Boiler Services

A boiler system uses hot water instead of forced air to keep your home warm and is one of the most energy-efficient heating options. Thanks to the thermal conductivity of water, a boiler will heat your home evenly and reliably, giving you great comfort all season long.

If your boiler is nearing the end of its life span or is starting to require frequent and costly repairs, it may be time for an upgrade. At A+ Derr, our experts are here to walk you through replacing your current boiler system, from selecting the right unit that meets your needs to providing superior installation services.

Don’t wait until your boiler fails and leaves you stuck without heat in the winter cold. Instead, consider upgrading today and experience these great benefits:

  • Greater energy efficiency
  • Improved heating power
  • Lower operating costs
  • Reduce risks of breakdown
  • Increase your home’s value

24/7 Boiler Repair

When your boiler is no longer operating at peak performance, trust the experts at A+ Derr to provide exceptional repair services. Our technicians have the knowledge and skills to quickly diagnose your boiler’s issue and complete the necessary repairs to get your heat back on in no time. If you’re experiencing any of the following, you may need repair:

  • Minimal heat: If you can’t get your house warm enough, regardless of the temperature on your thermostat, your boiler may have an issue that inhibits its ability to deliver heat throughout your home.
  • Unusual sounds or smells: Whistling or thumping signs indicate that your boiler has damage, whereas foul odors could mean a gas leak and serious danger.
  • Leaks: If you notice leaks from your boiler, this could be a sign of damage and may lead to increased energy usage or the risk of your boiler bursting.
  • Power cycling: If your boiler is frequently turning on and off, there is a good chance of an issue with the boiler’s power supply.

The average life span of a boiler is about 15 years. We recommend routine boiler maintenance to extend that life span and reduce the risk of breakdowns or costly repairs. Like every other element of your home comfort system, your boiler can benefit significantly from regular tune-ups. Our technicians will thoroughly inspect your system to ensure there are no issues and fix any minor problems before they become more serious.

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
