"Infinity gas heat and electric a/c"

5.0 rating
Very Satisfied

I have a two zone infinity gas furnace (40k btuh @ furnace at high fire) and infinity 21 A/C units nominal 2 tons on high but the units deliver closer to 30 k btu’s I think. They tend to run on low most of the time and the dehumidification is superb. At 75 degrees summer my home feels cooler than it did at 70 degrees with the old tempstar system, not to mention the operating cost is about 1/2 of what the tempstar system was. in fairness to the tempstar system it served me well for 17 years which I think is great. The carrier infinity furnaces keep my home more comfortable for a FRACTION of the cost it took to keep my house uncomfortably cold with my old oil steam boiler. it literally costs about 20% of what the oil burner cost to run and instead of keeping the house 60-65 degrees i can keep the house 70-75 degrees for a fraction of the cost and a fraction of the energy usage. perry hall hvac of the baltimore, maryland area did a SUPERB job installing the units and I would recommend both carrier infinity and perry hall without reservation.

"Carrier junk, poor service"

I’ve spent four days now trying to get a grip on what is causing problems with a Carrier Infinity System. The unit is installed on a friend’s home. I’m a general contractor, and the local Carrier dealer is no longer welcome on this jobsite. This Carrier unit is about 3 years old. It was installed on existing ductwork. Through my efforts, and a bunch of phone time with Carrier tech support, I’m of the opinion that this system is way over-sold and way under-engineered. The static pressure reading mechanism is factory calibrated for sea level, and does not account for elevation changes, so you have to know how much to allow for based on your elevation – not a critical issue but a hassle just the same. The “Replace Air Filter” notification is constantly on. The coil is clean, and the return ducting is adequately sized, and the supply duct is adequately sized – all according to readings taken from the controller. Even with the coil cabinet cover removed, the static pressure reads as being too high. Tech support’s recommendation is to simply turn the notification feature off, but that’s not what the customer paid for. Tech support verified the components used on this unit is a matched set, which leads me to think the coil and coil cabinet are simply too small and will not allow sufficient airflow. This design “flaw” only exacerbates any issues one might have with insufficient ductwork. I suggested to tech support that maybe the controller or some other component might be defective and giving us incorrect static pressure readings. He told me all was well and that the unit is working properly, but to just turn the dirty filter notification off and problem solved. Even with the controller set on “Auto”, the unit cycles on and off. The blower always runs on high until the unit reaches temp, then the unit shuts down completely. It acts as if the unit is running on a standard thermostat. The blower on the infinity is supposed to run at variable speed, with the compressor cycling on and off per demand – but the blower should never stop running. Tech support tells me the unit knows what it needs to do and is functioning properly – bullcrap. We only have one Carrier dealer in our town, and the homeowner does not want him back on the job. The tech support guy is tired of talking to me, most likely because I have identified the problem and there is no (Carrier available) solution. He’s tired of making excuses and covering for a design flaw. Just like the local Carrier dealer, the tech support guy is hoping we’ll just get frustrated and go away. If someone tries to sell you a Carrier, you’d best run like H*ll!

"Carrier Infinity System"

We are extremely disappointed in our Carrier Infinity system. It’s quiet and efficient, when it’s working, but that’s it. The system was installed in 2004 and is on its 3rd motherboard and 3rd blower motor/module. The most recent blower motor just went out after the factory warranty was up, and it’s not cheap. It’s ridiculous for us to have to spend so much money to keep a system going. I would not recommend a Carrier to anyone, and I will never buy a Carrier again, period.

I had a Carrier furnace installed last June. It was an Infinity Model. It is the quietest furnace I have ever had just as promised and does a much better job of warming the whole house. I also had them replace the air conditioner. I was a little upset as it was much larger than my old one, but once I heard it run I was amazed. Carrier is the quietest on my street and now all my neighbors want one too. It was not a cheap system but you get what you pay for. Make sure you ask about the size of the A/C.

We’ve Sold/Installed Many brands over the years. Carrier, Trane, Goodman, Lennox, Comfortmaker. Carrier is absolutely the best in quality, efficiency, and Customer service and support. The Infinity is the best all around system on the market hands down. We’ll never sell anything else.
