I had a very positive experience
I had a very positive experience using HVAC technician Quenton Martel from David Gray. He was professional, easygoing, provided great education about what he was doing and what his recommendations were, and was a really nice technician to work with. I highly recommend both this company and this technician when needed. Great job, thank you!

Your Questions, Answered
  • What should I do before calling for repair?
    Before calling for repair, check your thermostat settings and ensure your filters are clean. Make sure the system has power and there are no tripped breakers. If issues persist, contact our team. Providing these details helps us diagnose the problem faster.
  • How often should I have my HVAC serviced?
    Maintenance is key for efficiency and longevity. We recommend having your HVAC system serviced at least once a year, ideally before the peak seasons of summer and winter. Regular maintenance can help identify problems early and improve system performance.
  • What are the signs my HVAC needs repair?
    Common indicators include unusual noises, inconsistent temperatures, foul odors, and higher energy bills. If you notice any of these signs, it may be time to schedule a repair service to prevent further damage to your system.
  • Can I perform HVAC repairs myself?
    While there are some basic maintenance tasks you can perform, such as changing filters, it's best to leave repairs to professionals. HVAC systems are complex, and improper handling can lead to further damage or safety risks. Our trained technicians ensure repairs are done safely and effectively.
