I'm in the market for a new furnace and heat pump to replace a 35 year old furnace. I'm in Vancouver BC and have two quotes, planning to get one more before deciding on which way to go. My house is 2900 sqft on two levels and I'm in the process of changing out the single pane windows for double pane energy efficient glass and improving the insulation.
The first quote was for a Lennox G71 with an XP19 heat pump.
The second quote was for a Carrier 58MVC Infinity ICS furnace with an Infinity 19 heat pump.
Both quotes are for 3 ton heat pumps. The guy giving me the second quote asked if I had other quotes, I mentioned that I had a Lennox quote but did not tell him the pricing.
He proceeded to tell me the following, which I suspect may be sales spin and would appreciate any advice on:
- Carrier heat pumps are much better than Lennox as they have some patented and proprietary technology that makes them more efficient. For example they will operate down to -7 degrees Celsius while the Lennox is only good down to +4 degrees Celsius.
- The ratings on the Carrier heat pumps are more conservative than the Lennox, if I go with Lennox, I should get a 3.5-4 ton unit to be equivalent to the 3 ton Carrier.
- The variable capacity gas metering on the G71 is inefficient as it will ratchet up by 5% every 5 minutes, meaning that it will take an hour to get to the optimum temperature.
- The Carrier furnace is quieter than the Lennox, although Lennox claim the opposite.
The Carrier sales person also mentioned that the only air filter system that is any good is the Trane Clean Effects. I had the Lennox guy quote on the Pure Air system, both are about the same price.
Would appreciate any advice on the truth or otherwise of these claims. I realize this is probably a polarizing topic.
Thank you !
