1992 years of experience

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"

Install Boiler questions, answered by experts

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

No, professional installation ensures proper venting, safety, and efficiency.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.
