Tank and Tankless Water Heaters

We service and install all makes and models of tank and tankless gas and electric water heaters. Still trying to pick out the right system for your home? We’d be happy to talk you through it.

  • Tank water heaters, the classic way of heating water in a large tank so that it’s always available for usage, are reliable and hardworking. As long as they’re properly sized for your household, you should always have hot water when you need it.
  • Tankless water heaters solve a problem tank water heaters have: using up energy all day long when you only need hot water a few times throughout the day! Tankless water heaters work “on demand,” meaning water is only heated when you need it. This saves a lot of money throughout the year, though it may take a couple of minutes for the water to warm up.

Both systems have their benefits and their downsides. It all depends on what’s most important for your home and family. In any case, a high–efficiency water heater (tank or tankless) can help you to save money throughout the year and may qualify you for Xcel Energy rebates.

Your hot water heater is in good hands with Southwest Heating & Cooling. We have the experience and skill to diagnose problems quickly, find the most cost–effective solution, and carry out your water heater repairs. If it turns out you need a new water heater, we will make sure it’s a good fit for your home and help you find rebates (if applicable.)
