"I he was very professional and on time. I had a quote from another contractor to replace a zone valve and expansion tank that I thought was excessive. He assessed my furnace and zone valve. He found that it wasn’t wired properly and fixed the issue within minutes."

"I had an issue with my computer where it was opening lots of pop ups, ad bars, and windows with ads for games. I had tried several different programs to try to remove it with no luck. I finally decided to call North Alabama Technical Service to see if I he could help. I was expecting to set up a time for him to look at it but he connected to my computer immediately and within an hour had it fixed and running perfect again. Great service at a great price and I didn't even have to disconnect it and carry it somewhere! Would call again if I have another issue I can't resolve myself."

"i think ill be real happy with the furnace but i wont know until this winter. the contractor that did the installation for sears was absolutely great. my only problem, is when i call sears with a problem or question, they don't call me back. the service after the sale is leaving a bad taste in my mouth and i hope i dont regret using sears."

"Precision Air came out to fix a forty year old boiler system serving four units. Unfortunately, another repair company had botched a previous repair. The problem was like an onion, fix one thing, another layer appears needing service. Nonetheless, Joe, Jim and Roger went above and beyond to make sure the boiler system is in working order and fully restored to intended functionality. And, when that new problem would pop up, not from their work, they were there immediately to make sure heat worked during some bitterly cold days and nights. They did not give up on the problem or me when they could have. Now, I have a working boiler system with a 2 year guarantee. Thank you guys!!"

Air Conditioning questions, answered by experts

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

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.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
