615 HVAC Questions, Answered Clearly

This is a Heco service-policy question. If Heco accepts the equipment type and brand, the advisor should say so; it should not refuse or promise coverage without checking the active service policy.

Brand coverage should come from the current Heco service policy and technician capability database. The advisor should ask for the brand/model when it could affect parts, warranty or serviceability.

Heco can diagnose only if company policy allows, but work by a different contractor may affect the original installer's labor warranty. The customer should review warranty terms before authorizing third-party repair.

Weekend or after-hours pricing is a company-specific fact. The Heco advisor must read the current approved fee schedule and never infer a surcharge from competitor practices.

Emergency-dispatch fees vary by contractor. Heco should answer only from current approved pricing and should separate any dispatch fee from repair pricing.

This should be handled by the booking system once Heco enables appointment changes. The advisor should verify the customer's appointment before changing it and follow the current cancellation/rescheduling policy.

Intermittent problems can still be investigated using symptom history, stored fault codes and measurements. If no fault can be confirmed, the technician should explain what was checked and what to monitor.

Arrival notifications should be controlled by Heco's communication settings and customer consent. The advisor should never promise a text notification unless that workflow is active.

A straightforward matched replacement is often completed in one workday, while duct, electrical, access or system-type changes can extend the project. Heco should give a project-specific schedule after evaluating the home.

A gas-to-electric heat-pump conversion can take longer than a like-for-like changeout because it may involve electrical work, air-handler changes, refrigerant piping, gas-line retirement and code verification.

A typical replacement includes protecting the work area, removing old equipment, installing the approved components, connecting refrigerant/electrical/drain/duct interfaces, startup testing and a customer walkthrough. The exact scope should be written before work begins.

It should be stated explicitly in the written scope. Heco's quote should identify removal/disposal, new equipment, labor, permits, testing and any excluded duct/electrical work rather than leaving those items assumed.

This is quote-specific. Heco should clearly show whether permit fees are included, estimated separately or customer-paid; the advisor should read the actual proposal rather than assume.

If the project requires HERS or other field verification, the proposal should state who arranges and pays for it. The requirement and cost can vary by project and jurisdiction.

Not automatically. Thermostat replacement depends on system compatibility, controls and the approved scope; the proposal should identify whether the existing control is reused or replaced.

Sometimes, but the furnace blower, indoor coil, controls, refrigerant compatibility and overall match should be evaluated. A partial replacement should still produce an approved matched system and required airflow.

Sometimes, but the new furnace must work with the existing indoor coil, blower/airflow needs, controls and venting. The equipment combination should be checked before assuming reuse is appropriate.

No. 'HVAC replacement' can mean different scopes depending on whether the home has a furnace/AC split, heat pump, packaged unit or other configuration. The proposal should name every component being replaced.

Often the indoor coil is part of the matched rated system. Reusing an old coil can create refrigerant, capacity, efficiency or compatibility problems, so the equipment match should be verified before deciding.

A matched system uses indoor and outdoor components that are tested or approved to operate together at specified capacity and efficiency. The exact combination matters more than simply matching brand names.

An AHRI certificate documents a tested combination of HVAC components and its rated performance. It can be useful for confirming matched efficiency and may be needed for incentive or code documentation.

Sometimes, if size, condition, cleanliness, routing and refrigerant/manufacturer requirements allow it. A replacement proposal should state whether the line set will be reused, cleaned, resized or replaced.

Replacement may be appropriate when the line is damaged, leaking, incorrectly sized, inaccessible to clean, contaminated or incompatible with the new equipment requirements.

Manufacturer procedures determine whether existing piping can be reused and what cleaning/preparation is required. This is not a one-rule-for-all-systems decision.

It may. Electrical requirements depend on the outdoor unit, air handler, auxiliary heat and existing service. Heco should compare equipment nameplate requirements with the home's electrical capacity before finalizing the design.

Not always. A load calculation on the electrical service should determine whether new HVAC circuits can be added safely or whether panel/service changes are needed.

The approved scope should address safe disconnection/capping of the gas branch serving removed equipment, subject to code and permit requirements. The customer should know whether gas remains for other appliances.

Not automatically. The existing ducts should be evaluated for required airflow, leakage and capacity; a heat-pump conversion can work with existing ducts when they are suitable.

Possibly, if it provides stable support, drainage, clearances and the dimensions required by the new unit and code. Replacement or extension may be needed for a different footprint.
