"We had a wonderful experience with Comfort Energy! The service person, whose name was Chance, did a thorough evaluation of the problem with a focus on saving us as much money as possible, to either repair or replace our 30-year-old heat furnace. He quickly determined that our inlet filter was too dense (it was a Merv 11 and should have been a Merv 8) and that that was probably causing the heater to go off an on every 5-10 minutes. He then tested and confirmed his hypothesis. He also performed a CO test to make sure there wasn't anything more serious going on. Finally, he gave us a good idea of replacement options, which we should probably do before the next Winter, but not necessarily right away. All in all, this is exactly the kind of assessment we needed, and it cost orders of magnitude less than what was estimated by the first service company we had come out. Chance was great, and Comfort Energy is our go-to for heating and cooling service and/or installation from now on."

"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."

"It's hard to put into a Yelp review how grateful we are to have found these guys. I am in a predicament to say the least. We hired just about the worst contractor we could have hired. We did our due diligence but they were masters of the con. What can u do? (Everlast construction - beware!!) The problems with our HVAC system were many. It wasn't installed to code, and was even set up in a way where if it was left as is, electrical fires and/or the previous hvac shorting out due to being wired so incorrectly. The guys at Jazz were able to take an incorrectly installed system, cut out my old one unit and safely remove it, then install a new hvac with all the corrections to every line. What we have now is an efficient heater that works - and isn't a fire hazard. Imagine that! This isn't even the nicest thing they did for us. Turns out, the ghost of my crooked contractor was still haunting us. We could not pass inspection without a hers test, yet the person hired previously to complete it, disappeared off the map. Jazz got a new one going, and spent several weeks tracking down all the people and paperwork needed to do one from scratch. Needless to say, it was unprecedented for them, no picnic, and they did it happily. Never wavered, never hesitated and always called back and kept us updated. I would recommend them to my mother. These guys will do a good job. They have a kind vibe and I have no reservations in giving them five stars and propping them up. Would hire them again. Thank you jazz! Edit: these guys have come By three separate times to fix more issues left by the previous inept criminally minded people at "Everlast construction." All three times, no charge, super sweet attitude and just supremely helpful. Hire these guys."

"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

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
