"These people were real pros. My heating boiler failed - it was only 48 years old!!! They installed a completely new system and lent my tenants heaters while the boiler was on order. They were very good at getting back to me and excellent at explaining the work they would be doing."

"I always have my doubts about what I will get for $39, so went into this deal with low expectations. I have a two story house with basement. The Green Apple crew arrived on time, with a text reminder 1 hour ahead. That always helps. Make sure you know where all your vents are, and that they are accessible (move beds and furniture if they cover a vent, that gives the crew more time to do their job). Tony explained the difference between cleaning the vents, and a deep cleaning of the ductwork. After confirming that I had not had the ducts cleaned in the 20 years I have lived here with 2 dogs, Tony walked through the entire house and took photos inside the ducts. How embarrassing! It was obvious I needed the deep cleaning service (what was that lump in there? We needed to find out). Deep cleaning is more expensive, but when you see how much work it takes for Tony and his energetic assistant, Julian, to really get into and clean the ductwork, you will understand why. They worked steadily for over 2 1/2 hours, and had all the correct equipment to do a very thorough job. They even cut into and repaired the original 1929 ductwork to get at difficult spots without extra charges. Overall, a great job, and today was the first time in months I didn't wake up sneezing. If you are sensitive to chemicals or fragrances, be sure to check the disinfectant before it is used, though there is no hint of it after 24 hours, it has a strong smell when first applied. Again, you only need deep cleaning once every 5 years, so it is worth the .15 cents a day to breath easier. Thanks again to Tony and Julian for a job well done. Pay Tony, tip Julian! (The disgusting lump was a towel I had never owned. That made it worth the price right there.)"

Boiler Repair questions, answered by experts

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

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.

Repair costs range from $200 to $800, depending on the issue and required parts.

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.
