It took 5 days  and went very well.  Jesus and Juan were hard workers and nice to have around. 

When Duke initially evaluated the house, he pointed out some reasons the old furnace system was inadequate and corrected these problems so the house now heats quietly and evenly, which is a nice change.  2 of the air returns were redone and an additional one added to improve circulation. The associated ducts in the attic were upsized which also helped. All the old crawl space duct work was replaced with a modern version and the associated register covers replaced..

"I used them a few years before for another heating problem. They are not cheap but they are not over priced. They are reasonable. They are not the cheapest place in town, but they are reasonable and they do good work. I can't give them an A on price because they are not cheap. I would use them again."

"Air conditioner was blowing ambient air only. Tried to contact my usual HVAC company and they were scheduled out 3 weeks because of the recent heat wave. I called 14 companies to check on availability and Comfort Energy was the only one who had an opening within the week. I confirmed with them and was very pleasantly surprised. They confirmed not only the day and time, but also the exact make, model, ans serial number of the unit to ensure they had all the information they needed. In the meantime, my husband was able to get the unit going by installing a new capacitor himself, which he had done in the past, but wanted to go ahead with the service call so we could have the whole system checked out in case there were other issues. The day before the appointment, I received a text confirming the appointment time. I asked that the service technician call 30 minutes before arrival, which he did. The technician, Nasser Pineda, is a fine representative for his company. He was polite, respectful of both my husband and me, and took time at the start of the service call to go over what he would be doing and how he hoped to provide us with the best service we had ever had. He said that the goal of Comfort Energy was to provide us with service above and beyond expectations. He did not fail us. He even wore booties so that he did not track dirt into the house. My husband followed him around asking questions and he was patient and knowledgeable. Nasser also told us about their yearly service plan which would ensure service checkups before the heat of the summer and for the heater before winter cold months. That, plus the guarantee that we would get priority appointment times even during heavy demand, has clinched our participation. Nasser and Comfort Energy know how to do it right; ensure that the client doesn't want to go anywhere else for their HVAC service."

"Jorge, Angel, Ishmael, and George were fantastic. Jorge was honest and straight in the initial conversations. He gave me multiple options for systems and their functionality. When I made my selection I was given a very fair price for the work that was to be done. He was very helpful in acquiring good financing that bested my Credit Union and Bank. The work was done quickly with great attention to the fine details. I now have an efficient and functional HVAC unit. If you need repairs or a replacement HVAC system you could not do better than selecting Elite Heating and Air for your job. I'm telling all my friends that if they need any work done - "I've got a guy"..."

"Air Sharks are very professional and I think they did a good job on installing HP HVAC in our property."

"Came quickly and fixed my AC"

"Rittinger responded quickly. Alan, the tradesman they sent over was professional and quick. I hired them to install a clothes dryer vent and to open up a vent in my garage for the hot water heater. The work was high quality and installation was clean."

"I highly recommend Aire Serv of Campbell & Saratoga to anyone in need of HVAC services. Alton helped me find the right system that works for our home within my budget. Alton was knowledgeable and truly explained the different options & HVAC available that would fit for our home. Alton answered all my questions with patience and expertise. The installation crew (Rene & Julio) were on time and explained the complete removal our old system and installation of the new HVAC. They treated my home with respect, cleaned up thoroughly after the job. I like their attention to detail and commitment to doing the job right the first time. Thank you for making our home energy efficient. I'm happy with the results."

"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."
