"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."

"Bo and Bryan arrived promptly at 8:00am to install my new furnace. They removed the 15 year old furnace and set the new one in place. It was slightly smaller than the old furnace so they had to fabricate a new transition between the cooling coil casing and the furnace. They completed the wiring including the control wiring for the humidifier. They programed the controls and test fired the furnace. They were finished about noon. They thoroughly cleaned the area. The installation looks great. Both Bo and Bryan were very friendly and cooperative with how I wanted the installation completed. I will definitely use Mission Plumbing heating & Cooling for my future HVAC services. I am extremely satisfied with the job they provided."

"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

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
