We recommend professional HVAC maintenance at least once per year, ideally twice (spring and fall). This ensures your heating system is ready for winter and your cooling system is ready for summer. More frequent maintenance is beneficial for older systems or those in high-use situations.
Maintenance is preventive service performed on a functioning system to keep it running well. Repair is corrective work done when something has already broken. Maintenance is always less expensive than repair, and it prevents most repairs from being needed in the first place.
You can perform basic tasks like changing filters monthly and keeping vents clear. However, professional maintenance requires specialized tools and expertise. Refrigerant handling, electrical testing, and system diagnostics must be performed by certified technicians. DIY attempts can actually damage your system or void your warranty.
A single maintenance visit typically ranges from $100-$200, depending on your system type and any issues discovered. Bi-annual maintenance costs around $200-$400 per year. This investment pays for itself through energy savings and prevented emergency repairs within the first year.
Our technician will inspect your entire system, clean components, test controls, check refrigerant levels (if applicable), lubricate moving parts, and test system performance. We’ll explain what we find, answer your questions, and discuss any recommended repairs or upgrades. The appointment typically takes 1-2 hours.
Yes. We work 365 days a year, including holidays. Your family’s comfort doesn’t stop for holidays, and neither do we.
No maintenance plan prevents all possible issues, but regular professional service prevents the vast majority of problems. Some component failures are simply age-related and can’t be prevented, only prolonged. Our goal is to catch issues early and keep your system running as long as possible.
Yes. Maintenance contracts typically offer discounted service rates, priority scheduling, and sometimes additional benefits like extended warranties or discounts on repairs. If you commit to regular maintenance, a contract usually saves you 10-15% compared to pay-as-you-go service.
Don’t let a broken HVAC system ruin your comfort. Whether it’s an emergency repair at 3 a.m. or a diagnostic visit during the day, we’re ready to help.
