Is it noise?

Asked by: irene
Actually, my response is to the tech. Noise is not relative, it's absolute, measurable at the source. You could have told him something like 76 decibel at 3ft. The he can determine if that is loud for his preference.

100,000 BTU 95.5% Multi-Positional Gas Furnace is rated 4.6 out of 5 by 5.
Rated 3 out of 5 by from Solid performance difficult installation The installation of the product is not something to be taken lightly. expecially if you are using downdrafting for your ventilation. This is a selling feature of the product over the typical stack mounted venting systems but it creates water as a byproduct. There isn't one but two water exhaust's on this machine and one requires a pump to move the water upstream. This isn't stated in any documentation I've seen. This all being said the fuel use is excellent and the heating ability once the system quirks were figured out is quite good. I would recomend this if you are exceptionally handy. If not get an installer who knows this type of system or you'll have allot of callbacks.

Rated 5 out of 5 by from Happy Camper Ordered the 120K unit. The company rep called me and reviewed my needs. Changed to 100K unit. Purchased the LP gas conversion unit. I wanted to install it myself. I read through all the instructions several times, and had a licensed installer review everything I did. I not sure if he was surprised how good the instructions were, or if he was shocked by how closely I followed them, but everything went great. Changing from natural gas to LP was not a problem. I even bought a manometer to keep an eye on the LP gas pressure since I've never used LP before. The furnace worked the first time it was turned on. I purchased it in Oct, but family health issues delayed the installation. It went into service on 12/21/12 it has kept us nice and warm. It had a cosmetic dent from shipping, but I just straightened it out.

Rated 5 out of 5 by from This is a great furnace! This was a great replacement of my old lennox. It is a nice compact size. It was a pretty simple installation overall. I converted mine to LP which does require a manometer to set the gas valve pressure. The instructions were very detailed. It is very light, I think it weighed 70 pounds on the pallet.

Rated 5 out of 5 by from This product is well built. Also compact for what it rated to put out. Works well doesn't take long to heat up an 1800 sq. ft. garage.
