"The technicians that came out were very professional and knowledgeable. They installed a complete heat pump system and did not leave until I was completely satisfied. The original thermostat that came with the system did not work, so installed a temporary thermostat and order a new one. It was installed the next day. All techs that came to my home were very professional and knowledgeable, the service was great"

"Very satisfied with responsiveness, punctuality and professionalism! Danny was able to squeeze us into Blue Star's full schedule at a time that worked for us and called before the visit for clarification about the problem, and after the visit about how things went. John called before arrival to let us know about exact timing, and was very thorough in investigating the problem and then explaining the situation. After consultation, he was able to repair our system. John also discussed what to look out for in case there are problems in the future. We have had our AC unit serviced regularly by other companies, but we will never use those other companies again. Blue Star is superior in every way! Cannot recommend highly enough. Thank you, Danny and John!!"

"Corey serviced our HVAC system. He checked for leaks and recharged our system. It is working much better now. The service was efficient and he explained our options clearly."

"Showed up late, didn't install the bathroom fan as the manufacturer recommended (pic, fan5), dented the fan grille (pic, fan1). It was installed without the supplied support rails because he claimed he couldn't get in the attic. Now sure how I got the photos, then... The vent hose was kinked in the attic and hardly any air came out of the soffit, so I had to go into the attic to correct it. That's when I took the photos. Didn't give a price up front because apparently a bath fan with bluetooth speakers isn't in whatever book they price from. Not in the book? Overcharge. Generally very unhappy with the whole experience and will be looking elsewhere in the future. Not sure how when the customer supplies EVERYTHING but a romex clamp someone can charge so much. Absolutely unacceptable. $465 to have someone dent my fan, install it incorrectly, and throw out the parts that weren't used. Like the battery to the manufacturer supplied remote and the joist supports. I'm leaving the cost of service as originally quoted because it was only lowered to $465 after I complained about being ripped off."

"Immediately established service and explained all options"

"Just started working with Markool this summer and they have been fantastic!

"Technician, Jimmy Bevens, was great; Customer Relations dept were non-responsive and the salesman acted and sounded like a used-car salesman on a lemon lot. Hard pressed to use F H Furr in the future."

"I sincerely did not have a problem with the professional service per se, the technician was professional prompt on time, and knew what he was doing. On Dec 9, 2020, it took him about 30 minutes to figure out the problem and found the unit is still under warranty. He ordered the part and told me once the part is received, I will be contacted to schedule replacement. I called the office they did not call me. They were quick in responding and replaced the part on Dec 19. Cost is my main issue. They wanted $119.95 for diagnosis fees which WILL NOT be considered a part of the final repair fees. I believe it’s not a good business not to tell the client beforehand how much you will charge as service fees, they did not. Only after they diagnosed it. After a discussion with the technician, he talked to the office and the service fee was forfeited. The part replacement cost was $403! It took less than 30 minutes, 25 to be exact, to replace. Not sure how the rate of this charge is justified. I was told about the $403 charge right after the first visit but did not have a choice at that point. With all due respect, I understand, as explained to me, they have more overhead budget more than mom and pop shops. I still believe this total repair should not have been more than $250 at the most."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."
