"This was by far the best experience I've had when it involves repairs. My heater had been broken for a year. Because I'm on a fixed income, I couldn't afford to replace it. Quotes from others all recommended replacement. HD Mechanical gave me an estimate for repair and it was fixed right away, an at a fair price. Brandon and Tim are the best and are professional and dedicated to getting the job done without trying to upsell to unnecessary replacement. It works fantastic. They also happened to fix my ac as well, with no cost to me. If you are a woman alone, hire this company. They're honest and fair, and provide great service"

"These guys saved us during the recent heatwave. I looked for days for someone to come help us service our airconditioner, which was working....except for the cold air part. These guys were so easy to get in touch with and they put us on the schedule for the next day. They took a look and the fix was really easy. They serviced the AC, made some recommendations for future upgrades (but made sure to let us know they weren't emergencies) and left us with a house full of cold air. It was one of the easiest home services we've had in our new house. HIGHLY RECOMMEND."

"Everyone at Baltica was responsive and eager to please.  Calls and emails were returned punctually in every instance.  Everyone I communicated with was professional and accommodating. 
I called initially to discuss moving to a tankless water heater, but a personal review of my property showed that it was not possible.  Kevin Phidayev, with whom I made the arrangements, was eager to accommodate my product needs, financial needs, and scheduling needs.  Kevin was ultra-responsive to every call, email or request.
The installer, Marius, was particularly pleasant.  He showed up on time every time.  He looked professional, was knowledgeable, and he got the job done on time.  He was happy to accommodate my neighbors in the condo who would be without water for a brief time. Marius left my home clean, and he protected my new floors from damage. 
To be honest, I did not do any comparative shopping for pricing purposes because I was so impressed with my initial contact with this company.  I got all kinds of upgrades I never knew existed.  Marius installed a pressure relief valve, new water valve, new stainless steel flexible water and gas supply lines, and new double earthquake straps, among other things. I have learned from bitter experience that you get what you pay for.  If this water heater seemed costlier than I expected (my only "B" rating), in the end I believe I got my money's worth. 
The level and quality of customer service is unique in my experience.  Truly outstanding.  I have already referred business to Baltica, and would do so again without hesitation."

"Had a fantastic time working with Home Comfort USA. Their associate, Max, was prompt, very professional, and provided a personal touch to his service. He not only identified and repaired broken components of my home air conditioner but also advised outside factors affecting the unit along with advice to improve the unit's performance over its lifetime. The unit went from nonfunctional to running better than it has for years inside of an afternoon. Max went the extra mile to make sure that my family and I were taken care of and to provide a personalized experience. I definitely recommend working with Home Comfort USA."

"After many roofing estimates that were incredibly high and came with either no financing or high interest financing, I stumbled upon Zen Builders. Simon was attentive, knowledgeable, and on top of his game. My roof was completed in three days, it's beautiful, and there were NO LEAKS when the rains came a few days later. The workers were professional, considerate, and the clean up was amazing. No trace of having construction in my yard. Because I was so happy with the work, I mentioned to Simon that I would love to have him come back and do a few more projects. I ended up with an even better financing option (both loans are well-within my budget) and a GORGEOUS new patio cover complete with a surprise ceiling fan in the middle! The patio is now white, and they painted the trim of my house to match. They also fixed my heating/AC ducts, insulated my attic, and for free, added plywood, so I can actually store items up there. I have never had an issue getting ahold of Simon or his sister, Kineret (Kerry). When there was an adjustment needed to the air ducts, the workers came out quickly (amid the COVID-19 quarantine) and simply fixed it! I couldn't ask for more! All work took less than a month to complete and I never felt pressured, ignored, or bamboozled. I have recommended Zen Builders to many of my friends. I hope they recover from the imposed quarantine to continue to provide excellent service."

Boiler Repair questions, answered by experts

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

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.

Costs depend on issue severity, parts needed, and labor rates.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.
