WeatherWise was EXCELLENT! Our furnace stopped working unexpectedly. They responded by coming out the same day. Frank (the owner and technician) was upfront about likely needing a replacement but he would try to replace a part to get us heat in the mean-time. After it was determined that our furnace was condemn-able for several reasons Frank discussed new furnace options with us. He was upfront with cost options, benefits of different furnaces, etc.

Called this company to have them check out the furnace in a house we recently bought. Because of the age of the house, I was worried we’d need repairs or worst case, have to replace furnace. Technician showed up on time, and was very professional. He spent time cleaning and inspecting our unit and when finished, he said everything was in good working order - nothing more was needed. WOW!!! An honest company! So refreshing! THANK YOU Weather Wise!!!! You get an A+ from us!

Great experience with them. Extremely prompt and polite. Frank came over exactly when he said he would and answered all questions. He took the time to go through everything and we talked about what I actually needed long term vs up selling to something I wouldn’t see the ROI on. Gave me multiple options to look at and the price was much less than we budgeted for because he didn’t oversell Installation was very easy and they cleaned everything. They were able to come out the same week and Frank stopped by again to check the job.

Frank and Weatherwise have been taking care of our HVAC needs for many years, including a new AC unit installed this afternoon. Frank went above and beyond to find a remedy for the old unit before ordering the new one. Jeff and Brandon completed today's new install in a very timely manner, and were as happy as I was to get the windows shut and the house cooled down. I value quality, character, and integrity, which is why Frank and Weatherwise is and always will be our go-to.

When I decided to replace our ancient furnace and AC, I relied on Google reviews to locate highly rated companies near me and found three whom I contacted for a quote. WeatherWise stood out as the folks with the greatest expertise, the best customer service, and the most competitive quote. They arrived at exactly the time they promised and installed everything within the time frame they had estimated. They did a highly professional job, cutting no corners and keeping me informed through every step of the process. They left our home as clean as it was when they began. When all was complete, they walked us through our brand new system to make sure we had all the information I'll need in the future. Since then, I've emailed a few questions to them; and they responded within hours with the exactly answers I needed.

To say it was a pleasure working with Frank and Weatherwise would be a major understatement. I found that everyone at the company was professional, polite, and caring. Frank went above and beyond to ensure that I was happy with the service. Do yourself a favor and give this company a call. It'll save a lot of time/hassle and you'll be thrilled with the experience.

We had Frank from WeaterWise install our new water heater three years ago. He did such a great job that we chose WeatherWise to install our new central air, furnace and humidifier in April of 2019. He and Kevin did a great job! Everything went perfectly! We would highly recommend WeatherWise!

Weatherwise was at my home to help me when my heat wasn’t working. All that was wrong was my old thermostat was faulty. They put on a new thermostat and now I have heat again. They were very friendly and professional! I definitely recommend them!

Weatherwise is amazing. I can tell you that these guys really know what they are doing, they are priced very fair, and treat you like friends and family. Of all the service companies I have dealt with in my time they are by far the best. Frank, on behalf of my family and my self we thank you from the bottom of our hearts for your service. A new furnace 2 days before -25 degree temps is a huge relief. Thanks again and we will see you next fall for service.

My furnace went out and after we already had weather wise out to fix the furnace in October they were able to get to my house right away. Mike one of the repair guys was amazing explained everything and was never pushy on what we needed. He was able to get me a new furnace installed the next day. They worked with me and were nothing but amazing. I will not let another company come into my house to fix any issues I have!! Thank you guys you are amazing!!!

Frank and crew are true professionals. They arrived promptly and proceeded to replace both my ac and furnace. They explained everything about my new system and new thermostat. They even changed the filter placement to make it easier to replace. They are a wonderful family run company that I highly recommend.

I had a fantastic experience with WeatherWise! I was inbetween three different companies, and chose WeatherWise because they “sized” the equipment correctly to my home’s square footage/specifications; they didn’t just try to sell me the biggest A/C unit (which the other two potential estimates did). The crew was friendly, cleaned up after they were done, acted professional & explained how everything worked to my wife & I. If you’re on the fence, choose WeatherWise; I promise you won’t regret it.

Frank is very professional, and made certain I was completely satisfied. He answered all my questions, and made more than one personal visit to be certain I understood the furnace and a/c details, installation procedure, and cost. I recommend contacting Frank at WeatherWise Heating and Cooling before you make your final decision.
