"Exceptional service from start to finish! The technician was prompt, professional, and highly knowledgeable. They quickly diagnosed the issue, explained the repair process in simple terms, and had my system up and running in no time. The level of care and attention to detail was impressive, and the pricing was fair and transparent. My home is now perfectly comfortable, and I have peace of mind knowing my HVAC system is in great hands. Highly recommend this company for anyone in need of reliable and high-quality HVAC repair!"

"If I could give Cencal 10 stars - or 20 - I would! This is an ethical, compassionate, caring company owned and staffed by people who act out the company's ethos. Five years ago, when we needed a new dualpac in the middle of a cold winter, we shopped, and then chose Cencal for its responsiveness, clear information, and very competitive pricing. The installation went like a dream, and the service techs spent an entire morning at our home ensuring everything was working better than perfectly. The unit was under contract for a couple of years, and we decided to continue the contract when the "free" servicing expired. So worth the money for the peace of mind knowing our investment is being cared for by responsible reliable folks. I don't have a favorite tech: I appreciate all of them! They show up on time for appointments, and are universally businesslike and friendly. Thank you, Cencal, for making me comfortable in my home. (I'm not mentioning costs because I'm sure they're variable, but I'm on a fixed income and the service is affordable.)"

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"I liked that they were on time, clean and fast. They did quality work. I went on Angie’s List to check their reviews. I would recommend them for anything. I am going to save up money and get my second bathroom and kitchen done by them. They are even going to put my windows in because they have people who can do windows. That’s how good they are. They know everybody. In fact their price was very competitive. I was going to do a demonstration myself. I thought it was going to be a huge amount that I was going to save. He told it’s going to take me 2 days to do it and he could do it in half an hour. It was worth it for me to go and get it done right the first time. I was going to have him redo the cabinets. He told there was nothing wrong with the cabinets. He did recommend someone he knew who could come and stand them down and re-stain them; put new hardware on it if I wanted to. It would be a fraction of the cost then what it would take to replace. He wasn’t out to fill his wallet up by me. He told this is what I need and that’s the best way to do it. They will be the only ones I will use in the future. It was a very positive experience and this guy was absolutely the best."

Install Boiler FAQs, answered by experts

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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.

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.

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.
