Josh was SO refreshing after getting an initial quote from another company that used overwhelming high-pressure sales tactics. He was awesome to work with, super responsive, stayed true to his word and very respectful. I reached out to Wagner Plumbing & Heating to replace an old furnace and AC unit. Josh was able to inspect my unit the same day and schedule the installation. Josh and his team were very attentive, exact and their install is a work of art. I could not be happier. If you need ace work done, I would call the folks at Wagner Plumbing & Heating.

We have used Wagner for heating and air conditioning repairs in the past. This summer we had to replace everything. They were prompt, thorough, and fully professional. This was a jolt to our budget and lives but Wagner did it extraordinarily well. I will continue to use and refer folks to them in the future.

I purchased a 5 ton Carrier heat pump to replace my aging Coleman 5 ton unit. While the Coleman unit never once broke down in the 15 years it was in service and the Carrier unit has went down twice now; the crew at Scott Wagner's has kept their word on the 10 year warranty so far and have fixed the unit at no cost to me. Their people are respectful, knowledgeable, and prompt. Maybe in another 5-6 years I will "upgrade" this unit. This is a good company, and the saying is true, "You get what you pay for"

Great customer service. My furnace was going to quit completely in sub zero temperatures, they installed a new furnace in less than 24 hours. Ben and Nick did a great job. I would definitely recommend this company to anyone needing HVAC service.

On time in arrival, friendly, did not give up and called for assistance, very informative in letting us know what went wrong and what was done to correct it. Recommendation were made in possibly considering in a new furnace and gave us an ETA and time it would take along with providing quotes I'm glad to look at there reviews and ratings it's no wonder I would highly recommend there business. Credit card accepted on sight - convenient

Have used several times with excellent results. Punctual, polite and professional. One concern from our last appointment (1/3/20) that I expressed to the office is that labor is quoted at $62/hour. However that is per technician so our 2 person crew -- great guys -- had labor billed at $124 per hour. This was not explained when appointment was scheduled and I feel should have been. However, as I stated, good service.
