"Great job and the technician did a excellent job advising how to maintain my system."

"I called Coolray to make an appointment to have our ducts checked as there are two upstairs vents that did not have good air flow. Our mechanical room which houses our HVAC unit has also been very cold and the pilot light on our water heater which is in the same mechanical room keeps getting blown out. I spoke to Erin and explained the problem stating that it seems like one of more of the ducts may be leaking air into the mechanical room causing the water heater pilot light to be blown out frequently and resulting in poor airflow to two of the upstairs room vents. Erin scheduled an appointment for the next day with a senior technician, Tom Nguyen. Erin called me the next morning to state that he was delayed at another job and provided a new estimated arrival time. Tom Nguyen then called to let me know that he would arrive withing 30 minutes. When Tom arrived, I explained that the living/dining room and one of the bedrooms do not get much airflow from the floor vents. Tom felt the flow at these vents and then went down to the mechanical room to inspect the HVAC unit and the ductwork. He said that the cool temperature in the Mechanical room around the HVAC unit is perfectly normal and does not mean that there is any kind of leak in the duct work. He checked all the ductwork and found all properly connected with no leaks. Tom determined that the airflow from the kitchen vent was stronger than the rest. Tom closed the damper to the kitchen allowing more air to enter the bedrooms and living room. Tom checked the air flow in each room and found that the system was doing a better job cooling the living room and bedrooms. I appreciate the time and effort Tom took to understand and find a solution to my problem. Tom was very professional, polite, friendly, and knowledgeable. He solved the problem quickly and efficiently. I received a voice message today from Erin asking whether we are completely satisfied with the work performed yesterday. I am grateful for the excellent customer service received from both Erin and Tom. I will happily recommend Coolray to any family member or friend in need of cooling services."

"I've used Ace & A for 20+ years for both heating and air installations and service. The staff is helpful, reliable and competent. I always have annual service check-ups, and they're good about keeping older equipment running smoothly. When the time comes to replace my systems, I'd definitely consider using Ace & A."

"Estes performs a furnace and air conditioning inspection each year. They are professional and do excellent work. As a result of an inspection, it was determined our furnace couldn't be used. They replaced it. At least 6 years of excellent service."

"The cost was $5200 for the installation and the device as well. It was excellent service. They did more than just the installation. I didn't know this, but when they give you a new air conditioning unit and heating unit, is essentially, they bring the components out and actually assemble it out in the yard and they out it up in your attic. I found them from a third party and they inspected it with Jones Climate Control. The two of them worked as a team to see what I needed. They took measurements to figure out the size of my unit, they gave me an estimate for what I was going to need for my house, then they went ahead and devised a plan, not only for the new unit for the upstairs, but also devised a plan based on what I told them about inadequate air flow to remap the ducting. The price included all of that. Then, what they did was, after they did it, the third party wrote out the contract by hand and then he ensured that he could actually read it, went over it line by line, to make sure I could read it, and based on that, he told me who the install people were going to be and what the price of the regular maintenance price was going to be. They did run into one tiny little hiccup at the end. They were going to put in a new register on the upper floor because they had actually put in a new duct, I guess, in the hallway section and the register wasn't the right size and the guy said he'd come back later that week to go ahead and put it on there. I, of course, was afraid that he wasn't going to do it because at that point it was a small item, I think they had been paid, so I called the third party because he followed up and called back himself two days later to see how they did. I said, "They had done a decent job, but they didn't have the size of this and I'm not sure if they are really going to come back", and he said, "well, I'm going to have a few words to say about that", and sure enough, and I'm not saying it was because of the third party said, they did come back as they said they would and they finished up on time."

"I highly recomend this company, they are professionals, very knowloadgble from customer service to the technician Leo that prefomed the services on our air duct and dryer vent."

"I couldn’t have asked for a better company or a better person than Henry to do the job. He was “over the top” in his attention to detail, his kindness, and his professionalism. Casteel had just completed some plumbing repairs and after a very scary experience with the company who had been servicing our AC/heat for years, we are now putting all of our electrical, plumbing, heating and air needs with Casteel. I cannot rate Henry or Casteel highly enough.7"

"Very well. Excellent service. Very trustworthy."
