"We called first thing in the morning because our refrigerator had turned off due to problems with our electrical panel. They worked us in and showed up within the hour to fix the problems. Extremely professional, kind, and knowledgeable. Will definitely use them again in the future for any electrical, a/c, or plumbing needs."

"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."

"I have been using Ethridge for at least 12 years. We have a maintenance contract with them so I see their technicians at least twice a year and it has been the same knowledgeable guys every time. When Daniel said last Friday that my heat pump was going out I knew they were the only ones I would trust to do the job so I did not think about trying to get a cheaper price elsewhere. My confidence in them increased when the same lead installer arrived at my house to do the job who had been at my house probably 5 years ago to install a thermastat. Daniel had forwarned Billie my job was not going to be easy because the old heat pump to be replaced was in the attic. Billie came in with the most positive attitude and he had remembered being at my house. They stayed late to finish the job up. When they left he and his team left everything clean. I could not have ask for a more competent crew to do this job. I highly recommend this company."

"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

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

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.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
