  • How frequently should I replace my air filter?

    We recommend changing your air filter every 60 to 90 days for most homes. However, replacing it every 30 days is ideal if you have pets, allergies, or live in a dusty area. A clean filter improves air quality, boosts system efficiency, and helps extend the life of your HVAC equipment. Regular checks make it easier to catch buildup early and avoid restricted airflow or strain on the system.

  • How regularly should my HVAC system be serviced?

    We recommend having your HVAC system professionally serviced twice a year—once before cooling season in spring and again before heating season in fall. Routine tune-ups help identify issues early, keep the system running smoothly, and improve efficiency. Regular maintenance also helps reduce the risk of breakdowns, saves energy, and ensures your home stays comfortable year-round.

  • What is the typical lifespan of an HVAC system?

    A well-maintained HVAC system typically lasts 12 to 15 years, though some systems can operate longer with proper care. Factors like usage, maintenance frequency, and equipment quality all play a role in longevity. Annual service, prompt repairs, and changing filters regularly can help you get the most out of your system. When your system starts needing frequent repairs or struggles to maintain comfort, it may be time to consider a replacement.

  • At what point is payment required for service?

    Payment is generally due when the service is completed, unless prior billing arrangements are made. For system replacements or larger projects, we offer clear estimates and may provide financing options or split payments. We accept several forms of payment, and you’ll receive a full breakdown of costs before the work is finalized. Our goal is to keep the process simple, transparent, and convenient.

Matt was fabulous!! He absolutely knows what he’s talking about and gave us a fair and honest pricing. I loved that he took the time to figure out what system would work best for us and then gave us a plan for how to get AC into our house without breaking the bank. We had a different company quote us twice the amount for the same services. Highly recommend you give him a call!

Matt was amazing. He responded quickly and fix our A/C unit that was a disaster. We had multiple people out to look at it and Matt would not give up and got it going. We have had no issues since he came out.

We bought our home15 years ago. Over the years Matt has worked on and when needed replaced our heating and air and water heater. When it was fixable he repaired it. Not once has he tried to sell us something we didn't need. We have always been very satisfied with his work. Matt is reliable and honest.
