"Everyone that we dealt with couldn?t have been nicer. We had a tub to shower conversion which was completed in one day. Matt, the installer, laid a tarp down from the door to our bathroom to protect the floors. He asked for our input when he was installing the shelves and grab bars. After he finished cleaning everything up he explained how to used the new shower head and what to use to clean the surface. The next day we texted him with a question and he immediately answered. We couldn?t be happier with the job done and the professionalism of the company."

We offer professional technicians, same-day installations and 24-hour emergency service. We believe we are the right choice for any of your HVAC, Plumbing, or Electrical needs. Call today to schedule your next appointment!

"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

Boiler Repair questions, answered by experts

The difference between a heat pump and a boiler is simple. A boiler often works with a furnace as part of a heating system. Some HVAC systems also have an AC to cool the home in addition to a boiler. A heat pump is unique as it works as both a heating and cooling system, altering ambient air to a comfortable indoor temperature.

In general, it’s a good idea to bleed air from your heaters at the start of every cold season, before you move your boiler system back into active mode. Early fall is a common time for this task. However, some heating systems don’t need much manual bleeding because of automatic bleed vents and other components.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
