"Brandon came out on a Sunday and looked over the job site for details needed to present an estimate. Within a day I had the estimate with 3 options from low to high, all of which were reasonable the only difference being what equipment I wanted to install. Option #1 and #2 were lower end brands that were less expensive but since the difference in price betwee Option #1 and Option #3 was about $1400, I went to Option #3 which was their top tier brand, Carrier that clearly is an industry leader and trusted brand for longevity. I was installing a SINGLE ductless to cool a standard bedroom size room with a 18,000 BTU unit. The job took a total of about 5 hours since they were mounting the unit in a second floor bedroom and they needed to run the power/refrigerant lines two stories down to the compressor mounted on the wall. Everyone from Office Staff Jim to installers were absolutely wonderful to deal with. You can trust this company."

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

Thermostat screen went blank-furnace and A/C wouldn't come on

Chris arrived within 1 hour of my call and checked the furnace first. He found a blown fuse and no power to low voltage wires inside the unit. He then checked the thermostat and found it was no longer working. Chris replaced the fuses and the thermostat with a similar unit and tested the entire system. He then checked my A/C unit for Freon levels and found and repaired a wire that had come loose.

Chris was very pleasant to work with and explained what he was checking and why as he went along. He explained how the new thermostat worked and provided me with both the installation and operating manuals. Great service!

"Evening of Valentine's Day we learned our water heater had broken.
Called Bob & Marc the next morning and had an appointment of 3 pm. They were available earlier, but I could not get out of work any earlier.
Spencer was on time and got right to work. He was very professional, careful and friendly.
He assessed that the water heater was broken, drained and removed the old one and installed the new one.
He made sure that the TPM piping was exact, fit and would last. He was very helpful in explaining what he was doing and was even very helpful in providing advice on how to extend the life of this new water heater.
He cleaned up and all that was left was a professionally installed water heater that has been working great.
Thanks for the quick, friendly service (also be sure to use the 10% off coupon found on their  Angie's list page).

"Our outdoor barbeque/kitchen in the pool area was just done by Best Builders Group who was referred to us by a co-worker who hired them for his last remodeling project at his house and he was very happy with everything they did. Our remodeling project was a large scale remodeling project to our opinion BUT to Best Builders Group it was a normal size project and they provided all the required attention to detail and great working capabilities. We had some concerns on the plumbing & electrical but Zohar took care of all of them in a very professional manner. Part of the work was to build a custom fire pit and Zohar was always nice enough to do whatever we asked. All the workers on the other hand… always made sure to clean up & they never left the house without the cleaning task. The installations was done perfectly, professionally, clean and with perfection. This remodeling project came out to be such a wonderful entertaining spot of the house and I strongly recommend them."

"Woke up that morning and I found out that I had not water! I looked at my water heater tried to figure out was was wrong. I know nothing about plumbing so I was very hesitant on calling a plumber. I was afraid anyone would try to overcharge me OR sell me a new water heater. I found Pro Plumbing Heating and Air and decided to give them a try. I looked up their website and saw that they are a family owned company and been in the business for a long time. From my initial call to book through the appointment down to the actual appointment so I was very impressed! The lady I called to book my appointment was so polite and courteous she made me feel at ease letting me know that I would be taken care of. I was given a same day appointment and my technician arrived even earlier than I expected. The technician that helped me was so knowledgeable, turned out that that I only needed to light the pilot light on my water heater! He didn't try to push anything on me that I didn't want. He answered all my questions very patiently and made sure I was satisfied with everything. Thank you All Pro Plumbing! I will definitely be calling you in the future for any of my plumbing or AC needs!"

"They were really good. They were helpful and really quick on getting back to us. We called him on a Tuesday and they came out on Saturday to get the job done. There was one hiccup with the installation. They felt that they would be able to use the hand lift, but when they figured out they wouldn't be able to use the hand lift, most instantly he went and called for a crane and we had a crane service set up the same day, so nothing slipped on the schedule. They were not the cheapest, but their service was satisfactory."

Install Boiler FAQs, answered by experts

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

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.

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.
