As a local, family-owned business, Eanes takes great pride in providing trusted advice and straight-talk service on HVAC installation, repair, and maintenance for both commercial and residential applications. Additional phones - (336) 727-0120, (336) 475-8715, (336) 993-6819.(336) 287-0083. Award winning. Additional contact names - Karen Eanes, Angie Eanes.

"The “Comfort Specialist”, aka highly trained salesman, Jared Reeves was very professional and informative. He even came to my house on a Sunday to quote a new AC/furnace system, and he answered several texts with additional questions I had before signing the quote into a contract. The contract laid out, in very clear terms, what equipment would be installed and the labor involved. Unfortunately, that is where Jared’s communication stopped, despite his (and Eanes’) promise to make anything that wasn’t done correctly on the install or the equipment, made right. The day of install started early at 8am and ran long to 9:30pm. I was home the entire day, and I checked in several times to see how the progress was going. The installers were great, but I did have to question (and convince) them to replace the drain pan when they informed me they were not going to put in a new one. A new drain pan was included on the signed quote/contract, as the original was rusted in several spots and clearly needed to be replaced. After convincing them to do that, I noticed that the new return plenum and furnace drop which was included on the signed contract was not being done. When I questioned that, I was told that it was not included on the punch order. Jared (the salesman) and I specifically discussed the new return and plenum during his visit, as the inside of the original return/drop was quite dirty and dusty, naturally and perhaps the M-word (moldy). I did not feel the installers cut corners, but the new return and drop box promised by Jared and included in the contact were a hard “no, that wasn’t part of the plan” from the installers. I sent Jared a text immediately to inform him, but I did not ever hear back. The sale was done, and so it seems was he (despite sitting in my dining room with his sales pitch, promising that anything not done right would be made so, on his dollar if needed). I emailed Jared and Eanes Customer Service several times over the next week, and I got zero reply. I asked for a refund of the cost of material/labor on the return/drop that was in the contract and not fulfilled. Updated as of 7/30/2024 All issues have been resolved."

I'm a licensed plumber in the triad area, with 15 years of experience in new construction residential and commercial, remodel and service

"Eduardo contacted me directly. He was able to suggest a possible solution to my problem over the phone and give me a fair quote. Other companies wanted a service fee just to come out and one was double because it’s a weekend. My leaking toilet was repaired within the hour. Eduardo was respectful and professional. I will call him again for my next plumbing concern."

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
