"Overall, it was excellent. Jerry (the owner) came out and was very straight forward as to what needs to be done. Price (compared to 6 other companies) could not be beat. Work was scheduled reasonably quickly and went smoothly. Problems were discovered after installation and when made aware, Jerry and his crew made sincere efforts to set it right – and were able to solve the issues in couple of visits. All of the crew and management went out of their way to ensure that we were satisfied with the work and overall result. Would definitely consider Liberty Plumbing for future work."

"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"I am thoroughly impressed with the exceptional service I received from HD Mechanical! Their team recently installed mini splits in my home, and the entire experience was seamless and professional. From the initial consultation to the final installation, their expertise and attention to detail were evident. The installers were courteous, informative, efficient, and ensured a precise installation. The mini splits are now providing comfortable and quiet heating and cooling, exceeding my expectations. I highly recommend them for their accuracy, professionalism, and top-notch service. Five stars and a job well done!"

"We purchased the big deal and everything went well with them.  They did a great job.  Our experience was fine but they were a bit pricey.  I hadn't expected to pay as much because we needed to have some additional work done.  We didn't just pay the $59; it was actually over $700 so that was very expensive.  They did the work on a house we've rented out so I wasn't even there when they came.  I got a phone call and he told me what part of the air conditioner was failing.  We needed to have a lot of work done and wasn't just the maintenance.  The technician was nice and everything but it was just really expensive.  The services were fine and I'm assuming they took take of what they said.  We did have them come out again to install a thermostat and the work on that was fine.  They responded quickly but I had to call again because they were supposed to send me an invoice which they never did.  When I used them again this summer to install a thermostat I had to ask again for a copy of the invoice from the previous year.  I think they were fine with punctuality."

Thermostat screen went blank-furnace and A/C wouldn't come on

Chris arrived within 1 hour of my call and checked the furnace first. He found a blown fuse and no power to low voltage wires inside the unit. He then checked the thermostat and found it was no longer working. Chris replaced the fuses and the thermostat with a similar unit and tested the entire system. He then checked my A/C unit for Freon levels and found and repaired a wire that had come loose.

Chris was very pleasant to work with and explained what he was checking and why as he went along. He explained how the new thermostat worked and provided me with both the installation and operating manuals. Great service!

Install Boiler FAQs, answered by experts

Most installations take 2-5 days, including old system removal and setup.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
