"I called ThermoTech Solutions and they sent out a technician within 24 hours. I was pleasantly surprised that the technician was the same gentleman I talked to over the phone so I did not have to retell what was wrong with my system. Jason my technician who is also the owner was great. He tested my system, knew exactly what was needed, and had it repaired the very same day. He did not try to sell me on upgrading my unit or a bunch of repairs I did not need. The service was fast, very reasonably priced, and I have had no issues since. Will definitely be having ThermoTech Solutions come out for all my HVAC needs in the future!"

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"David Flores.Ontario.CA. - Our sales guy Daniel was personable and informative. He was easy to get along with. I chose NRG because of the price and the customer service. We got 4 quotes from different solar companies and NRG stand out the most because they were more family oriented and also been in business for a long time. Tiffany whether it was email text or phone she immediately got back and answered all my questions to my satisfaction. Installers were professional and installed 16 panels and panel upgrade in one and half day. Robert came to my home and checked the quality of work from the techs and gave me useful tips on how to use my solar efficiently. Great guy and shows great customer service skills. I would recommend this solar company to anybody trying to get quality work done."

"We reluctantly conclude that dealing with Park Mechanical and Lennox has been an expensive mistake for us. In July 2013 we signed an “investment agreement” with Park to install a new Lennox furnace and air conditioning system in our house, to replace the old system, at a cost of over $10,000. Then we learned that the five-year Lennox warranty would be good only if we paid Park to inspect our system periodically, to certify that it has been “properly maintained.” To accomplish this we were persuaded to join a Park program called the “Shamrock Club,” under which we have been paying Park $99 a year for periodic inspections to certify that the equipment still qualifies for warranty coverage. One such inspection, in January 2016, declared the system to be correct and operational. But in May 2016, when the first hot weather arrived and we turned on the air conditioning, it did not work; there was no cooling. A Park technician found that something called the TXV valve had failed. After several hot days waiting for the replacement part, the valve was replaced and the system worked again. The repair was considered a warranty issue, and we were not charged. Similarly, on March 28, 2017, a Park technician inspected the system, found it to be functioning normally, and declared it to be “on maintenance.” At the beginning of May 2017, however, when the weather turned warm and we turned the system to “Cool,” it failed again. A Park technician found that all the refrigerant had leaked out, and refilled it pending permanent repair of the leak. On May 15 the technician returned and told us we would be charged $238 for the refrigerant and additionally for the labor to fix the leak. This time we learned that the Lennox warranty covers only the parts themselves that fail, and not the labor or the refrigerant needed due to the failure. No leak was found, and we were informed that the next step would be to inject a florescent marker dye into the refrigerant to show the leak – at an additional cost to us of $395. This failure is due to a failure in Park’s workmanship or in the Lennox equipment itself. The cost to fix it should be covered by warranty. Our disappointment with Park also includes Lennox, which offers only minimal warranty coverage for its products. Our experience may indicate why the company has so little confidence in what it sells. Our specific issues are: 1) Having to pay extra for warranty coverage on expensive new Lennox equipment. 2) The warranty does not cover labor and other costs that are likely when warranted equipment fails. 3) Our Lennox system has failed twice in the space of a year. This is not acceptable reliability. 4) Every Park inspection of our system has declared it to be operational and adequately maintained, including those immediately before the two equipment failures."

"A technician from Hawthorne Plumbing came at the appointed time and did fabulous work! The shower drains perfectly now. Other vendors were quoting me in the $250-300 range, which seemed overpriced for about 20 minutes of work. Hawthorne had a "single drain special" for about $80, which was reasonable."

"After receiving a number of estimates for the work required, Spectrum One came through right in line with our budget. Dennis was nothing short of extremely professional, always answering phone calls regardless of day or time as well as providing expert opinions. We would not hesitate to call Spectrum One again. Highly recommended!"

"It was excellent work and highly recommend for future services."
