Carrier offers boilers with efficiency ranges from 80% AFUE to 90% AFUE*. Carrier is a popular name known for air conditioners, heat pumps, and gas furnaces but Carrier offers other types of HVAC products including Carrier hot water boilers in indoor air quality products that compliment Carriers other HVAC products.

I built a home in 2011 with a Carrier 48ES heating/cooling unit. By 2017 the units heater exchanger tubes are completely rusted and the unit must be replaced for a price of over $6000! I find it interesting that Carriers warranty only covers the unit for 5 years.

I am satisfied. I hoped for a little more efficiency, since I was replacing a 40 year old unit. It does provide very steady heat and have had no issues so far.

Just like 1800s. Beautiful heater for price and the scientific structure of craftsmanship a plus.

Saved to purchase new heat and AC. Bought July 2018. So excited...finally not having to call and have our old heater fixed regularly (GOODMAN). At first it was so quiet, then one month later it is noisier. Okay were fine with it just nice to have air. Now our troubles begin...HEAT. When we put the heat on for the first time, you have a smell, normal, especially after sitting for a few months, not in use. Our rec. room is downstairs as well is our office. We can smell a chemical/chlorine, gassy smell. Way ahead of you. Called gas company, called installer and checked my monoxide detector. NOTHING. No leaks, they found no odor. Everything is running top notch and fine. Okay, now. We sound crazy but at night, there is a smell of gassy, chlorine, chemical.I looked online to see if others had this problem and they do... I called Carrier and they offered no solution or tell us what it may be. It is Jan. 24th 2019 and I am typing this review with a smell of gas, chlorine in the air. I feel sick to my stomach and have a headache. We get a sleepy feeling when we shouldnt be tired. We are extremely MAD that this is happening. We have monoxide, gas detectors on all floors, one right next to the unit. We checked this so often, we have a new hobby. Sickening... I wish we never bought this and I wanted my old Goodman back.
