Fixing Water Heaters All Across the Treasure Valley

Investing in a new water heater is a significant decision for any household or business. With a multitude of options available in the market, choosing the right one can be overwhelming for some. However, by considering several key factors, you can ensure that you make an informed decision that meets your needs and budget.

    Complete Water Heater Repair – What’s Involved?

    A proper water heater repair starts with a comprehensive inspection to diagnose the root cause of the issue. Our licensed technicians will:

    • Check for leaks or corrosion on the tank or fittings
    • Test the thermostat and heating elements
    • Inspect gas valves, burners, or electrical components
    • Flush sediment buildup from the tank (if needed)
    • Examine the anode rod and pressure relief valve
    • Clean flame sensors or ignition systems in tankless units
    • Ensure proper venting and water flow

     

    Once we identify the issue, we’ll walk you through your options and provide transparent pricing before any work begins.

    Common Causes of Water Heater Problems

    Water heaters are hardworking systems, but over time, a variety of issues can arise. Some of the most common causes of water heater problems include:

    • Sediment buildup – Minerals from hard water collect at the bottom of the tank, reducing efficiency and potentially damaging the unit.
    • Heating element failure – Electric models often fail when their heating elements burn out.
    • Faulty thermostat – A broken thermostat can lead to inconsistent or no hot water.
    • Corrosion and rust – Internal corrosion can lead to leaks and premature failure.
    • Pilot light or ignition issues – Gas models may stop heating if the pilot light won’t stay lit or the ignition system fails.
    • Excessive water pressure – High pressure can stress the tank and valves, leading to leaks.
    • Scale buildup in tankless systems – Without regular maintenance, mineral deposits can clog the heat exchanger and reduce performance.

    Why Choose Gem Heating & Air Conditioning?

    Whether your water heater just started acting up or has completely stopped working, Gem Heating & Air Conditioning is your go-to partner for professional, prompt service. We’ll restore your hot water quickly and ensure your system is safe and efficient for the long haul.

    We had initially gone with our original HVAC contractor who had installed the system 9 years prior. A couple of weeks ago, they came out and fixed an AC issue and supposedly did their maintenance service on our furnace. They installed a new capacitor on the AC but said the burned out capacitor had created some other issues and the AC would not work for long. They wanted to sell us a whole new unit. A week later, the gas furnace wouldn’t kick on. We called out Gem Heating and they came out within 24 hours. They said our AC was fine and no damage was done by the burned out capacitor. They also fixed the furnace by blowing it out with a compressor. They said that should have been done as part of the routine maintenance for which we paid our prior contractor. We since learned that our prior contractor had been bought by a private equity firm. We were very happy with their installation 9 years ago, but not so much this time around. We would highly recommend Gem Heating, but recommend staying away from Ultimate.

    10/10! Gem is a local HVAC company with honest business practices. Gem Heating stood out from the start. I talked to the owner, James, to schedule a diagnostic visit for our aging A/C that was acting up. He came the same day, and was friendly, knowledgeable, and thorough. I didn't expect him to be willing to work with our old A/C unit, but he gave us multiple solutions that covered a range of costs. James did a great job educating my husband about our system, and explaining what was going on and how each solution would work. Once we made our decision, he had our A/C up and running within an hour. Gem Heating stands out as an HVAC company that is personable, thorough, and trustworthy. Highly recommend!!

    James came out very quickly for an urgent AC matter in hot summer weather. We so appreciate his professionalism and conversation about our system. He was willing to talk us through his estimate and hear our thoughts and concerns. He ended up going above and beyond. We highly recommend Gem Heating! And we love that they are truly locally owned and ran, not some big corporation that pretends to be local.

    James did a great job. He was out at our house within 2 hours of my calling in for services. Not ont did he fully explain what was wrong with our unit but showed me all the system test results. He was very professional and respectful. I would not hesitate to recommend his services to others who need good HVAC services!!

    We recently had an issue with our A/C Cooling Properly. I contacted Gem State Heating and Air Conditioning to schedule an appointment. James visited our residence and immedietely identified the issue that was causing our A/C unit to improperly cool down. Within a short time we were able to cool down our home; which is critical during the summer months. I highly recommend Gem Heating and Air Conditioning for HVAC Services.

    James came and diagnosed our water heater issue and had us fixed up in a day. Customer service and communication was above and beyond. Pricing was fair but the personal small business touch was worth every penny. He even painted and primed the wall behind the water heater which wasn’t even in the original bid. If you need anything to do with heating and air, plumbing, etc. these are the guys to call! They’re the only ones allowed to touch our mechanical now!

    These guys are personable and humble. They do exactly what they say they will do, and will not screw you over like the other HVAC companies in the valley. Other companies just want to sell you new units even though all you might need are repairs. Not this team. This team will take care of you and I trust them wholeheartedly. If I did HVAC, I'd proudly work for someone like James. 🔥

    My mini split decided it wasn’t going to blow anymore cold air due to a leak. Called Gem and they came out the same day to get me hooked up. He quickly found the issue and took care of it. Now it’s blowing nice and cold. Highly recommend Gem Heating & Air for their professional and fast service.

    Frequently Asked Questions

    On average, you can expect between 10-15 years out of your water heater if it has been maintained every few years as recommended. 

    Replacing your water heater starts with safely removing your old unit followed by installation of the new unit. Normally this process will take us a few hours on average but can fluctuate based on numerous factors. You can contact us for more details. 

    Every few years is when we recommend having your water heater serviced which includes flushing your tank of any debris, checking the heating element and other components that keep your water warm in your home all year long.

    A few reasons, but mainly because your hot water when exiting the tank has to travel through your pipes which are extra cold in Winter. By turning up the heat level on your water heater, this will increase the amount hot water available and help prevent your hot water turning cold faster.

    Yes we will, however we always recommending consulting with a professional before purchasing from a store. This will help preventing any sizing or compatibility issues which could turn into extra hassle should you have to return your water heater.

    Yes we do! All of our installations are back by our Gem Heating & Air Conditioning warranty.
