"Great installers precessional and respectful"

"The whole house could hear the vibration when our two year old Tran xv20i heat pump was at 67% work load. It seems the issue started from day one it was installed. Tried to reach out the installer but they went under. In June, I called McCrea. Mark Dzbynski came over, carefully checked everything and then concluded that refrigerant was not charged to the correct capacity. He explained that our system line is longer than usually and additional refrigerant is needed to compensate the length. He carefully calculated and addded the correct amount based on the temperate & length. From June and Oct, the vigration never came back. No one can tell when the system is on because it works so quietly. I really appraicate the work done by Mark and his work ethinics. Very pleased!"

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"I have an annual contract with R.W. Harrell's Pump Service to clean and service the heating and A/C systems at my home. Their employees and always prompt, courteous and professional and ALWAYS do an excellent job with cleaning up before they leave. Their prices are reasonable and I like dealing with locally owned companies as opposed to the nationally owned companies. I would highly recommend R.W. Harrell to all of my friends and relatives for their HVAC needs.

"They came and inspected the sump pump. They recommended for it to be replaced. I was okay with it so they replaced it. They completed within half an hour. We then discussed the bill. They agreed to take off $50 because they have an Angie's List coupon that offers $50 off. There was also a coupon for $250 off a system installation for Angie's List members. I told them of this and they said it would only apply for HVAC units and I said to them that they are more than HVAC company, they provide more services than HVAC. They did not specify that its only for HVAC. The technician agreed and said that they're going to have to change that within our website. This was extremely misleading and felt like a bait and switch."

"When my desk top computer failed I called Mr Ferrell. His response time was excellent; arriving at my home the same day I called.
He called me back that evening to update me on what he found. He replaced the power supply and did a virus scan and returned the computer to my home within 48 hours. I found him to be computer savy and very friendly. If we have computer issues in the future I will contact Mr Ferrell.

"Alder Cruz and his company American Air is our HVAC Company. Alder has taken care of our HVAC needs since his first visit to our home @2015. He uncovered an intermittent problem with our system that was not found by several other specialists/companies. We were spending over $300 monthly having different people trying to help us. Alders persistence and technical skills are top notch! He continues to provide us superior service. He has replaced both our heating systems. One system was switched from gas to electric. He made it so easy for us. They respectfully cleaned up any mess they made. Work is performed on time and within budget. We unhesitatingly recommend American Air / Alder Cruz for all your HVAC needs. ~Tom & Deb Canfield"

"it went out very good, i was advise to replace the fan pf the central air very soon."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."
