Frequently asked questions
What is included in your maintenance services?
OTTER Basic Maintenance covers a full seasonal inspection: thermostat, electrical connections, refrigerant level, capacitor, contactor, condenser fan motor, and more. OTTER-Pro includes everything in Basic plus deep cleaning of accessible components, air filter replacement, and combustion analysis.
How often should I service my system?
We recommend seasonal maintenance, at minimum once a year. Our OTTER Basic plan ($250/unit) covers essential seasonal care, and OTTER-Pro ($350/unit) adds deep cleaning, filter replacement, and combustion analysis for more complete protection.
Are cheap tune-up offers worth it?
Some services such as duct cleaning, maintenance plans, or accessory installations may be beneficial in certain cases, but should always be evaluated based on actual system condition, not assumptions. Quality maintenance takes proper time — unrealistically low pricing usually means a sales visit, not a service visit.
