Browse Forums Heating, Cooling & Insulation 1 Feb 21, 2011 4:39 pm Hi, We have just purchased a home built in the 70's and want to have the old Gasglo ducted heating and Weatherwall A/C replaced. We have been quoted $4440 to have a Lennox G61MPVT-60C-110 replace the old heating unit and using the existing ducts. The system has a max output of 30.5kW. To add on cooling (Lennox TSA-065 17Kw 3 Phase) the price will be $6840. Is this a reasonable price? Does anyone have a Lennox system installed and are you happy with it? Re: Lennox ducted replacement quote 2Feb 22, 2011 3:53 pm Is it an extra $6840 on top of $4440? unless you have the bigger ducting as standard it may not work properly. The bigger ducting is required to get the right air flow through the unit. If it doesn't flow enough the unit will simply freeze up. I have a good mate who is a lennox distributor and I can't sell me the required bits for that price of $6840 alone. One downside to Lennox stuff is that its big. Really big, they need extra room around them as they have quite large profiles but still need a minimum space around them to work. Is it ducted heating in floor?

The ducting is through the floor on the first floor (5 vents) then from the ceiling on the second floor (4 vents). Looking at the quote again, it looks like $4440 is just for the heater change over and $6840 is for the added refridgerated aircon. Is this still an OK price? They will connecting to the existing ductwork. Just be careful with building stability during construction, that is when the structure may be weakened, refer to your engineering drawings for stability methodology. 1 7224 Can anyone recommend a good/affordable retaining wall and fence builder that I can get a quote from located in Sydney? 8 45802 Last year I had a gas leak at my house. 3 days later, I have about 1 sqm of my exposed aggregate paving broken up.
