The technician was able to identify and correct my issue. What i liked the most was the detail he exemplified when locating the vent even when it made his job harder. Wonderful experience. Service: HVAC duct & vent cleaning

2022, April: The gentleman who came today was just as professional and congenial as others who have come here before him from Weathermakers. When I bought my home in 2014, Weathermakers had a service contract with former owner (prepaid) which they honored for me as new owner. They have continued to service my heat/air conditioning equipment, replaced the unit when that was needed a few years ago, and continue to service the unit every six months.

I love that they tell me what is needed and ask if it's ok to proceed. I LOVE that they blow out/clean out the algae that grows in the outside drain hose in spite of my best efforts to keep the line flushed out. Johnny is pleasant, professional, and good at what he does.

I've been with Weathermakers for almost 3 years. They are always reliable with their scheduling and with their work. My latest service today was done by Johnny Howard, an excellent and pleasant technician. He diagnosed the need for a new capacitor during his last visit and installed one today, along with a Rene - Halo and a UV BLUE TUBE. This house has never had better quality air. Another service recommendation was to change the vent pipe from the drip Pan to a one inch diameter from the previous 3/4 inch. This was done a year ago. It was not expensive yet made a huge difference in the efficiency of the drip Pan drainage. Always a on time! Great company to work with.

Johnny was a hard worker who came on the weekend and on time as promised. He checked out everything. Explained the problems and made sure everything was working before he left. Very friendly and professional. His work was neat. Everything cleaned up when he left. Thank you for sending him. I highly recommend weathermakers and Johnny. And $129 service call on weekend for emergency service is very very reasonable. 5 ************Part 2************* A/C was done.

I called weathermakers on Friday and they sent Anthony K out that day. He was great tryed to find an easy solution but He recommended a new unit which was perfect since the weather is getting hot. Had Damian call me before he left to discuss price. We agreed and they were out on Monday to install. Anthony T was here on time. He was professional, friendly, very neat. Looks like he cleaned my garage! Love that. There were a lot of follow up calls from Damian and Crystal. I highly recommed this company.

Weathermakers put simply is fantastic! I purchased my house three years ago, and their sticker was on my unit, so I took a chance. Their service is prompt, thorough, and done right every time. I had to replace my central AC and not only were they very accommodating, their pricing is extremely competitive. They came in and did the end-to-end install in 6 hours. Their install technicians were very courteous and did not mind me asking questions. The installed unit was done with extreme care, and the attention to detail was impeccable. We are very satisfied with our new AC. I would recommend Weathermakers to anyone!!
