"Part of the cleaners left things undone, have to call and get them to come back to finish. Otherwise, great work on restoration after a fire. They try to get it right and I would use them for the complete project."

"Nathan and his crew were able to accommodate repair and replacement on my water heater and dishwasher plumbing prep. I had a very tight window of time to get this done and they went out of their way to get the jobs done! One of the best service companies I have done business with in the last 50 years! I would highly recommend them to anyone who needs a job done and at a reasonable price, Thank you again Nathan!"

"Great experience with Flame Tech. George was knowledgeable and responsive. He provided an accurate estimate over email based on a number of photos and a few phone conversations which streamlined the bid process considerably. They replaced my AC in a few hours for a fair price and educated me on other safety considerations related to my furnace. He also helped me diagnose a rattle in my air ducts that would have given me fits. Good price, know-how, and customer service, I would use Flame Tech again."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Once the electrical box was opened and assessed it was apparent that the electrical box was pulled away from the house wall by the ground settling. Much of the wood frame behind the box had experienced water damage requiring long screws to seek enough wood meat to pull the box back to the brick wall. A vertical slip sleeve pipe was installed to adjust for the horizontal piping in the ground settling. The owner agreed to add foam, calking to help seal the wall box to the house wall and add a sloped top cover and sides to add additional protection from future heavy rain. This was an original construction land settling issue that is not uncommon."

Heating and Air Conditioning FAQs, answered by experts

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

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.

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.
