I do a wide variety of things like changing a light switch to remodeling a bathroom. Kitchen or basements. Such as plumbing, Drywall , electrical.and Carpentry. I stand by my work 100%

"Dave was great. When tackling one job, he went overboard to perfect the job which I appreciated. He looked at all angles to make the job perfect. He was very accommodating, on time and really put us all into the jobs which were challenging. I am very happy with Dave and also his associate who was also very accommodating into making the job perfect. It was a pleasure and of course I will hire his company again. "

"First class operation all the way. Miles and Caleb were polite, personable and prompt. They had a very hard time disassembling the old boiler but were persistent and ultimately successful. They then made sure the new boiler was installed and working, even though that made for a very long day on their part. We are completely satisfied with the new boiler and their performance getting rid of the old one and installing the new one. We now have heat which is very welcome!"

Heating and Air Conditioning questions, answered by experts

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

Evaporator coils last between 10 and 15 years before they need to be replaced—as long as you stay up-to-date with routine maintenance. This is roughly the same life span as most AC units. So, if you have an older air conditioner and the evaporator coil goes out, it might be more cost-effective to replace the whole unit rather than just the coil.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.
