"This is a family owned small business. They are friendly, professional, punctual, and really know their stuff. All at a very fair price. My AC had been getting worse every year until last year. HVAC Utor came out and fixed it. It ran better than ever before. This year it was just blowing air so I called again. Same great service as last year. Rachel kept me informed so I knew when they would be here. The problem turned out to be the new thermostat I had installed a couple of months ago. Diego had it figured out and fixed in 15 minutes. I can't say enough good about this company and the people who run it. They're the best!"

"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."

"Called these guys for what I thought was a Nest issue, and they discovered that my heat exchanger had cracked and I was better off replacing my very old unit with a new one. They provided me with a proposal the same day and I decided to contact a couple other companies for comparison. They confirmed Jazz's findings and provided me their quotes as well. Jazz's bid was very competitive and I was happy to give them my business. On install day, Jazz showed up with two other gentlemen and they wrapped up the installation in one day. System works great. Thanks so much Jazz!"

Install Boiler FAQs, answered by experts

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.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

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.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.
