"Wahl was able to provide same-day service on my furnace that had shut off in the midst of our first snowfall this year. Within 2 hours of arriving, they diagnosed and fixed the issue. They recommended replacement options in the next year, but weren't pushy about me spending that type of money now, which I appreciate. I'd recommend their expert, timely team to anyone!"

"The installers were punctual. They were very professional and friendly. They cleaned everything up before they left. There was no mess. I was very satisfied with the whole process. It's only been a few weeks since the installation so I am not able to comment on the longevity of how the units run over years or the service department."

"I met with 2 or 3 reputable companies in addition to Wade prior to selecting Carrier and Wade for the job. The choice was an easy one. It began with Lonnie, Wade's sales rep. There was no pressure or hype with Lonnie. His communication skills are excellent. Over the course of our discussions, Lonnie prepared several revised proposals at my request as I honed in on what I wanted. Unlike any of the other bidders, Lonnie's proposals were very detailed with costs broken out for various components of the job. I knew exactly what I was buying, both in terms of equipment and services. Lonnie worked with me to reach a fair price. At my request, Lonnie coordinated directly with Air Duct Maintenance so the ducts were cleaned the day prior to the removal of the old furnace and installation of the new. The actual installation was done by Wade installer Ryan, with assistance from Dillon. You will not find a more professional or competent installer than Ryan. During the 2 days that he and Dillon were here, I happened to be working on a project on the same floor as the furnace. In those 2 days, I actually can't recall Ryan ever having a conversation about any topic other than my installation. He was laser focused on my installation. As part of his job, Dillon installed a new pad for the AC compressor. Every aspect of the job was done carefully and neatly. Following the installation, Ryan walked me through use of the new thermostat. He took his time, did not rush me through it and made sure I was satisfied. Finally, every one I have spoken with over the phone at Wade HQ has been friendly, accommodating and followed through when they said they would. If you are replacing your heating and cooling system, I would encourage you to consider Wade H&C. I'm glad I did."

"When our pipes leaked, it was a really bad time. A lot of people in West Virginia had frozen pipes because there was a bad storm. There was at least 20 or 30 before us so they worked them, and they got to us in a day and a half. Considering what they had ahead of them, we know they must have worked overnight."

"Great. I called because furnance stopped working. Brian responded quickly and showed me exactly what was wrong. Because it was a crack in the heat exchanger, the furnance had to be replaced, Brian was very knowledgable and explained exactly the options. He quickly got everything needed to repair and up and running, I was only without heat for 1 day, I would recommend him to anyone who needs Heating or AC repairs and installs."

Install Boiler FAQs, answered by experts

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

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.
