Carrier, a subsidiary of United Technologies Corporation, operates manufacturing facilities that make heating and air conditioning units in over 170 countries. It is no secret that quality, service and a well-trained staff are foremost on their list of priorities.
Carrier’s most basic model exceeds many competitors with an 80% Annual Fuel Utilization Efficiency (AFLU) rating that measures how much energy is converted into heat versus how much escapes as exhaust. It also features the Quietech noise reduction system, a 20-year Serpentuff heat exchanger limited warranty and a 10-year parts limited warranty. Fitted with a single speed blower and a Thermidistat thermostat, you can expect this unit to deliver 44,000 to 154,000 BTUH. Not bad for the most basic of styles.
The top of the line unit is one of the best that you can get on the market today. The Infinity ICS Modulating Gas Furnace is an ENERGY STAR partner, has an AFUE of up to 95% and has a variable speed blower. Noise reduction is rated at 100%, primary and secondary Serpentuff heat exchanger and the Infinity Thermidistat Thermostat with the Ideal Humidity System for exact comfort. 60,000 to 120,000 are the BTUH capacity.
Ten different models fall in between of the base unit and the Infinity ICS that trade off different features from 80 to 95% to the Infinity thermostat and noise reduction. If you have family members who suffer from allergies, it would be a good idea to choose the Infinity ICS. If your concern is just keeping your home warm, all of their furnaces are more than adequate. An 80% unit will cost less but measured in the long run, not really. You may want to visit a showroom to listen to the degree of noise reduction versus money. The noisiest model may be ten times quieter than your existing model.
Any model that you choose will not deliver what is presented unless you take steps to seal off any cracks in your home to prevent the escape of heat. Pay particular attention to drafty windows and air coming in from around your doors. If you can feel the cold coming in, that’s a sure sign that heat is going out.
