"My heater went out in the middle of the night Saturday on the coldest day (28!). I called SeaCoast and they had David out here within 30 minutes and had it repaired in less than 30 minutes. Super nice guy, very knowledgeable and professional! I’ve been using SeaCoast since 2006 and I have never had any problems with them. Always professional, courteous, and I never have to wait long at all for an appointment. They’re the best!"

"I recently had my old water heater replaced by Luz Plumbing And Cooling and I couldnâ t be happier with the service I received. From start to finish, the entire process was seamless and professional. The initial consultation was thorough, with the technician explaining all my options and helping me choose the best water heater for my needs and budget. They were transparent about costs and provided a detailed estimate upfront, so there were no surprises later. On the day of the installation, the team arrived promptly and got to work immediately. They were courteous, respectful of my home, and took great care to minimize any disruption. The installation was completed efficiently, and they even took the time to explain how the new system worked, ensuring I felt comfortable with its operation. What truly impressed me was their attention to detail. They not only removed the old unit without making a mess but also cleaned up thoroughly after the installation. Additionally, they checked all the connections and made sure everything was functioning perfectly before they left."

Boiler Repair FAQs, answered by experts

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

To bleed a radiator, first turn off the heat to the system. Then, lay a towel under the valve, open the bleed valve, wait 20 to 30 seconds for air to escape, and gently close the valve. You should repeat this process for every radiator you have in your home. Once your radiator valves have all been closed carefully, you can turn them back on.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

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.
