"They were clean and considerate and understood our health concerns. They removed all infected material and mold, fogged the room for airborne spores, and fixed the outside gutter problem which caused the mold. You should hire them."

I am a jack of trades independent contractor/ handyman with 10+ years experience. I am not a licensed plumber, licensed electrician, or licensed roofer. With that said it's easier to just tell you the things that I don't do. I do not do drain work, I do not replace electrical lines or panel boxes, I do not replace plumbing lines which includes water and gas, and I do not replace roofs. Aside from that I can do everything else, and have the tools to do so.

"When my HVAC unit went out I called A n 1 at 12:30am, as I have gotten home from work not too long ago. He answer and said he be right there. He came through check it all out and let us know exactly what needed to be done. He quote us too on the price if we decide to stick with him. Since he is a smaller personally owned company he didn't have financial options. So we had to think if over. Anyways I offer to give him some cash for coming out here so late and he kindly refuse, which was very kind of him. Even though it was already 2am by the time he was done checking it all out. After a few calls to other companies we realize we rather pay a hard working, honest man and help smaller local business. Also his price was unbeatable and the quote he quoted us was what we pay no hidden cost or anything. Needless to say we were highly satisfy with his work and his honesty. He was upfront with what was needed and didn't not try to sell us on anything else. Highly recommend his service! And the price was very reasonable!!!"

"Doug and his assistant (don't remember his name) were very professional. They were nice to my "scaredy" dog too. They showed me the before and after pictures of my duct work when they were done and it was the difference between night and day."

Heating and Air Conditioning FAQs, answered by experts

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

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.
