"This was one of the worst remodeling experiences I?ve ever had. I was completely oversold on what they could deliver. I hired them for a bathroom remodel and was promised a spa-like retreat. What I got instead looked like a cheap hotel bathroom. The price was outrageous. They pitched me at around $38,000, and I agreed because I thought I was getting a high-end, premium product. That was absolutely not the case. The materials and design options were extremely limited. They only work with one brand, and they push it aggressively like a bad timeshare presentation. To make matters worse, the price didn?t even include the vanity or any accessories. I had to provide all of that myself. For nearly forty grand, that is completely unacceptable. The workmanship was okay, not great. They were in and out in a day, which was convenient, but it clearly came at the cost of quality. There are spots where the work looks rushed and careless. This is a $15,000 bathroom at most."

"PALMER GAS & OIL in Atkinson NH After 39 years with this company and at every residence since 1986, in new home commercial construction, this company is charging me $189 to remove "their" tanks from my property. I have never been late with a payment in almost 40 years. I found propane at a significantly lower rate, so I had to switch. I highly recommend Irving Oil & Gas, and say, BEWARE of Palmer Gas & Oil. expensive and greedy, no loyalty to good customers."

Boiler Repair questions, answered by experts

You save money on heating oil in a few ways:

  • Make sure your home is well insulated and sealed against drafts and heat leakage.

  • Use a thermostat that’s working properly and calibrated accurately.

  • Increase energy efficiency by insulating your basement and attic.

  • Turn down your thermostat a few degrees.

  • Program your thermostat to lower the heat when you’re not home.

  • Order heating oil during the off-season when prices are likely to be lower.

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.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

The average house radiator has a life span of around 10 to 15 years. However, if you keep up with maintenance, such as bleeding the radiator once per year and removing any signs of rust as needed, your radiator may last 15 to 20 years. Consider hiring a pro to inspect your radiators annually to keep them in the best condition possible.
