"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"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!"

"I interviewed four solar companies and settled on Solar Energy Services because of price, product, and layout. The installation was excellent and finished on schedule. The installers were polite and excellent workers. I have shown my installation to several neighbors which resulted with several new installations in my neighborhood by this contractor. Everyone was very satisfied with their installation by this contractor."

Install Boiler questions, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.
