"We were very happy with Bama Air Systems. They came out for an estimate on a Mini-Split in a timely manner, and had a quick turn-around time for installation. Their service professionals, Austin, Zach and JC, were on time, friendly and courteous, and very efficient. The installation took less than a day, and they cleaned up the construction debris thoroughly. We would definitely recommend them for your HVAC needs."

"Mr. Coffee is a hero who risks his health daily to help mitigate dangerous radon problems for strangers who call for help. This is a dangerous job with daily high radon exposure and when I asked, he said he is aware of the risks but gets his health scanned multiple times a year. I called Covenant Air back in December after noticing that my Safety Siren Pro radon detector kept reaching alarm. Mr. Coffee came out and assessed that I could probably fix the problem myself by sealing some obvious cracks, especially around some pipes, and recommended the products so that I can do it cheap DIY. He was obviously not pushy to scare people into signing contracts, but actually tried to dissuade me from hiring him right off on installing sub slab depressurization. Although the DYI route he recommended would've been cheaper, I hired him to performs the job. The sealing did bring the radon level down where my detector's alarm didn't go off, but I wanted to lower it as much as possible. He then recommended a passive ventilation route given my reading. The passive ventilation again slashed the radon level in half, but I wanted the radon level down even further, so I ultimately opted to install the fan after weeks of data collection and analysis. He installed the fan so that I could easily turn it off to save energy based on seasonal variations. He is a very personable and methodical person, and prefers to monitor the progress of his work so that his customers don't hastily incur unnecessary cost. You almost never see someone like that in the service industry, and I cannot recommend him highly enough.

Install Boiler FAQs, 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.

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.

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.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

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.
