"There was very little work to do. They came out on time and I was happy for the professionalism, but there was nothing to do because it's a brand new system. The service is free for a year. I could have had them come out in April to check the air conditioning system, but since they just installed the unit in April, I didn't bother, but it would have been free. This fall, when I called him to check the furnace, he thought he was coming out to check the air conditioning, I said, "no, you're here to check the furnace because I'm going to be using the heat this fall". He said, "no problem" and he checked that out, he said, "I feel like I'm not doing anything, I can still check the air conditioner", and I said, "if you want to, but I've been running it all summer and it's been great". I asked him there was a charge and he said, "no, the first year was free"."

"I called Mr Parham and he responded very promptly. When he arrived he was very professional. He gave me a very reasonable estimate on the cost to have the compressor replaced. The parts were ordered and installed as promised. I have also used him to have the thermostat replaced in my refrigerator. My washer was leaking water, he also fixed that also. All these were separate house calls, and each time Mr Parham was also professional, and on time and did the work as promised."

"Jason Johnston and his staff were, and always have been, professional, more than competent and trustworthy! We had a major issue with the installation of our wood burning furnace by another local company, as well as that same company completely messing up our heat pump. We were left flat with a tremendous mess on our hands. I found Johnston's company and he came in and actually took the time to look over the specs for the system and worked with us to get it straight. We have had to have him return for that system several times, for things that were our fault not his, and he has always been prompt, attentive to our concerns and fair and honest in his dealings with us. We highly recommend you consider hiring this company for your HVAC needs."

"Anthony came to our house on Sunday to check our heating system and discovered the inside was completely rusted out . We discussed our options and had a new high efficiency system installed the next day and we couldn’t be happier. If we have any problems in the future we won’t hesitate to call them again."

Install Boiler FAQs, answered by experts

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

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.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

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.
