"We had an off and on issue with the furnace for 10 days. Contacted another local company and their Technician went for the old keep switching out parts until something works. Bottom line Holtzople sent out Jacob King, he called professionally 15 mins prior to arrival, got into the furnace and within 5 mins had identified that the issue was in the cleanliness of the furnace. Jacob gave solid advice and performed at the highest professional level. Thank you Holtzople for your quick response, and for sending out Jacob, we will be requesting him in the future!"

"I signed up to have one of my HVAC's covered by Tim Kyle. I used the electrical service for over 20 years and the service is exemplary. This is the first time I used the HVAC service. I was impressed. It was a great job performed by a knowledgeable, pleasant tech who was available to answer any questions I had. Most important the HVAC was up and running before the 100 degree days to come later this week. Thanks guys"

"The technician was extremely thorough. Replace the thermostat batteries and furnace filter (I provided the parts), checked for any carbon monoxide leaks, checked the condition of furnace components, and found some bare wires that he taped up."

"The process was easy and the service top notch from the estimate with the sales rep to scheduling and the install. Ill recommend them to anyone who needs heating and air services."

"We're very satisfied with Supreme Air overall.  They put in what a quality system and took care of the little details, so some of the inspectors and others commented on it looking well set up.  More importantly, the geothermal heat and A/C has been working well for us, as has the heat pump water heater they installed.  There were a couple problems that came up, but Supreme was very responsive and handled everything to our satisfaction.  
We did a typical vertical well and had a split system so that we could keep our oil furnace as backup.  Supreme was good about answering questions to make sure we understood the process.
I took away one letter for punctuality because it was sometimes unclear when someone would show up for an appointment, but I would say this is understandable for the business (e.g. drillers might not know exactly how long the previous job will take). Overall, the system was completed faster than we expected, so that was a bonus.  I recommend both geothermal systems and Supreme Air."

"During the initial service visit, the representative (Xavier) gave a detailed explanation of the condition of the HVAC system and the repair options. I hired JDL and two days later they arrived first thing in the morning to install a new system (furnace and A/C). The quality of their work and products recommended are excellent. I highly recommend their services."

"I had a high efficacy heat pump system installed by ARS 11/2 ago. I am used to gas furnace so understanding how heat pump works is an education. The mechanic was very patient in explaining how it works and what to look for if there is an issue. Of course this cold season a got an high unexpected bill from the electric company and was baffled because of the amount I spent on this high efficiency unit. They came out looked at and found no issue. They explained this was a very unusual cold season and the unit performed accordingly for sub freezing condition. They did leave a card and said if I see anytjing that look unusual please give them a call asap. The mechanic was very knowledgeable."

"Had a full HVAC system installed including all new ductwork. Maurice and Tanner and Bob were super professional and very informative. Went above and beyond what was expected always stopping what they were doing to answer any questions we had. Jason Bowen was extremely polite and professional explained the whole system we were going to get and didn't try at all to upsell equipment, and didn't pressure us at all for the sale. W At your Service heating and cooling will be our go to for anything we ever need done!!!"

"Changed the brand of heat pump to be installed 24 hours before installation with no prior notice."

"I called Carroll Mechanical for an estimate on a new high efficiency heat pump system. I met with a member of their team that clearly explained everything and helped to design a solution that worked for my family at a fair price. The install team arrived on time, they were very polished, and did a technically excellent job. The system is working really well and the whole family is comfortable! Couldn’t have asked for more - I’ll be using Carroll Mechanical as my go to HVAC contractor from here on out."
