"Very prompt in responding to my initial inquiry (Sunday no less) and salesman was terrific. Installation took 2 full days by a team that seemed professional and knowledgeable. I was shocked however by the fact that 2 men on the installation team smoked all day long. My property is rural with no fire hydrants - the prospect of fire is terrifying to me. At the end of the 2 days the system was installed but it took an additional technician coming out after the crew had left to get the system functional."

"This was, perhaps, the best experience ever. From scheduling to installation everything was taken into consideration: schedule, budget, what I wanted, what the HOA wanted, permits and new electoral installations. Their personal from the office to the installers were kind, informative, great at problem solving and considerate of my premises. The heat pump itself is the absolute best. Can't wait to see my PGE bill. Loved the crew: JP, MARIO, ALEC and STEVE."

"Their technician showed me the solution quickly. A small rotating piece needed to be adjusted. For all I knew, he could gave told me the system had to be replaced. He quickly completed the job for lasting satisfactory results. I'm planning to have them do duct cleaning soon because I was impressed with their honesty."

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Ezra at Landmark construction energy crew is a perfect company in my book! I honestly recommend Ezra and his team of plumbers, because he his honesty and integrity, qualities that are sadly hard to find these days! Ezra was extremely helpful and knowledgeable about the tankless water heater system that we installed, and he was kind enough to come over and take a look at our new unit after it was installed and to check with us that the monthly bills came down as well. In addition to that, Ezra installed our new tankless water heater with the remote control that connects outside the tankless water heater. Because the remote control was not waterproof and if it will be installed inside the water heater, it would short circuit if it got wet enough. Thank you Ezra for going above and beyond for a "customer" who didn't even get to use you! Much appreciated. I will definitely be using Landmark construction energy crew to service my new tankless water heater when it needs it!"

Install Boiler FAQs, answered by experts

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.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

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.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

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.
