"From the first point of contact, Valley Heating was a pleasure to deal with. Zac came by take the initial look for the estimate and was so friendly, helpful, and professional. Once we received the estimate, I was blown away by how professional and organized the company was - the matrix of options, the fast and clear communication, the scheduling - it was all so unlike the other contractors I'd been dealing with through my renovation. Once the job started, I continued to be pleased. Eugene (Gene) led the crew and did a fantastic job over the 5 days they were at our house. The work was precise, clean, accurate, and on time and they delivered exactly what they said they would. Just like Zac, the crew was a pleasure to deal with. They kept our house amazingly clean even during a rainy day and having to deal with our dirt floor basement. I have a solid understanding of how everything works and couldn't be happier. This is hands down the best contractor I've ever dealt with and I plan to use them again for electrical work and make many recommendations."

"We purchased the $49.99 service call. It was very easy to schedule, and we had someone out within a couple of days. The gentleman who came out was very professional and communicated everything that he was doing and finding. At the end, he provided several options for our furnace. One was to just replace the part that was causing our immediate problem; however, our furnace was 27 years old and there were signs that a couple of other key parts were on their last legs. The other options were to replace the furnace with different types of furnaces. I wasn't comfortable making the call on what we would do at the end of the service call and that was fine. There was no hard sell to make an option then and there. I really appreciated that.
After discussing it, my husband and I decided to replace the furnace with one of the options provided. We called the next day and they sent a couple of folks to replace it within a few days. The two gentleman were professional and thorough, and cleaned up everything before they left. They installed our Nest thermometer rather than the thermometer that came with the furnace, and everything has been working great.

"ABC Heating & Cooling does it again!...We spent the 1st summer in our newly renovated home miserable fron the great! So we decided before summer of 2020 rolls around we'd have seen air conditioning unit installed. Well it was a no brainer for us to reach out to ABC once again, since they had done such a great drop undertaking a heater in our rental property. Once again they came through and delivered great, professional service! They were on time, respectful of our home and patient while explaining how to use the unit. Big THANKS to Joaquin, Antonio and Ben for the great installation! Can't leave Jeff C. out for his salesmanship, expedited efficiency and competitive pricing to get the job done!! Look no further than ABC for all of your Heating and Cooling needs!!"

"Great! Tony called in advance & was very prompt. Personable and professional, he quickly hooked up his equipment and let the machines do their work, which took about 30 minutes for our 1400 SF house. He took photos of the intake duct so we could see their condition. I will be scheduling a manual deep cleaning of the whole system next!"

"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

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.
