"Very fast and professional service! I received a text just 5–7 minutes after submitting my request on Angi. Kati explained the process and quickly scheduled an appointment. Johny arrived within an hour, inspected the old heater, and although he suspected it needed replacement, he still contacted the manufacturer to explore repair options. The repair was estimated at $300–$400, but we chose to replace the unit instead. The replacement was completed within 5 hours of the initial visit. Kati and Johny were patient and informative, walking me through payment options and explaining the differences between heater models. Overall, excellent service and quick turnaround. I wish it had been a bit more affordable, but I couldn’t get quotes from other providers without a home visit. Highly recommended!"

"From the moment I received a call from Tammy at Advanced Environment Solutions Inc. (AES), I knew I was dealing with a company that stands out from the rest. We had been shopping around for HVAC replacement quotes, and to our surprise, AES offered an over-the-phone estimate that was a staggering $7,000 less than any other quote we had received. This wasn't just a promise; it was a reality that they delivered on with professionalism and integrity. The process was seamless. After a quick confirmation visit by their technician to verify our unit size, everything was set in motion. On the day of installation, despite the sweltering heat, AES's teams worked with remarkable efficiency. One team expertly removed our old unit, and almost immediately, another arrived with the new one. The entire replacement was completed in a single day, leaving us both amazed and immensely grateful. The staff at AES were not only professional but also incredibly courteous and knowledgeable. They explained each step of the process, ensuring we understood everything. The quality of the new HVAC unit they installed surpasses any expectations we had, offering superior performance and energy efficiency. What's most puzzling and impressive is how AES manages to undercut competitors by such a significant margin while providing top-notch service and quality. This is a testament to their business model, which prioritizes customer satisfaction and ethical pricing. We highly recommend Advanced Environment Solutions Inc. to anyone in need of HVAC services. Their commitment to excellence, combined with unbeatable pricing, makes them the go-to choice. Contact AES, and like us, you'll discover why they are simply awesome!"

Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez
"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

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.
