"The installation went well. The crew arrived on time and completed the job on schedule. Included was a one year guarantee on labor and 5 years on the unit. The price was fair. We will use the company again for future jobs."

"Braido is a nice family run company.  I had the original 25 year old furnace and AC. I has the last house on the block to replace them.  Needed to get it done before winter.  They showed up the day I called for an estimate, took measurements, checked old system and discussed in detail my options for a replacement system.   No pressure to sell me the best as we will down size in a few years. A few days later quotes for two systems arrived. I was able to scheduled an installation that fit my schedule.  It was your typical one day job.  Everything went smoothly with the installation, and the old hardware was taken away.  I like this company and recommend them, I give them and A.

Install Boiler questions, answered by experts

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

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.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.
