Recent Review: We recently purchased a new heat pump/ac unit from Day & Night and couldn't be happier with this company. To start, Brian, the salesperson, arrived on time to provide an estimate. He conducted a thorough review including inspecting ductwork, measuring the square footage of our home and utilized computer software to calculate the proper size unit we needed (we have only been in our current home a few months and discovered the current unit was too small to keep the house cool when the outside temps climbed above 100). Brian was friendly, professional and knowledgeable, explaining everything in terms a layperson can understand. I want to add that other companies provided an estimate after merely looking at the home's square footage. They did not bother to look at the duct work. Had they done so, they would've found what Brian did: A need for some adjustments and a total lack of insulation in several areas. We decided we wanted Day & Night to do the job. They next scheduled a technician, Peter, to come out and take a look concerning the ductwork and other technicalities. During his review, Peter spotted a hidden potential hazard concerning the current electrical configuration. We were grateful to Day & Night for spotting the problem which they fixed during the installation. We were able to get the job scheduled within just a few days. The crew that arrived, Josh, Tony, and Cameron, like everyone at Day & Night, arrived right on time at 6am. All three were friendly and hard-working. They even brought (and installed in a back bedroom) a portable air conditioner so that we would be comfortable throughout the day while they completed the installation. They also carefully laid drop cloths knowing they'd be working on ductwork that might kick up dirt/dust. The three kept the pedal to the medal, and by about 1:30 pm, they were finished. And by "finished", I mean they gathered all their equipment, disconnected the portable a/c unit, and thoroughly vacuumed the floors just in case any dust escaped from the drop cloths. They could not have been more thorough. I can't say enough good things about Josh, Tony and Cameron-- they were absolutely great! One week after the installation, it is Day & Night's policy to send another person to inspect the system and installation. Carey came out and I found him to be friendly and knowledgeable, like everyone at this company. He saw a minor issue with one of the parts on the unit-- they'll be out in a couple days to fix it. It is nothing that is impacting our comfort but Carey was not happy with the part and wants it corrected. I've lived in AZ many years-- this is the fourth or fifth new heat pump/ac unit I've had to purchase. My experience with Day & Night was the best of all. These people know what they're doing and it shows! The quality of the unit itself is of course important but it is even more important that the installation - including proper ducting, etc - is done correctly. For that reason, I am glad we chose Day & Night. I will never use any other company for our a/c-heating needs. If you're seeking high quality -- from the schedulers to the technicians -- go with Day & Night. You will not be sorry.
