"It went very well; the thorough HVAC system checkup revealed some questionable component that were best suggested to be replace with new ones. I am not confident that my HVAC system is set for more that good performance going forward. I appreciated the non-pressured advice and suggestions in coming to my decisions. Thank you, Joaquin Ortiz."

"It went amazing! Diego assembled a crew of four incredibly hard working guys who came out two days later (Monday), and removed our old system and installed the new one (compressor, furnace, and coil) in a few hours. It was a life saver! The price was very reasonable (I'd previously replaced an AC and furnace at an old house, and paid a couple thousand more). He was on time, worked his butt off, and did great work. He also gave a five year guarantee on anything broken for labor, and the AC and furnace come with 10 years parts that he will coordinate. I will definitely call him again for anything!"

"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."

"Pann was knowledgable, responsive, did all work correctly, on time, and within budget. He went above and beyond by taking care of issues he uncovered that we were not aware were there. He worked with us to come up with the idea of installing an Internet closet that made it possible to have less visible cables and cords running on our walls. The finished project works great and I appreciate having a clean look behind my TV stand. Running the new electric to the detached garage was hard work. Pann crawled around under our house to pull the new wiring through. He even worked within our tight schedule of 2 weeks! Again, everything works great and we will definitely hire again for future needs."

"It went very well. I believe they finished it in one day. The price was very fair and lower than the other two places we checked. The heater works spectacularly according to our tenants. The city inspector came out two days ago and gave it his seal of approval and final inspection passed! Luis the owner is an honest man. He is licensed and does great work. I gladly would refer him to anyone who needs a new heater or Air conditioner! Thanks Luis...."

"Called these guys for what I thought was a Nest issue, and they discovered that my heat exchanger had cracked and I was better off replacing my very old unit with a new one. They provided me with a proposal the same day and I decided to contact a couple other companies for comparison. They confirmed Jazz's findings and provided me their quotes as well. Jazz's bid was very competitive and I was happy to give them my business. On install day, Jazz showed up with two other gentlemen and they wrapped up the installation in one day. System works great. Thanks so much Jazz!"

"I've had Ron service our in-unit furnace for several years now and have always found him extremely conscientious and professional. He also replaced the furnace a couple of years back when it broke and that bigger job also went very well, with a cost that is in line with prices quoted on the Internet. Unlike some other contractors where the agreed time is just an indication of when you can expect to start waiting, Ron has often called on the day to ask if he can show up early, which is great because I'm not waiting around all day."

Install Boiler FAQs, answered by experts

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

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. 

Most installations take 2-5 days, including old system removal and setup.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low.
