We are full-service heating and air conditioning company that provides residential and light commercial service, installation and maintenance. We truly believe that if we focus on helping people and treat others with respect, our customer’s experience shall be an amazing one.

"poor customer service. service manager insulted me, called me derogatory names while defaming my character. when all I was looking for was for someone to right a wrong. I was actually looking forward to them coming to look at my furnace and was hoping to find a trusted company but was given the complete opposite of what I expected. first no one called me with an update, I had to call, then no one showed by 5pm after I waited patiently all day during their 8-5 window. finally at 5:10 i reached out again only to be met with an after hours line that couldn't help me at all. once I spoke to SM, he insulted me, called me derogatory names and defamed my character all because I was understandably upset for being "brushed off" by everyone I had come into contact the entire day and given excuse after excuse with no solution that was going to benefit me. Customer service and professionalism are lacking 100%"

FAQs for tankless water heater installation projects in Olney, MD

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
