Service overview
What this service covers
Upgrade to variable-speed equipment for steadier comfort and efficient operation. For homes, businesses, and managed properties, the useful scope depends on the installed equipment and the conditions present at the property. Air-conditioning diagnostics connect the thermostat call, indoor airflow, coils, condensate, electrical starting components, refrigerant operation, and outdoor heat rejection.
Replacement work should not be treated as a nameplate-only swap. The existing system, building load, distribution, controls, electrical or fuel readiness, access, efficiency goals, and compatible equipment combinations all influence the recommended scope and final commissioning steps.
- Document cycle behavior, thermostat settings, indoor conditions, and when the symptom occurs
- Review filter condition, return and supply airflow, and accessible indoor and outdoor coils
- Inspect condensate, controls, safeties, contactors, capacitors, motors, and wiring as applicable
- Evaluate refrigerant operation through qualified diagnostic procedures when indicated
- Run the system through a completed cooling cycle after approved work
- Document why the existing equipment is being replaced and any unresolved distribution or control issues
- Compare capacity, efficiency, compatibility, installation constraints, and future service access

In an industry that often fraught with contractors taking advantage of homeowners, Andrey was honest with his assessment and willing to install a product acquired elsewhere (most want that margin themselves), patiently answered my questions (I’m an engineer so like to understand what’s happening), and proactively offered practical...
