"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

"The issue was a stuck Shower knob The final bill was $960. I ended up paying $800. Mason insisted on changing the cartridge- He over charged me on the cartridge and didn't give a receipt. His charge for the cartridge was $600. Rest of the cost was his labor. I am not happy with the price."

Boiler Repair questions, answered by experts

To bleed a radiator, first turn off the heat to the system. Then, lay a towel under the valve, open the bleed valve, wait 20 to 30 seconds for air to escape, and gently close the valve. You should repeat this process for every radiator you have in your home. Once your radiator valves have all been closed carefully, you can turn them back on.

Yes, it is OK to turn off some radiators, and you’ll save money on heating costs if you make it a regular habit to turn your radiators off in unused rooms that don’t need heat. That said, turn them back on when you need to heat your whole home instead of cranking up the dial on the ones you haven’t closed to compensate. The latter will result in higher heating costs and more wear and tear on your system.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

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.
