We pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!

"I was a little disappointed because I hired this company based on the reviews and the issue was not resolved the first time the pro came out and I had to pay twice for him to come back to adjust the same issue. I would have to say that maybe my pro was not as experienced in handling my heat issue but I would not dissuade others to not hire this company."

"Can't really find the words to express my full satisfaction with Kalthoff Handyman Services. I hired them to rebuild a very difficult deck---hillside/rock. They worked very hard to build a beautiful deck---quite an accomplishment. They worked thru late fall with very cold temperatures---never with a complaint. The price was fair and they never found reasons to raise the price. I was so pleased I asked them to do other jobs---new kitchen, 1.5 bathrooms (one was down to the studs), flooring in 2 bedrooms, front steps, insulation. Prices remained fair throughout. Always done professionally and with attention to detail/finishes. Tile work is beautiful/first rate. In the winter, the water froze (pipe in ground). They fixed it (found a way to solve the problem)---no charge. Really quite superior and I am fully satisfied with their work. Cory has the highest standards and completes whatever he says. I recommend them most highly and feel very fortunate to have found them."

Boiler Repair questions, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

There are many signs and symptoms to look out for that can indicate that your HVAC system needs repair, including the following:

  • Your indoor air is uncomfortably hot or cold.

  • Your energy bills suddenly increase without explanation.

  • Your AC is blowing warm air or not blowing air at all.

  • You notice leaks around your HVAC equipment.

  • Your equipment makes unusual noises during operation.

  • You notice strange odors coming from your equipment.

  • You notice that the humidity in your home is higher than normal.

  • The thermostat no longer seems to match the actual temperature.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.
