"I was in the need of getting a garbage disposal installed and an electrical socket since there was only a hardwire access that was very old wiring from when the house was originally built. These guys were very professional prompts they came out right away! The prices were reasonable and I really appreciated their help. I had already contacted two other plumbers to see about the job. They charged me to come out and they didn’t get the work done but these guys they came out they looked at everything they didn’t charge me just to just diagnose it they told me upfront what it was gonna cost and we were able to come to an agreement.

Boiler Repair questions, answered by experts

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.

If you don't clean a boiler, you may have higher energy bills or no heat. A dirty boiler is inefficient and can't properly maintain a heating system. It may break down more often due to corrosion or clogs from soot and oil buildup. Cleaning a boiler improves its performance. The cost to replace a boiler can be expensive, so keeping it clean is a cost-effective practice.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.  

With proper maintenance, boilers last for around 15 years on average. A cast iron boiler may last longer, over 20 years, but you should always consider the efficiency of older boilers and opt to replace an old one if it’s significantly lower than newer, high-efficiency boilers. Otherwise, you’ll be spending more on your utility bills each month.
