Install Boiler questions, answered by experts

If you have a closed-system boiler that needs an expansion tank to work, you cannot run your boiler without it (not without the risk of extensive damage and even explosions). Your options include moving the boiler to another spot, rerouting boiler piping to a more open area, or completing a remodel around the boiler to create more space for the tank.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Modern boilers average around 20 years of use before failing, with some hitting 25 to 30 years. Older boilers, however, can last up to 50 years because they are often made from ultra-durable cast iron. Newer models are made from steel alloy and related components, which are great for withstanding high pressure levels and hot temperatures but offer a slightly lower life span.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
