"Made a call at 8am. Service technician arrived on time at noon and problem was solved AND fixed within a half hour. Technician was polite, kind, neat and clean but also got down to business quickly. Best part was... he had the part on his truck so there was no back and forth!"

"I currently own a rental property in Michigan. I often find it difficult to provide quality maintenance from afar, I live in Florida. When my tenant called and informed me that the furnace was not working, I immediately called Aire Serv. they have provided furnace tune ups for me in the past and have always provided top notch customer service. 
I worked with Bradley Bonniville, their furnace retail rep. He was patient and took the extra time to assist me with picking out the best furnace unit for my budget. He even took pictures of the final product and sent them to me when everything was done!
I highly recommend Aire Serv for any heating and air services. Thank you so much for the great customer service.

"One of our two 40 gallon gas water heaters went out. We requested a senior service technician to assess options for replacement: two smaller water heaters, one larger water heater, or hot water on demand. The technician was knowledgeable and gave us all the options, and we selected the single heater. They told us all the steps, let us know when the water and electricity were being turned off, and kept the house clean on a messy day. They discovered that our sump pump was malfunctioning and replaced that, too. We purchased our own kitchen faucet, and they installed it. Not an inexpensive set of repairs, but the team was very responsive and professional."

"The audit went well.  The follow-on work (water heater replacement, heat pump replacement, and caulking).
They did a pretty good job.  They did sub out the water heater and heat pump parts.  The new water heater had a heat pump unit on it too.  The water heater had an alarm that went out and was eventually replaced.
The subs did test my patience when they started late and ended even later than they said they would.  I eventually told them they had to get out at a certain time.
I took a year to write this because I wanted to back it up with cost savings info.  Unfortunately, the jury is still out on whether or not the system is paying for itself.

FAQs for water heater repair or service projects in Williamston, MI

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
