"Very pleased with this contractor and the cost and quality of their work. Upgraded my panel to 200 Amp service, split an overloaded circuit, and ran a line set for an HVAC project. Max and his team are real pros. The cost estimate was fair and accurate. After initial review of the project, we made a few changes on job day, and these were accomplished with zero problems. Their coordination with the electric co-op was also flawless and the job was accomplished on time and within the cost estimate. They even gave me a $100 credit for the removed 100 Amp panel. I plan to hire them again to wire an existing out building on my property. If you need electrical work, call them!"

"They did a wonderful job from beginning to end - were mindful of our budget and did not recommend more than we needed. They also offered a great financing option. The HVAC contractor arrived as scheduled, completed the job quickly, and cleaned up completely. The furnace has been in operation now for over a month and we have had no problems."

*** I have recently added the Nashville area to my service coverage. Since I can do most of my services remotely with you over the phone, I am hoping to eventually open up to larger markets and help people from having to take their computer in to get it fixed, if it has internet access, I can usually fix it over the Internet. Just trying to do more to help my Angies List customers!!******** I am a sole proprietor that works out of my home. I am my only employee, but I have over 20 years experience fixing computers, and providing superior customer service. I work on a flat rate service, and don't charge by the hour because I feel it's important to educate the customer on what the issue is/was, and how to avoid it in the future. I feel that local service companies (my competition) have been overcharging customers for years. I offer a first time customer discount of 10% but I will offer 15% off for first time customers referred by Angies List. I've lived in the Huntsville area most all my life, so I know the area very well. I will never use a subcontractor as I am very picky about making sure that if my name and company is associated with something, it will be the best experience my customer has ever had, and using sub contractors won't ensure that, so I prefer to do all the work myself. Lastly, I should point out that I am a former offensive lineman for the University of Southern Mississippi and was Brett Favre's center his freshman year at Southern. I went on to play for Tom Landry in his last year, but gave up pro football early on to pursue my passion of fixing computers. If I didn't have bills to pay, I would do this for free because I love it! If you have a computer problem, I promise you that you couldn't find a better technician that will care about you as a customer, and not about the bottom line. I am always available, but don't always answer my phone, but if you leave a message, I promise to back with you as soon as possible...and figure out how to get your issue resolved in a quick, efficient and economical manner. Thanks so much for reading my ad, and I look forward to working for you!

Heating and Air Conditioning FAQs, answered by experts

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.
