"It went very well. This is the third time that we have used Green City Heating & A/C. In the past two years they have installed a new gas furnace boiler, two gas fireplace inserts and now a new gas hot water heater. In each instance, Jeff and his crew have been very prompt about attending to our requests and providing us with an estimate. On the day that the work was to be done the work crew has always arrived on time and finished the job as scheduled. They have been very professional to deal with. We are very appreciative that they were able to work us into their schedule so quickly this last time as going without hot water is a bit of an inconvenience. Green City Heating is our first choice when it comes to our home's heating and water systems."

"Greenwood showed up on time for their estimate, and provided a very clear description of our choices in air conditioning and furnace units. Their pricing was about what I had expected to pay, and we were able to schedule an install for 3 weeks out from our estimate. Happily, a new installation window opened up just 2 days from our estimate and Greenwood called to ask if we would want to have our air conditioning installed earlier. The installers came on time, and maintained a very clean workspace over their two day installation. They even swept out our whole garage when they were done. Greenwood took care of scheduling an electrician to come out and scheduling our city inspector as well."

"Mark and his guys helped us install a new AC last summer. They arrived on time and did a great job! So when I was looking for someone to do the maintenance of our furnace, I called them. Todd went above and beyond my expectations. He finished the job and even helped fix my hinge. Both Mark and Todd strike me as very genuine people. And I would definitely hire them again!"

"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"Darrick came out when no one else could and went through my Furnace and Air conditioner. The furnace was fine but found a potential problem with the air conditioner and went out of his way to get the part and fix it right away. I am now looking at having them install a new Thermostat for me. I Highly recommend them and would use them for all my needs."

"Noel replaced two water heaters and installed hot water line so I can wash car with warm water. :) Overall, I am very happy with the quality of his work. He is very patient and took time to do quality work. Before he start on the project he laid down paper on carpet to protect it and he cleaned up everything after he's done. His pricing isn't the cheapest...but I would say average. In line with what other plumbers charge to the same work. I would recommend All Pro Plumbing to anyone and would use them again if I have future plumbing work! Thanks!"

"Blue Flame's team did a great job from the initial consultative assessment, bid and installation. Bid was competitive and fair. The entire team was service oriented and responsive. Installation was quick - two crews sent to enable one day install, complete and left clean and orderly. A+"

"The Installation went very well, and I am still enjoying the benefits of a Heat Pump that was installed. They did a very nice job, very knowledgeable, it didn't take them much time to install the heat pump, they were on time, they cleaned after themselves, & they provided me with good information about how to use the heat pump. I also recommended them to other friends."

Install Boiler questions, answered by experts

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

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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.
