Two quotes and companies we’ve liked so far.
Carrier company has been a local Phoenix company for over 40 years, good reputation. Parts and compressor 10 year warranty. 2.5 and 3.5 ton units for $13.3k. We currently have 18 year old Carrier units and they’ve been solid.
Lennox company is locally owned but only been in business 10 years but good reputation too. They tout the best warranty in Phoenix. $700 more than the carrier quote and includes 10 years parts/compressor warranty but also includes 10 years annual maintenance checks and $100 deductible on labor out to 10 years. Also they will include full duct cleaning and sanitizing if we replace both units at the same time. They just replaced our friends AC unit and they were very satisfied. 3 ton and 4 ton units for $14k.

How did the estimators determine what size units were needed? Did they simply just offer to install the same size equipment that you already have or did they do a “manual J” calculation to calculate the required cooling loads? Did they inspect the ductwork and airflow at each register in every room? I would want to understand in detail how they arrived at your system sizing, ductwork modifications and the details of the coil and condenser SEER. Also, it’s good to understand what temp they are protecting for for max outdoor temperature in their calculations. When you ask these types of details from your estimators you will begin to get a good feel for how much science vs guessing each is doing.
