"The technician showed up as scheduled. I thought I was hiring a "local" contractor but he said he had driven 2 hours to arrive to my job site. The work was done satisfactorily for what could be seen as inspecting all the duct work was not practical."

"The technician, Steve, called me 25 minutes prior to his arrival. He was extremely knowledgeable about my gas fireplace. He vacuumed all areas. He informed me of the condition of the components. I was prepared to ask him a handful of questions that he was able to answer. My fireplace works very well and I strongly recommend using the Chimney Experts."

Hello, I’m someone who believes in working hard, treating people with kindness, and always doing my best in everything I take on.\n\nStarting this business has been a dream of mine because I wanted to build something I could be proud of while helping others. I know life gets busy, and sometimes having one less thing to worry about can make all the difference. That’s why I’m committed to showing up with a positive attitude, being dependable, and paying attention to the little details that matter.\n\nWhen I’m not working, I enjoy spending time with my family and friends, making memories, and appreciating the simple things in life. Those values—honesty, respect, and genuine care—are the same ones I bring into my business every day.\n\nI’m so grateful for every customer who trusts me with their home or business. My goal isn’t just to provide a service—it’s to build relationships based on trust, reliability, and care. I look forward to meeting you and becoming someone you can count on.

"Bruno arrived early and gave me a full explanation of what he was going to do and the estimated time it would take. He was courteous and professional. He showed me before and after pictures of the air ducts. The company was very easy to deal with and I would certainly do business with them again"

"It ended up in a $500 deal.  They ended up finding mold in the air return so they ended up doing mold remediation and then they found more and I told them to just go ahead and do what needs to be done.  They seemed like they tried to up sell me a little bit. "

Air Conditioning questions, answered by experts

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
