"Duke did a great job at a fair price. We needed AC and decided to replace our old furnace at the same time. In addition Duke wrapped with insulating bubble wrap our old ducts that were exposed. He tied the drip line into our existing downspout in a neat fashion. I'd highly recommend him (he's a fellow submarine vet too!!)."

"We purchased the $49.99 service call. It was very easy to schedule, and we had someone out within a couple of days. The gentleman who came out was very professional and communicated everything that he was doing and finding. At the end, he provided several options for our furnace. One was to just replace the part that was causing our immediate problem; however, our furnace was 27 years old and there were signs that a couple of other key parts were on their last legs. The other options were to replace the furnace with different types of furnaces. I wasn't comfortable making the call on what we would do at the end of the service call and that was fine. There was no hard sell to make an option then and there. I really appreciated that.
After discussing it, my husband and I decided to replace the furnace with one of the options provided. We called the next day and they sent a couple of folks to replace it within a few days. The two gentleman were professional and thorough, and cleaned up everything before they left. They installed our Nest thermometer rather than the thermometer that came with the furnace, and everything has been working great.

"Peter did a great job installing two new furnaces at our house.  Install took a little longer than expected due to venting issues that were beyond his control.  Overall - he was in constant communication throughout the job and his crew was very professional.

"It went amazing! Diego assembled a crew of four incredibly hard working guys who came out two days later (Monday), and removed our old system and installed the new one (compressor, furnace, and coil) in a few hours. It was a life saver! The price was very reasonable (I'd previously replaced an AC and furnace at an old house, and paid a couple thousand more). He was on time, worked his butt off, and did great work. He also gave a five year guarantee on anything broken for labor, and the AC and furnace come with 10 years parts that he will coordinate. I will definitely call him again for anything!"

"Had a wonderful experience when Joaquin, Ben and Anthony of ABC Cooling, Heating & Plumbing came out to install my mini-split heat pump unit this week. Professional, respectful, skilled at their craft, and with attention to detail. They communicated clearly, kept mess to a minimum, and cleaned up thoroughly after themselves. Highly recommended!"

"The technicians that came to install our HVAC system were super friendly and accommodating to my many requests about locations of the furnace, vent pipes, the condenser wiring, piping, and the condenser itself. When I asked for a 90 degree boot feeding two registers so the piping could stay high, a technician made a run to a store and found them. I want to give a shout out to Danny Aguilar who installed the furnace with Edgar and Victor. Grant Duran with Jose and Richard did an amazing job installing the vent pipes. Finally Adolph Garcia with Gabriel and later several other technicians I previously mentioned all worked to install the AC system (condenser and its plumbing + electrical). They worked late into the day to complete the job. I was very demanding in where I wanted things installed and requested changes on a regular basis but in all cases I was accommodated."

"Pann was knowledgable, responsive, did all work correctly, on time, and within budget. He went above and beyond by taking care of issues he uncovered that we were not aware were there. He worked with us to come up with the idea of installing an Internet closet that made it possible to have less visible cables and cords running on our walls. The finished project works great and I appreciate having a clean look behind my TV stand. Running the new electric to the detached garage was hard work. Pann crawled around under our house to pull the new wiring through. He even worked within our tight schedule of 2 weeks! Again, everything works great and we will definitely hire again for future needs."

"Great! Tony called in advance & was very prompt. Personable and professional, he quickly hooked up his equipment and let the machines do their work, which took about 30 minutes for our 1400 SF house. He took photos of the intake duct so we could see their condition. I will be scheduling a manual deep cleaning of the whole system next!"

Install Boiler FAQs, answered by experts

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

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.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.
