Why Invest in Regular Tune-Ups?

When you invest in annual tune-ups, you benefit from:

  • Lower monthly utility bills. Heating and cooling tune-ups keep your systems more efficient, which lowers the amount of energy they need to run and reduces your energy costs.
  • Higher comfort levels. When your HVAC system is properly maintained, it can more precisely hit any temperature you want as well as provide proper dehumidification in the summer.
  • Increased system lifespan. Systems that are annually maintained typically live longer than those that are neglected.
  • Lowered risk of repairs/breakdowns. During a tune-up, we'll identify and fix small issues before they lead to major repairs and/or breakdowns
  • Keeping your manufacturer's warranty valid. Most manufacturers will automatically void your warranty if you can't prove that you've had your system regularly maintained by a professional.

    As a contractor myself, I’ve worked with Reliable on several projects in the past. Knowing their quality of work, when I needed work on my own home I knew who to call. Arrived on schedule. Diagnosed to problem and fixed it quickly. Travis was friendly and helpful and answered my questions. I would recommend them to anyone.

    When I called to request service they were able to send someone out that same day. When Edgar arrived he was polite and courteous. He explained what he was going to complete the diagnostics first. He then explained what needed to be done and made sure I understood. It was very appreciated that he gave me time to decide on my repair because it was going to cost a bit of money. He finished quickly and explained the invoice. Great job!

I will use you guys again in the near future!
