HVAC FAQs
- How often should I service my HVAC system in North Texas?
- HVAC systems in North Texas should be serviced twice a year — once before the summer cooling season (typically March–April) and once before the winter heating season (October–November). The extreme summer heat puts significant stress on air conditioning systems, making pre-season tune-ups essential to avoid breakdowns during peak demand periods.
- What does HVAC maintenance typically cost in DFW?
- A standard HVAC tune-up or maintenance visit in the DFW area typically costs $75–$150 per system. Many contractors offer annual maintenance agreements for $150–$300 that include two visits per year and discounts on parts and labor. Emergency service calls, particularly during summer, often carry additional fees of $50–$100 or more.
- When should I replace my HVAC system?
- HVAC systems typically last 12–15 years in North Texas conditions. Signs that replacement may be needed include the system requiring frequent repairs, difficulty maintaining target temperatures, significantly higher utility bills, the system using R-22 refrigerant (phased out in 2020), or the unit being more than 15 years old. Getting multiple quotes is recommended as HVAC replacement is a significant investment.
- What size HVAC system do I need for my North Texas home?
- HVAC system sizing depends on your home's square footage, insulation quality, number of windows, ceiling height, and local climate factors. A licensed HVAC contractor will perform a Manual J load calculation to determine the correct system size. Oversizing is a common mistake that leads to short cycling and poor humidity control, so proper sizing is critical in the humid North Texas climate.
- How do I find a reputable HVAC contractor in North Texas?
- Look for HVAC contractors who are licensed by the Texas Department of Licensing and Regulation (TDLR), carry proper insurance, have NATE-certified technicians, and have verifiable reviews on Google, Yelp, or Angi. Get at least three quotes for major work, and be cautious of contractors who quote over the phone without inspecting your system.
