"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

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.
