"Maynor has taken care of our HVAC needs for years and we are very happy with them. When our unit was in need of replacement Mike Langdon thoroughly evaluated our upstairs space to assess the type of HVAC unit we would need. They were able to install it the next day. Installers Devan and Beiri were professional, kind, prompt and efficient and kept us updated throughout the installation. Our experience with Maynor has always been 5 stars."

"My prior water heater, a 50-gallon tank, started leaking after 15 years. I called Streamline to confirm that it needed replacement, and to replace it. I was considering a tankless water heater already, and the first tech walked me through the pros and cons, then wrote up an estimate. Two additional techs came the next day to install the heater and the necessary gas and power lines. The only issue I had was that one of the newly installed gas fittings leaked gas into the basement. I shut off the supply valve and called Streamline, and they came out within half an hour to fix it at their expense. Mistakes happen, and I was impressed with how professionally they corrected that one."

"Carolina Comfort installed a new HVAC system at our home. They did a great job from the original recommendation on the type of unit- a ducted split system- to a quick scheduling of the work- and lastly installing the system. Ryan, Dylan and John were great- very polite and professional and got the system and fully installed and running within the time frame promised. Would definitely use them again."

"Our motor burned out the week before Christmas during the night. I called Alpine and the serviceman was at our home the next morning.
He determined the problem, let us know the cost and the part was ordered immediately. He installed the part as soon as it came in. We have been standing customers with Alpine and the prior HVAC company with a service plan. We appreciated their responsiveness and flexibility. R Hall Durham

Install Boiler questions, answered by experts

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

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.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
