"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 had three top rated heating and air conditioning contractors bid on the installation of air conditioning to my existing heating system. I wanted a quite and efficient two stage ac unit that would work with the variable speed blower in the heating system. Carini was the only contractor that based their bid on a heat load calculation rather than some rules of thumb that tend to oversize the ac system. Their analysis indicated that I needed a three ton unit. The other contractors said that I needed a four or five ton unit, but the blower in the existing furnace and the ductwork would only support a three ton unit. One of the other contractors no bid the job after I said I was not going to install a new furnace and ductwork. The other bidder said they would install a three ton unit but would not guarantee satisfaction. At this point I didn't know who was right. I then contacted my neighbors with AC and the same model home as I have. They all said that they had 3 ton units and we very satisfied. Based on their results I contracted with Carini Heating and Air Conditioning. The installation was planned for one day but actually took 2 and a half days. The installation itself was done in a day and a half but complications with integrating a 2 stage AC unit with a variable speed furnace from another manufacturer required another day to resolve. To his credit, when Jason Baer the project manager found out about the problems integrating the Bryant AC unit with a York furnace he assigned their lead service technician, Anthony DeCarolis to integrate the two units. After several hour of studying both the ac manual and the furnace manual Anthony was able to achieve the expected performance by a combination of DIP switch and jumper setting in both units and the installation of a two stage thermostat. Although I took a few days longer than planned, I am very happy with the overall performance of Carini and my new air conditioner."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

Customers say: True professional

"Josh Medina was very professional in his assessment of my job, was prompt in providing a quotation, and did the installation in less than a day. The price not only was less than four competitors, but also included an upgrade to a two-stage system. I could not be more pleased with the entire job, start to finish. These guys know what they are doing."

"I would absolutely use Jax Mechanical in the future. Justin and Zac were very professional and thorough. I was very hesitant, due to a previous bad encounter with Service Master. Justin and Zac were patient and not condescending. Michael was quick with the bid/estimate and I am grateful for their service. If you need a water heater installed, be assured that Jax Mechanical is the only call you need to make."

"Excellent - We wanted to change our AC/Gas furnace system to a heat pump system and decided to use Tarpy. They provided a very comprehensive review of our needs, and spent additional time with me on the phone to help me choose the best and the most cost effective system for installation. Chris and David arrived on time and were very efficient with removal of the old system and installation of the new. They also corrected a couple of errors due to the previous installation (correcting bad welding on the Freon line, and installing a correct condensate discharge). Chris and David clean up the work area and answered any of my questions before they left. The system has been working great. Thanks Chris and David, and Tarpy!"

Install Boiler FAQs, answered by experts

Costs range from $3,000 to $7,500, depending on system size and efficiency.

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.

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.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

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.
