Posted on Google Zac MoncriefTrustindex verifies that the original source of the review is Google. Quick response to initial inquiry, very reasonable, great work! We reached out on a Friday afternoon, and within minutes received a response. The digonstic price was one of the best we received (but TBH, very comparable with others) We chose Big H&A because of their good ratings and speedy response. They gave us 2 windows for the following day and we locked them in. They shared they'd give us approximately 30 min warning before they would arrive. Our window was 10-noon and at 10:02 we received a text stating he was on his way. He showed up 25 min later and was super nice and professional. He immediately put on shoe covers and came in to troubleshoot. Along the way he shared what he was doing, showed any discoveries he found, and was able to fix this issue. He was great ! He didn't mind all my questions and was happy to share what knowledge he had to help me out for further upkeep. Super kind, and very clean, too. Made sure the space was almost better than when he arrived! 100% recommendation from me! Thanks again!Posted on Google Bill WetterTrustindex verifies that the original source of the review is Google. This is along overdue review for Art and his team. They always provide excellent service, starting with repairs to my 30+year old hvac and then when i need to replace it. Art was very easy to talk to and answered any/all questions I had about why a repair was need and why we should replace the existing unit. This is the company to call for any HVAC or appliance repairs!!Posted on Google Jeff BenjaminTrustindex verifies that the original source of the review is Google. George was terrific and solved our problem lickety-split.Posted on Google Meelosh or MilosovichTrustindex verifies that the original source of the review is Google. We had an issue with our oven. Upon making our initial reservation Aziz stayed in regular contact even when their technician couldn't make it out due to the crazy storm and holiday crunch. Aziz staying in constant contact and promptly rescheduling us for the first available tech appointment the following day after Christmas was a relief and super helpful. Technician was in and out and quickly replaced the bad ignitor on our gas oven.Posted on Google Jacinda MitchellTrustindex verifies that the original source of the review is Google. So pleased! The technician was on time, knowledgeable and easy to talk to! Explained what he was doing wasn't condescending. Will definitely be calling them again for my appliance needs!Posted on Google Pooja ChaudharyTrustindex verifies that the original source of the review is Google. Excellent and reliable service The dishwasher technician did a great job from start to finish. He arrived on time, clearly explained the issue, and fixed the problem efficiently. His work was neat, professional, and done with care. I really appreciated his honest advice .
Posted on Yelp Theresa G.Verified Truly exceeded my expectations! I noticed my AC was on but not cooling (the thermostat wasn't getting under 76!) so I decided to have a tech come out and take a look at it. I found Big H&A via Yelp and chose them based on the good reviews. I'm so glad I did! They answered the phone immediately and said someone could be there within two hours. George showed up promptly and quickly diagnosed the issue and fixed it for a fair price. He was communicative, fast, and truly a lifesaver in this heat! I would 100% use Big H&A again in the future!Posted on Yelp Dee Dee R.Verified I called Big H and A, because my air conditioner went out. I had previously had called other companies, but the other companies turned out to be unreliable. Art arrived in a timely manor, diagnosed the situation, and repaired my air conditioner. Art was very patient when I asked a lot of questions. Great job, Art! Thank you for everything! I will refer Big H and A to everyone!Posted on Yelp Henry S.Verified Had Art come and service my AC unit and get it ready for the summer! He was on time, efficient, and able to troubleshoot the problems and explain what the repairs would be needed! Thank you Art for your professionalism!Posted on Yelp Shay R.Verified Quick response, showed up on time, and completed the job quickly and without any fuss. Really appreciate that our tech knew what he was doing, was straightforward in explaining the issue, and was extremely efficient. We would definitely use them again!Posted on Yelp Spencer M.Verified Big H & A is the best! Have had 2 different AC issues this year and George fixed them up both times very quickly - they were out here in under 24 hours both times. Great service, really helpful advice and great value. Thank you Big H & A and George!Posted on Yelp Chris T.Verified Finally, an HONEST appliance repair company. Art was my technician. My older Subzero frig seemed to be running hot around the vents. Another company had quoted me $3200 for a new freezer compressor. Art said that wasn't necessary. He performed a cleaning of the coiling springs and took the bottom vent cover off to let the refrigerator breathe in the future. Instead of spending $3200 I spent $185. He also serviced my older HVAC unit, a more obscure water source heat pump model that not alot of people service. Two other companies told me the unit needed to be replaced at a cost of anywhere from $5000 to 12,000. I told Art a third company had already done a very expensive deep clean. He said it was good that I did the cleaning but that it only needed to be done every five years. He replaced some of the freon for $130 and colder air was blowing thru my vents in no time. All in all, this company saved me a boatload of money and I appreciate it.Posted on Yelp Rick T.Verified George from Big H & A performed a tune up on my older A/C system. Very fast service and quality work!Posted on Yelp Claudia K.Verified Big H&A was quick to respond to my request and very communicative throughout the process. The technician George was knowledgeable, efficient, and thorough with his inspection and repair of our HVAC. Highly recommend and would use this company again.Posted on Yelp TinaVerified Excellent service by George. Came within 1 hour of me calling and fixed our air conditioner in that one visit. A+++Posted on Yelp Sung C.Verified George fixed my mini split hvac system. He was very professional and on time. Very happy with the results.
