as stated by my contractor?
2. If repair is necessary to address the air leak problem, is it ok for me to purchase some HVAC tape to do the job myself?
3. What do you pro guys think about this installation?
Anyways, sorry for the long post. Thanks in advance for your input.
