"Kelly’s AC was awesome! They got a new AC unit installed for us super fast and charged a really fair price. The guys showed up on time, did clean work, and didn't leave any mess behind. ​Honestly hard to find honest people who work fast and don't charge an arm and a leg. If you need any AC work done, definitely give them a call!"

"It went fine.  No problems reported.
Southbelt did not offer Angie's list discount.  And service from other competitors would have been less expensive.  But Southbelt installed my full AC / heating system.  So, I stayed with them.

"DAVID HAD TO RAISE AND RE-HANG THE HVAC UNIT FROM THE RAFTERS OF THE HOME AS IT WAS INITIALLY INSTALLED IMPROPERLY.  THE UNIT NOW DRAINS PROPERLY INTO THE PLUMBING SYSTEM.  HE ALSO DISCOVERED A FAULTY HEAT LIMITING SWITCH ON THE FURNACE - NOT A MINOR ISSUE - AND REPLACED IT AND TESTED THE SYSTEM.  FINAL COST WAS MUCH LESS THAN HIS INITIAL ESTIMATE.   DAVID IS ALWAYS ON TIME, VERY POLITE, VERY KNOWLEDGEABLE AND PROFESSIONAL ABOUT HVAC SYSTEMS, AND VERY REASONABLE IN HIS PRICING.  I SIMPLY WON'T USE ANYONE ELSE FOR MY HVAC NEEDS AS THIS COMPANY IS SIMPLY THE BEST.

"Very well.  I have an old unit that is probably close to going out completely.  I called Chris on a Thursday, after 7:00 PM and coming home to an A/C unit that was blowing hot air.  I found Cucco's through another provider search company but I am glad I found him.  Other providers I have used in the past when I had a home warranty were not nearly as attentive, responsive, willing to answer to answer my questions, or as courteous - in fact, some of them were just down right rude! That was not the case with Chris. He went out of his way to explain his process and assure me that he was doing everything possible to ensure my A/C unit was being repaired to the best of his ability.  He even explained how my unit is not up to code, what it will take to get it up to code, and how to avoid costly repairs in the future. I will definitely call Chris again when the time comes to replace my unit and bring it up to code!

Install Boiler FAQs, answered by experts

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

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.
