"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

Boiler Repair questions, answered by experts

If you have multiple radiators, start by bleeding a first-floor radiator that is farthest from the boiler. Work your way toward the boiler on the first floor before moving to the next floor, where you’ll again start by bleeding the radiator farthest from the boiler. Continue this pattern for radiators on each floor until they’ve all been bled.

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.

When it comes to bleeding a radiator, the goal is to let out trapped air rather than letting out the water. Naturally, some water will dribble out when you open the valve to let out the air. But you don’t want a lot of water to leak out. Just leave the valve open long enough that the hissing noise stops, meaning the air has escaped, and just a dribble of water comes out of the radiator.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

Repair costs typically range from $200 to $1,500, depending on the issue, such as leaks, burner malfunctions, or thermostat failures. Complex repairs involving heat exchanger replacement can be more expensive.
