"I signed a contract on the first week of June to have PIC Home ?Pros? remodel 3 bathrooms. They stayed for a week in the middle of September, and stopped coming, leaving a vanity in one bathroom, and a shower door in another bathroom completely uninstalled. On the last day here, I was told shower door still has not been manufactured yet, but would take a couple of weeks. They told me that it would cost $150 to have them come back to finish installation, even though contract was for them to complete the work. They ignored my emails to them, so after waiting for 3 weeks and receiving response to my email, I called them, and was told that the shower door is not ready, and even though it?s been 4 months since it was supposed to be ordered, there is still no ETA. I asked that they come back to install the vanity, since we still have no sink in one bathroom. I was told that would cost another $650 to come back and install it. They will work until they are paid in full, then abandon you. "

Install Boiler questions, answered by experts

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

Most installations take 2-5 days, including old system removal and setup.
