"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"

We are not a global, national franchise or a remote out of state contractor with no local ties. We are a homegrown, local minority owned company committed to customer satisfaction. Founded in 1992, our company has performed over 100,000 service calls, and have over 30 years of experience. Insured, licensed and bonded we provide perfect service delivery to every customer, every time. We are a two time "Best Of Baltimore" winner. We are an Angie's List Super Service Award Winner 2011-2020. We service Anne Arundel, Baltimore, Carroll, Cecil , Harford, Howard counties, Baltimore city and southern Pennsylvania.

"Home Systems Appliance Repair did an excellent repair on my 18 year old panel-ready 42 inch Built-In counter depth GE Profile Refrigerator. The original GE tech who looked at the leak in the freezer evaporator a year ago, told me the refrigerator was non repairable because the "vacuum pump" retrofit part it needed was no longer available. After paying his $200 visit fee for a 2 minute consultation, he offered me a discount on a new GE refrigerator to fit which had not been built yet. Fast forward to now, GE does have 42 inch built-in counter depth Monogram side-by-side for $12,000 and $2,000 of Kraftmaid panels. Home Systems Appliance Repair cost me $400 to identify and fix a broken heat transfer tab in the freezer evaporator unit. I saved $15,000 - - not bad for paying Appliance Repair for a 2 hour job. They seriously looked and found the problem. I highly recommend Manny (the tech who did the work), and Home Systems Appliance Repair. Susan"

Tankless water heater installations FAQs

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.
