"Luckily our heater waited for us to wake up on a Friday morning before conking out. I thought we might be able to make it through the weekend, but when it looked like that wasn't going to happen, they had someone out later that day for us. Fixed the heater, kept the costs down. I could only imagine al the things it _could_ have been. So impressed we signed upt for their regular maintenance plan right there.

"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."

Install Boiler FAQs, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

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.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
