"Alpine Heating and Cooling replaced our old two-zone heating and cooling system with a new energy efficient one. The team of installers arrived as scheduled, and the installation was done quickly and professionally. Alpine applied for the permits and we passed the inspection with flying colors. Their pricing was very competitive. We are very happy with the new system and reduced utility bills."

"I had the best experience with H2Bros Plumbing and Heating. I hired them to install Navien combi unit to replace my old boiler and water heater. Genaro and Javin were very knowledgeable, professional, and polite from the start. They did an awesome job by installing all the needed parts by the code and very neat. Even though I know some plumbing companies cut corners and not install all additional components that recommended by Navien. Very reasonably priced for the job they did. I would definitely recommend them for similar jobs or any plumbing and heating projects. Please see the photo of the finished job for yourself."

"Nick and the team were working hard for 2 days trying to install the boiler and route all the pipes in a very tight space. After two days we got a new boiler which hopefully will last long. 5 years worry-free warranty from Valairco is another reason I went with this company."

"Excellent HVAC and Solar installation services! They did a great job installing a new HVAC system for us a few years ago, so we sought their services again for Solar installation. They were very professional both times: provided pricing right away, technicians were polite, and job was completed in a thorough yet efficient manner. Jobs well done!"

Replacing an outdoor air conditioner with a high efficiency, consumer reported top rated American Standard unit.  Level, wired properly, and completed beyond code and required standards.  Thank goodness for a team that cares and loves what they do AND our customers.
Great technicians who have amazing skill and are just good humans too.

"“Awesome company, great work. I will hire again for other home improvement jobs.” Installers were professional, on-time and clean. This is a world-class organization. They only promised and delivered on the services they could perform. Their email quoting system is one of the best. The home owner will know upfront the cost of the job,"

Install Boiler questions, answered by experts

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.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

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.
