"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

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

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.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.
