I am quite pleased with HVAC Direct, your pricing & speedy delivery. I am replacing 2 HVAC central units that are both 34 years old and the main reason is the cased coils are very corroded. Both units are Carrier “Round Ones” and have performed excellent. I shopped around and found this model was made by the same group (United technologies) as Carrier. Your company has the best price and if it lasts as long as the Carrier unit, I will be very pleased.
