Use ANYONE but these guys. Firstly, they didn't do the cleaning correctly (their words) and spread…read morea thick layer of dust and whatever else was in the ducts all across my house (see pics for the bigger pieces, but a fine dust was all over everything). It was so bad i walked into a room and there was a haze in the air. To clarify, what they were supposed to do was close off the vents with plastic (i made the suggestion and their manager confirmed they were supposed to do that) I spent 2 days cleaning up after them to get the house somewhat clean. All they did was have someone vacuum for 15 minutes around the vents, he was outraged that the previous techs left the house in a state like that. To add insult to injury, due to their driver's continued negligence they damaged a drain in my driveway and the city's culvert. They have admitted fault in writing but still refuse to pay for all the damages and refuses to give their insurance information. (See damage in the pictures). You can see the grate is bent, it was attempted to be bent back into place by the technician before I could get a picture, but it was bent at a 90 degree angle initially before the attempt to hide it. As well there are broken tabs in the channel itself, as well as the city's culvert completely cracked. (I provided day of and current picture due to their claims the culvert looks different now so they won't fix it.) Be warned if they do business for you that as soon as they do something wrong, or break your property you will be left having to fight them to get the damages taken care of. All pictures referenced can be seen on my Google review. Update: in regards to the company's response. I did say they sent a tech out that day to vacuum for a few minutes. They did come out to do the cleaning again after I explicitly told them It wasn't done right and that I had doubts it was effective because I was never given pics of the completed state or the coils being cleaned. As far as good faith, I have emails stating the company's attempts to not pay, first they tried to say they won't pay for older driveways (twice in fact), this driveway is 2 years old. When that didn't work they also ignored three established contractors opinions for a guy they labeled (again in writing) as "their" concrete guy, who's business has been running about a year with minimal work to show on their website. This single contractor was the only one to say a far cheaper repair would work. So, in good faith I agreed so long as they guaranteed the work and if it wasn't sufficient they pay for the proper repair as well as any additional damages the improper repair might cause. (If it worked great, if it keeps popping out and causing damage to my vehicle because the lower part is damaged, then they rightfully pay for those damages as well) As well as repair the culvert, as discussed with that same contractor. They refused by saying the culvert "looks different" so they won't pay for repairs. As for the insurance. I explicitly asked the manager for the insurance information and the owner told him not to give it. If you truly are wanting to act in good faith then feel free to call today with your insurance information. I have bent over backwards to help this company save money on this repair... i could have stopped when the first few contractors gave me quotes $1000 higher. I could have just gotten my money back when they failed to actually clean anything and cause me substantial work and allergic reactions, I could have stopped at the repair quotes that wanted to completely cut off access to my house that would have cost them a week of hotel fees... i am the only one working in good faith here.

Chris is very informative and goes above and beyond to assure my family is safe and comfortable…read more Our heat went out on a very cold December night. I dreaded making a call to any company, knowing the expense that we would face for an "after hours" service call. I avoided the BIG names and simply scrolled through until I came across Air & Heat Full Service. The ad said open 24 hours but me being pessimistic thinking yea right i reluctantly made the call at 11pm. Chris answered, to my surprise and my first concern was pricing. Mr. Overbay, Chris, explained he did flat rate billing and no matter if he showed at 9am or 3am his service call price would be the same. Me dreading the next answer I had to ask...and how much is the service call? To my disbelief the answer was more than reasonable. If I remember correctly the cost was around $70 for a late night and no heat for the kiddos I was in. Chris arrived at almost 12 introduced himself and asked to be shown to the problemed beast. He returned to me within 15 min with a diagnosis. The igniter on our 18 year old gas furnace had run a ground. He explained he could resolve the issue that night. Me being me and frugal as I maybe asked how much and how long this would take. Chris gave me a price of $110 plus the service call bringing the bill too under $200 total out the door. Me being me and not sold this ignitor was or would be the only issue, I voiced my concern. Chris what if it's something else wrong with it? Chris assured me this was the issue and if it were anything other than what he said that that would become his issue for misdiagnosing the furnace. He walked to his van returned went right to work and to my surprise had the heat restored and working in less than 20 minutes. I received my invoice and as Chris had stated no surprises no hidden charges and heat fixed for less than $200. After telling others this same headache I was told if I called one of those BIG named companies that I would have paid over that for the "after hours" service call alone. I appreciate Chris's honesty prompt service and knowledge of the trade. Air & Heat Full Service has a customer for life and many pending referrals to come. My worries are over and I know this company surely has the best interest of the customer. Many thanks to Chris and Air & Heat Full Service.

No explanation on invoice of why he doubled the price. If I could give ZERO STARS I would.

I took quotes from several local companies and waited a week for people to respond to my requests then to receive unbelievably insane, completely out of the question, Incredible, kings ransom, massive amounts of money some of these crooks wanted to do a basic charge on my unit. One company quoted me $900 to charge my unit and blamed the price on the cost of refrigerant. Borderline criminal. But, the Powell Brothers show up on time with a more than fair in fact, generous quote. Not only did they fix my unit, but they gained my admiration and friendship. This is what the Powell Brothers bring to our community. The national chains are going to hijack your bank account for their shareholders. These fellas work hard and do great work at a more than fair price. They should be your first and only consideration for heat and air. They are mine.

By the time the tech got to our house on Monday he stated that since the temp had dropped below 70deg that he couldn't properly diagnose the problem with our AC.

Nice people to work with but the last two times at the house completely misdiagnosed a "problem" I had with my heat pump. Got a second opinion and their analysis was not accurate. Saved me a lot of money having someone else look at it. Had them out one more time and was charged an exorbitant amount for what amount to 15 minutes of work. Upon inspection in the attic is was not cleaned up as they said it would be. In summary, nice people, check their work, if something seems more expensive than it should be, get a second opinion. Be suspicious of "problems" that need to be addressed.

I hired Engert to install a water pressure pump, a simple job that one man could easily accomplish…read more I called Engert to get a ballpark figure on installation, and was told rates were $65 an hour, and "it shouldn't take more than an hour." Engert sent out two men to assess the job, and the two returned later to install it, taking 1 hour. They never gave me an estimate, so I was shocked to receive a bill for $270 in labor costs. I was charged for both visits including drive time, never got an accurate estimate, and had to pay two technicians. I call that bill padding. I contacted Engert on their web site to complain of price gouging. They never responded.
