"Blake did a wonderful job. He was so polite and respectful. He asked "when do you want them", I said "yesterday". He then ran to Home Depot to get the taller toilets I wanted. He also gave me some pointers on another matter. Thumbs up!!"

"I am VERY disappointed in my experience, even though it started out positively. Justin, the sales rep, was very helpful and I paid my deposit right after Christmas. However the customer service since it was installed has been less than optimal. The system has now shut down 3 times. I paid almost $12K for it. Este's says that the manufacturer has to send someone out to upgrade the computer. No one can tell me when that will be. Unacceptable."

"We had a full HVAC system replacement for both floors of our home, and we are truly grateful for the service we received from Weather Masters. From the beginning, the owner was understanding of our situation and worked with us on the pricing in a way that no other company was willing to do. He adjusted the cost significantly — almost as if we were paying cash — which meant so much to our family during a stressful time. The installation was done professionally and efficiently, and the team was respectful and organized throughout the entire process. It’s rare to find a company that combines professionalism with genuine care for their customers. We truly appreciate Weather Masters and highly recommend them. Thank you again for helping our family."

"Excellent HVAC service! They came out on time, thoroughly cleaned and serviced my unit, and communicated clearly every step of the way. What started as a one-time service turned into finding my new HVAC guys. Absolutely no sales pressure. Highly recommend."

"They found nothing wrong with it and just changed the filter. They responded quickly, was very respectful, and just wanted to make sure everything was okay. I can't rate them high enough and I would highly recommend them. I would definitely hire them again."

"Excellent company full of good and honest people! Twice my AC has went out and they have been there and had the problem resolved within hours. Best customer service and prices around! I would highly recommend this company to anyone and you won’t be disappointed!"
