"The smallest bedroom in my house has been the coldest in the winter and the warmest in the summer for years. I have had three much larger companies take a look at my ducts and my A/C system to find out what the problem was. Each one said the system was old and weak and that was just the way the house was made. The system was very old and I decided to replace it because it was leaking Freon. Darryl’s installation cost for a new system was almost half of what those larger companies I used before was. His installation techs were very professional, polite, and very diligent workers. The company has many different payment options that I feel would accommodate almost anyone. Finally, I told Darryl about the issue with the small bedroom. Within minutes he came up with a simple solution to get more air into the bedroom. The cost to solve the issue was very reasonable. A week later, the repair was completed. The problem was solved, and my daughter loves me even more now. I highly recommend Darryl’s Heating and Air and will only be using them from here on out for all my heating and air needs."

Boiler Repair questions, answered by experts

Modern boilers average around 20 years of use before failing, with some hitting 25 to 30 years. Older boilers, however, can last up to 50 years because they are often made from ultra-durable cast iron. Newer models are made from steel alloy and related components, which are great for withstanding high pressure levels and hot temperatures but offer a slightly lower life span.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

In most cases, it’s worth it to repair a radiator that isn’t functioning properly. Provided you’ve ruled out any underlying issues with your boiler or circulating pumps, problems with radiators are typically easy for a professional to diagnose and fix. In most cases, your heating radiator repair won’t cost you more than $100 to $200, which pales in comparison to the cost to replace a radiator, an average of $1,500. It’s best to call in a professional to see which solution is ideal for your situation.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
