"I called Mehmet based on the Angie's list recommendation and the terrific reviews. Mehmet worked around my work schedule and came after 5. He identified the problem and installed a new capasitor. He was in and out of here in 30 mins. A week earlier a rip/off big company (Varsity) claimed the unit could not be fixed for under $3500 and recommended I install a whole new system for $11,000. Mehmet's skill, reasonable price and honesty were well appreciated here."

"It was a pleasure meeting Muhammad from Heating & Cooling Pros LLC. By sending him some pictures and giving him some information he knew the problem with my boiler. This is important to me … He did not charge per hour, gave me a price which was very reasonable. I felt peace of mind knowing he was honest and was not over charging me, also he was on time and did not make a mess. I did not have to clean up after he left. Muhammad is definitely very knowledgeable of his work and highly recommend him and his company."

"Let me just say that I am so lucky to find a Hvac company like Anthony's. I had 3 other contractors say my gas boiler needs to be replaced without really inspecting what was wrong. I found Patience hvac Inc when I was about to lose hope. He is super fair and through, went over explanations of each parts replacement needed, did maintenance clean up of boiler and extra miles on my 30 years old boile now it is back life just like new. I am really thankful to Anthony. He is quick, prompt, sincere and humble. Trust me call this guy, You will save lots of money and headache."

"Mo was a very able, responsive and professional technician who installed our furnace in one day and our new boiler two days later. He patiently answered my many questions, walked me through why we needed two new units (instead of repairing our old ones) and worked well and efficiently. It was painful to have to pay that much money at once for a furnace and a boiler, but Mo made it as positive an experience as it could have been. I am grateful to him and his assistant for their work and professionalism."

"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"

"We had Mark from Panda HVAC come to clean our two HVAC units for winter use. We knew there was an existing problem with one of the units and that we were on the verge of having to replace it. Mark confirmed our suspicions, and also noticed some other issues that needed to be addressed. He didn't pressure us at all, and when we requested a quote for a replacement unit, he was prompt and fair and found us the best price. His team showed up promptly on the day we scheduled and finished ahead of schedule, replacing the heater with a minimum of downtime -- good thing, as it was one of the coldest days of the year and about to get colder! They were professional, courteous, and thorough. I will definitely hire Panda HVAC again."

"Billy from Elite Piping Solutions was a pleasure to work with. He is pleasant to speak to, thoroughly professional, explains things completely, and addressed additional items that would have become problems down the road. He brought on other professionals as needed without putting the burden for that on us. We expected the new heating appliances to serve us efficiently for many years to come!"

"This Company is top notch! They quickly responded to my urgent message in regard to no heat in the house and had the service guy arrive to the door right after completing another job. They were very professional and did the repair in no time and price quoted over the phone was exactly what was charged for the service. We will definitely call this Company again for any boiler repairs. Thank you!"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

Install Boiler FAQs, answered by experts

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

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.

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