"He was a little early, which was good, because we had no heat. We thought it might be the fuse, He checked, and it did need to be replaced. The heat still didn't work. A thermostat we installed was the same as the previous model (installed by another company). He took a long time to explain to us that the model we had wasn't the right one for our system and why. He is the first contractor to explain how our system is different. He replaced the thermostat with a different model. The price for the service call with the Angie's list discount was good. We could have purchased a new thermostat for less, but he told us that, and we went ahead since he was here, honest, and so informative. I will definitely call them again."

"1) Install a 40 gallon water heater 2) Remove the old one 3) Add a platform to elevate the new water heater for draining purposes 4) Install an electrical disconnect (the previous one was outside) 5) Install a water disconnect 6) Add pipes so that both the pressure release valve and the drain at the bottom could drain outside. 7) Drill through the wall so those pipes would reach outside. 8) Make serious adjustments to the existing piping to accommodate the newly raised water heater. I think that pretty much covers it... The service professional was great. Very informative and friendly, worked efficiently, and kept us filled in on what he was doing. He left the area around the water heater cleaner than he found it. They diagnosed and replaced the water heater on the same day I requested the work. The dispatcher was kind and informative and the final price was very close to the original estimate she provided. I would definitely recommend their services. And the whole water heater area looks so much more organized and neat then it did before. The price is high compared to a standard water heater replacement, but like I said, we needed a lot of updates. Price includes the new unit and all supplies."

"Tuck & Howell was responsive and timely in both the initial service call and in the repair work. They were cooperative when we had to delay the work multiple times. The repair work was done for half of the estimate we got from another company and we have had no problems since the repair. The workers were professional and considerate."

"I am extremely glad that I chose Mike's Heating and Air, because Mark (Mike's son) and Andy worked hard to make sure that I was satisfied at every step in the process. Seldom am I overwhelmingly impressed with the level of both quality and value of a service, but Mike's Heating and Air warrants the highest ratings in every category! I now have a high efficiency and very quiet central heating and cooling system in my house after a turn-key, no surprises experience with Mike. I will definitely choose Mike in the future and would recommend him to anyone looking to install a HVAC system."

"SUMMARY: HIGH QUALITY WORK WITH LARGE PRICETAG. Corley plumber arrived on time. Their plumber was polite and offered several options for the repair. The repair was completed correctly and in a timely manner. Work area was cleaned after plumbing work was completed. No problems with the repair since it was completed which was several years ago. In short, I would give them FIVE STARS FOR THE QUALITY OF THEIR WORK. I would hire them again in an EMERGENCY (which is why I hired them for this work; the usual plumbers I use were unavailable), but NOT for non-emergency work. My reason for not wanting to use them for routine work is that their prices were OUTRAGEOUS and I'm not a miser (this is why I removed one star in my rating). The few replacement parts needed would have been nominal cost at a plumbing supply store. That means their labor was $200+/hr for installing compression fit connections which is even easier and quicker than gluing PVC pipes together (no heavy lifting; nothing complicated; easy access to pipes). I've had other plumbing jobs that were too big for me to do. I've found competent plumbers that do a great job (quality like Corley's) for half the price if you are willing to wait a day or two. Lesson: Instant gratification has a high price tag. FYI: They will charge for the cost estimate if you don't have them do the repair."

"The guys worked tirelessly to complete it all. My new heat pump and my sisters' were installed in a very timely manner with a big enough crew to accomplish it all promptly, and so far are working fine. Vaughn and Lucas came to my house from my mom's to install the capacitor on a Friday afternoon when I'm sure they wanted to get done early. Everything is going well at present, though my mother will need a new coil which is in process, but her air is working and the guys said they would return if anything else was needed. They all went above and beyond, helping me to seal up cracks and crevices and to put new screen wire over the vents due to the snakes, which I had started doing myself. They were courteous, respectful and informative, and stayed till the job was done! Thanks to Rhonda and Brandy at the phones, and to Jason and Andy as well!"

Install Boiler FAQs, answered by experts

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

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.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

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.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.
