Signs You Need HVAC Service

As Tri-Cities homeowner, you know how important it is to keep your home comfortable throughout the year. Whether you’re staying cool during the hot summer months or keeping warm through the chilly winters, your HVAC system plays a critical role in your everyday comfort.

Here are a few signs that you need to have your HVAC system checked out:

  • Inconsistent temperatures: If certain rooms are warmer or cooler than others, your system may struggle to maintain airflow.
  • Unusual noises: Rattling, buzzing, or grinding sounds could indicate a mechanical issue that requires immediate attention.
  • High energy bills: A sudden increase in energy costs may mean your HVAC system is working harder than it should be, possibly due to inefficiency.
  • Foul odors: Unpleasant smells from your HVAC system can indicate mold, electrical issues, or debris buildup.
  • Age of the system:  If your system is 10+ years old and hasn’t been serviced recently, it may be time to consider an inspection or replacement.

Our HVAC Services

Our HVAC services are designed to make your life easier. We install top-of-the-line systems from trusted brands, including energy-efficient air conditioners, furnaces, heat pumps, and ductless mini-split systems—all engineered to handle the area’s hot summers and cold winters with ease.

Air Conditioning Services

Our highly trained technicians have the tools, experience, and knowledge to tackle your toughest air conditioning challenges.

Our services include:

  • Air conditioning repair: Prompt repairs help prevent further damage, extend the life of your system, and keep your home comfortable during the hottest months
  • Air conditioning installation & replacement: Our installation process is thorough, starting with a consultation to assess your needs, followed by expert installation and a thorough system check to ensure optimal performance.
  • Air conditioning maintenance: It’s best to schedule maintenance before the summer heat arrives, ideally in the spring, to ensure your system is ready for the warmer months.

Heating Services

Tennessee winters can be harsh, with temperatures frequently dropping below freezing. A dependable heating system is key to keeping your home cozy and comfortable through those cold, frosty days and nights—and we’re here to help.

Our services include:

  • Heating repair: Common heating repairs include fixing things like broken thermostats, clogged filters, or blower issues.
  • Heating installation and replacement: If your heating system is over 15 years old, needs constant repairs, or is not keeping your home warm like it used to, it might be time to replace it.
  • Heating maintenance: The best time to schedule heating maintenance is in the fall before the cold weather hits, so your system is all set for winter.

Indoor air quality services

Indoor air can be 2 to 5 times more polluted than outdoor air. At Stateline Services, we offer solutions to improve the air quality in your Tri-Cities or Southwest Virginia home. We’ve got you covered, from humidifiers that balance moisture levels to air purifiers and cleaners that tackle dust and allergens.
