"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left."

"Michael offered great advice on where to place our new tankless heater and his team did a great job executing. There were a few hiccups that came with replacing the old tank heater and working with the old plumbing of the home, but Jax Mechanical were able to solve any problems that popped up. Michael was also proactive in the initial discussion and found that our PRV needed replacing which was something we were glad he found before it led to any long term issues."

"It went extremely well!! The technician was courteous, knowledgeable, professional, and did a fantastic job. In the 12 years that we have owned our home, I can honestly say that Water Heaters Only is the BEST company we have dealt with in having repairs done. It’s too bad they only work on water heaters."

"Repair was done on my daughter's car who is in college in California, I live in Colorado. The owner spoke with me on the phone prior to doing the repair to explain issues with car. His assessment was consistent with the problems my daughter described to me. The price was very reasonable for all the parts and labor. The job was completed quickly and they stayed past closing until my daughter could get there to pick up car. They accepted my payment over the phone and offered to check her fluids and inspect car periodically in the future for free. I think you will be very satisfied using this garage as this and other reviews have clearly shown.

"⭐⭐⭐⭐⭐ Exceptional Service from Airtime Plumbing, Heating, & Air! I cannot recommend Airtime Plumbing, Heating, & Air highly enough! From the initial service call to the completion of the job, my experience was absolutely five-star. We had an urgent issue with our furnace acting up just as the cold weather hit, and they responded with incredible speed and professionalism. The technician David arrived promptly, was extremely courteous, and clearly explained what was wrong with our unit. He didn't just fix the problem; he took the time to show me what maintenance steps I could take to keep the system running efficiently. What Made Them Stand Out: Punctuality & Communication: They called ahead, arrived exactly when they said they would, and kept me informed throughout the process. Expert Knowledge: The diagnosis was fast and accurate. They fixed the problem right the first time. Fair Pricing: The final cost was competitive and exactly what was quoted, with no hidden fees or upselling. Cle"

"Ryan, the owner from Airtight A/C came right over and fixed our unit asap just before the big heat! He was in and out within the hour..no muss, no fuss and his prices were lower than other places we called in our area. He will be our "go to" technician in future calls for heating and cooling problems. Great, quick service. Five stars easy! Thanks a million Ryan. You saved our lives in this heat! Joe & Alice Skiles"

Boiler Repair FAQs, answered by experts

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

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

There are a couple of signs that will tell you it’s time to bleed the radiator. If the radiator is making noises, it’s typically because of trapped air, which you can release by bleeding the radiator. You can also test the radiator by turning on your heat and then placing your hand near the top and bottom of the radiator. If you feel cold spots, particularly at the top of the radiator, it’s time to bleed it.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

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.
