"As a small business owner, I strongly caution others against this HVAC/R company. In over 10 years, they?ve been the least trustworthy and poorest performing contractor I?ve worked with. We experienced repeated service issues, a 25% rate hike without notice, ignored emails, and unreturned quote requests. Worse, we were billed for work that wasn?t done?confirmed twice, including by a third-party inspection with photos. Even when confronted, they deflected and delayed for months. We had to hire another company. They also mis-sized a walk-in freezer due to bad measurements and blamed their supplier. When shown proof it was undersized, they argued with no solution. They later mismeasured again on a replacement bid. Their attitude throughout was defensive, unprofessional, and dismissive. If something goes wrong?and it likely will?they will not stand behind their work. Save yourself the frustration and look elsewhere."

Gas Leak Repair questions, answered by experts

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.

In most cases, yes, it’s safe to light a gas water heater manually, but you should shut the gas off first, open a window, and let the space air out for about 10 minutes. Modern water heaters shut the gas off entirely if the pilot light goes out, but airing out the area beforehand is good practice and will ensure it’s safe to relight your pilot light manually. Just make sure you turn the gas valve to “pilot” before lighting. If the light keeps going out or won’t light at all, call in a professional.

Yes, it’s possible to convert an oil furnace to gas. However, you may have to replace the furnace completely instead of simply converting it. If the original oil furnace has had any type of damage or is older (typically considered over 15 years old), then you will likely need a full replacement versus a conversion.

Some natural gas furnaces can be converted to propane with a conversion kit, but not all models are compatible. Consult a licensed HVAC pro to determine if conversion is possible and cost-effective for your system. The process involves changes to burner orifices and safety controls, and must be completed to code.

Many people find switching from an electric stove to a gas stove well worth the hassle. After all, gas stoves last up to 15 years, whereas most electric stoves only last up to 13 years. Plus, the sentiment and joy of cooking over a real fire is indeed irreplaceable—and offers more precise temperature controls than electric cooktops. The cost of converting an electric cooktop to a gas stove depends on whether your kitchen already has gas supplies, and the cost can range from $125 to $2,000. Also, make sure your new stove’s dimensions match the old one.
