"While having my siding removed and replaced, decided to insulate the exterior walls. They coordinated with the painter and checked the weather for when the project could be done. Also, the estimate was given several months in advance and was still honored once the project got going. They needed to come out twice to install the insulation because the siding took time to come off the house, but they were more than willing to work with the painter's schedule to make sure things got done in a timely fashion. Friendly folks who take time to answer questions and did excellent work getting the house insulated and now operating efficiently."

"I had a hot water heater replaced a few years ago by Mission and had a crucial part stop working. While the part was still under warranty, I paid for a service fee to have it replaced at a fair cost (just labor, the part was under warranty). Unfortunately, the replacement part failed in a short time. Long story short, they came back out and spent time on two different days correcting the problem and replacing the part. It really was just one of those odd-ball everything goes wrong kind of malfunction, although it was no fault of the company. In the end, Mission Plumbing sent me an invoice with a zero balance. It was quite the headache for them, but they honored the warranty to the max even though it cost several man-hours. I will definitely use them for future needs."

"He came in and looked at the air conditioner and the furnace and pulled out the book and calculator. He suggested me all I wanted and he gave me the best quote for it. I am happy with them. They were prompt and the guy was on time for his call. He got down to work and didn’t mess around. He didn’t try to oversell me."

"Prior to calling Bob, we had several guys come in to give us estimates. Bob's estimate was by far the best and the work he did was top quality. He and his guys moved my existing furnace to a new location int he basement and installed a new AC. They also moved the hot water heater. I am very pleased with his service. They were prefessional and respectful. Bob is a straight shooter. Absolutely no BS! I will be using him for ALL of my future HVAC needs. I HIGHLY recommend you call him and have him come give you an estimate if you need service, repair or replacement.

Install Boiler FAQs, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

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.
