"Brian built a addition consisting of a garage with and finished upstairs. I would say that the end result is amazing and Brian has always responded to me when I needed him. We moved into the area and we bought a farm with many challenges over the first few years and Brian and his crew were there for us on every occasion. Brian also install my metal roof and also fixed a chimney that needed a insert due to a past fire. I could go on with the projects Brian has been there for me on but the list seems endless.

"I strongly caution anyone considering doing business with this company. I gave them a deposit of $4,428.65, and when I canceled a week later they kept almost $900 of it even though my service was not for another 6 weeks. You do sign a very simple, clearly stated document that says: should you cancel beyond three business days, you understand your deposit is non-refundable. Northern Basements may choose to refund depending on cancellation circumstances I fully acknowledge that I canceled a few days outside that window, but I hoped an honest company that cares about customers and referrals would choose to provide a full refund. I am a sucker for hoping that. They chose to risk my impression, referral, and review for $885.53. If nothing else comes out of this, I hope everyone reading at least goes in knowing that this statement on their contract is a real threat and your deposit is a hostage. Even Air b and bs offer full refunds on deposits within just a few days of their arrival date. 3 days to cancel with service not scheduled for 6 weeks out, Come on man. No materials were used. No service workers time was taken. The manager justified the 20% withholding as credit card fees, restocking fees, time and resources for the estimate, and administrative fees. I wholly accepted responsibility for the credit card fees and time of Paul, the gentleman who performed the assessment, and I offered to settle at 10%. I still believe any reputable company would have provided a full refund at this point in a project, or at most deduct the credit card fees because nothing more went into this beyond what would have normally been a free estimate. The further arguments the manager made for the additional fees were the scheduling of their team and the allocation of materials for my project. Complete nonsense, especially when the project was not set for 6 weeks away. Because they had my deposit hostage, they had control over how much they decided they wanted to keep, it was completely arbitrary, and they kept almost $900 of my money without providing anything. If they wanted to cover their credit card transaction fees, fine, at most 6%, but the rest is absolute robbery. The only solace I can find in this loss of almost $900 now is that I did not spend another $13,000 with them. I tried to call Paul after speaking with the manager to ask if he could do me a favor and try to reason with the manager on my behalf because he seemed nice enough. No answer. No callback. I will never seek out their services again and I will actively discourage others from doing so but, based on my experience, I expect they do not care."

Boiler Repair questions, answered by experts

A heating expert will be able to clarify whether it's worth the cost of replacing your radiator based on the cost of repairs. Between parts and labor, you'll pay between $250 and $2,500 for a new radiator depending on the type of unit. If the long-term costs of fixing a radiator are higher than replacement, it's best to update your model.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.
