"Talk about Top Quality service! From the professionalism of Daniel, to the great job done by Humberto and Ernest. I couldn't have had a better experience in a bad situation. They replaced our steam boiler, and our water tank and did a wonderful job. We have a warm house again thanks to them! Humberto, Ernest, I take my hat off to you!"

"I always trust Chris as my technician to deliver superb service re: my furnace/boiler, hot water tank, split A/C system, and dehumidifier. It's a pleasure to greet him semi-annually, since he's courteous, pleasant, and professional, and since he answers all my questions re: my heating and cooling systems. I trust this talented tech being inside my home and tuning up all these systems. Kudos to Tyler Heating & A/C for hiring Chris as its employee."

"They were great! Even found a way of adding a 40 gallon water heater to a smaller space. Which has been wonderful! They worked in a VERY tight space and got the job done! I highly recommend them! Will be using them to install my central air as well!"

"My first call to this plumber was a very satisfactory experience. I had a whole house water filter and utility sink faucet that needed to be installed. He determined that the filter needed a support bracket that did not come in the box, made an excellent recommendation for redirecting the pipes to secure the filter firmly and make it more accessible. On installing the faucet in the (unheated) garage utility sink he noticed problems with the sink (not designed to be wall-hung and with wrong-sized legs) and pipes (probably broken by freezing). I asked him to install a better sink. He immediately called suppliers and went right out and got the needed bracket and sink and completed the installations. I am very pleased with the results. All the work, including picking up the items at the suppliers within the hour, was completed in a couple of hours. The total cost was fairly high but I feel quite fair for such a job well done. I feel secure that the jobs were very solidly done. I will definitely be calling Bill Duncan for my future plumbing jobs."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

Install Boiler questions, answered by experts

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.

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.

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.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

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.
