"Model #58MEC080-12"

1.0 rating
Very Unsatisfied

I had a Carrier 58MCB high efficiency gas fired furnace and air conditioner installed on 9/2010. The motor was bad and had to be replaced on 9/2013 only after three years. At a cost of $435.00 to me. The original Carrier 58 series, single speed motor was still running after 27 years. I would not recommend the variable speed motor to anyone.

"Base 90 Gas Furnace Model: 58MCB – Defective Part"

1.0 rating
Very Unsatisfied

We’ve had our Carrier Gas Furnace for 4 mths (albeit the base model), and already had a defective part (Pressure Switch) replaced. Apparently, the technician himself replaced about 40 of the these parts this past year, never mind how many the other technicians replaced. So, how long or how many more defective parts will be replaced before Carrier does something about this and probably other problems. And to think we replaced a 23 yr old Lennox furnace (no problems at all) because it was recommended that for resale purposes it’s better to have a high efficiency furnace (whatever the series).

"“Bum” Furnace"

1.0 rating
Very Unsatisfied

I bought a new home in 2007 with a new Carrier furnace; I had anticipated a good working furnace for many years… So far, I’ve had to bring a Technician in twice because the furnace had broken down…the 1st time was to replace the motherboard, the 2nd time was to replace the blower motor. This furnace has cost me hundreds of dollars (warranty covers parts only and registered Carrier service Technician costs are ridiculous) in repairs already and it’s only 4 years old. My warranty expires next year, and I’m dreading what the cost of this “bum” furnace will be then.

Other 58MCB Reviews

A thread on reveals a discussion about different Carrier models, including the 58MCB. One expert says that, even though the 58MCB is a base model, it is part of a high-efficiency series and is a quality product. Another contractor points out that technicians often quote base models because most homeowners want the lowest price possible.

A potential Carrier customer asks on whether or not it would be worthwhile to upgrade from the 58MCB to a model with a variable speed blower, as the 58MCB has a single-speed blower. An expert comments that a variable speed blower provides more comfort and is therefore worthwhile, but it is up to the customer to decide on paying the price difference.

A Carrier 58MCB owner writes on that his blower has been running nonstop in the two months since installation. He had consulted a technician, who did not know why it was continuously running. An expert on the site explains to the owner how to disconnect a wire in the control panel, which will reportedly make the blower run only when the furnace is heating.
