"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!"

"This is the first time in many years that I have signed in to Angi. I saw that I still had this pending review to complete. Let me just say, this company was excellent. Would hire them again for a central aircon and heating install project. Middle range price but I think excellent work that you can trust."

"The service tech that came to our house, John, was very courteous, very knowledgeable and detected several issues that he explained in detail and it was easy to concur with his assessments. He found a big clog in a very old pipe, which had broken as he was inspecting it. This clog had been giving us problem and was preventing the air from turning on. He ran to home depot, bought a replacement part and installed it, at no additional charge! He also vacuumed the heating unit and installed a new latch to hold the filter in place. He took the time to explain about the need to ensure the filter is secure so dirt and dust does not work its way into the main unit (Which would be very bad!). He examined the outside air conditioner and we scheduled another appointment in 6 months for a nice general check up. The outside unit may have a leak, which we were previously aware of, but he provided us additional details and let us know what our future options may be. We decided in 6 months, when they return for the semi-annual service we signed up for, that we could see how everything is looking. Very happy with the experience with Magnolia!"

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!

"Brian came over to give us an estimate. He’s very friendly and polite, easy to work with. Answered all our questions and gave his recommendation without being pushy. Later we spoke with the owner, Dave, on the phone, who accommodated all our needs, gave us a great deal and upgraded our system with a medical grade filter at no extra cost. Pedro and his crew did the installation within a day. They were on time, worked fast, were super courteous, and cleaned everything up at the end. All in all everyone was very efficient. I was very pleased with their job and would hire them again without hesitation."

"Very well. Technician, John Ruiz, showed up on time - as scheduled, was very polite, thorough, informative, and very professional. John pointed out some potential safety issues with our aging system and made some recommendations. My wife and I were very impressed with his explanations of his findings in our system as he showed us discrepancies and took several pictures of problem areas that would have been difficult to access. I also want to comment that the installation team, Adam Palazzola and Diego V. were nothing short of outstanding! It only took them 2 days of ripping out the old system and installing the new. Overall - we are very pleased with Home Comfort USA."

"Installation was smoooth, it was done within a day. There was high pressure sales involed which I succumbed into as the sales guys were saying that I had fiber damage in my ducting and since I have kids in the house they said that it was very crucial that I do the change now. It was my fault to not do any more pricing research hence I was a bit gouged."

"We needed a new heater and decided to also add A/C - went great. The sales person was very helpful and knowledgeable about our options and helped us choose a best fit. We chose a more expensive option because the maintenance and repair on the Carrier solution was the best. The Carrier company who provided the equipment also provided a good financing fit. The installation crew were a great bunch of folks, efficient, friendly and left our job site immaculate."

Install Boiler questions, answered by experts

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.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

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.
