"Hired them to level one corner of an addition which was sinking and had broken the slab foundation resulting in a crack and non level floor in that corner. They jacked up the sunken corner and supported it with footings. I was generally satisfied with the work. However, the contract specified that they were to then come in and cut out a two foot trench (one foot each side of the ~15' crack in the slab), remove the rubble, drill in rebar to the two sides and refill the trench with concrete. After jacking up the corner, the two management level guys oohed and ahhed about how good the crack looked. They suggested that cutting the trench was not necessary. So, what I got was a guy spent a few hours grinding the two sides of the crack smooth in a few places and then pushing concrete into the crack. I was OK with that. However, that's a LOT of work they had just been relieved of and I felt a price adjustment was appropriate. That was not forthcoming. They charged me the full amount even though they did not have to do a big chunk of work they had signed a contract to do. So, despite what I felt was generally good work, I came away from the experience with a bad taste of "bait and switch". Be prepared for that if you hire them."

Boiler Repair questions, answered by experts

It is usually worth it to repair your HVAC system instead of replacing it. However, one exception is if your system is reaching the end of its life—usually 15 to 25 years. Otherwise, repairs will cost an average of $350, and a full HVAC replacement would total $7,500 in most cases, or between $5,000 and $22,000, depending on the type of system. A reputable HVAC repair company can inspect your system and let you know if replacing it would be more cost-effective.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.

Not every type of baseboard heater needs to be bled. Hydronic baseboard heaters need to have air removed at least occasionally, but electric or gas versions that don’t use water at all don’t need to be bled. There are no pipes or valves on these models to worry about, nor any central boiler. Instead, they use heating elements or other methods to supply direct heat to a room.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.
