"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

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

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.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.
