# Homeowner guides for Magna

- [Before the HVAC installer leaves: a useful handover checklist](https://localfoundryhq.com/guides/hvac-installation-handover-checklist): Collect equipment models, operating instructions, commissioning information, permit records and warranty responsibilities. A finished-looking installation is not the same as a documented handover.
- [A new HVAC noise: describe the sequence, not a guessed part](https://localfoundryhq.com/guides/new-hvac-noise-how-to-describe-it): Record when the noise occurs, where it is heard and whether comfort or operation changed. A safe recording can help service intake, but sound alone does not identify a failed component.
- [Water near the indoor AC unit: what to report](https://localfoundryhq.com/guides/water-near-air-conditioner-indoor-unit): Record where water first appears, whether it coincides with cooling and what equipment or finishes are nearby. Condensate-related issues need assessment; do not assume every puddle has the same source.
- [Before buying an HVAC maintenance plan, read the visit scope](https://localfoundryhq.com/guides/hvac-maintenance-plan-what-is-included): Compare the actual inspection and maintenance tasks, scheduling, exclusions and renewal terms. A membership label or priority-service promise does not define what will happen during a visit.
- [Compare HVAC estimates by the installed result](https://localfoundryhq.com/guides/compare-hvac-installation-estimates): Match equipment, design assumptions, duct and electrical work, controls, permits and commissioning before comparing HVAC totals. A model number and price alone leave important scope questions unanswered.
- [Why HVAC sizing should start with the home](https://localfoundryhq.com/guides/hvac-sizing-bigger-is-not-always-better): Ask how the contractor assessed the home’s heating and cooling loads, distribution and planned changes. Reusing the old unit’s size or choosing a larger one is not a complete design method.
- [HVAC repair or replacement: build an evidence-based comparison](https://localfoundryhq.com/guides/hvac-repair-or-replacement-decision): Use the diagnosis, recurrence, comfort, design and full installed scope to compare options. Equipment age is useful planning information, not a stand-alone order to replace a system.
- [Smart thermostat upgrade: check compatibility before buying](https://localfoundryhq.com/guides/smart-thermostat-compatibility-questions): Confirm equipment type, supported controls, wiring requirements and the functions you want to retain. A popular thermostat is not automatically compatible with every furnace or heat pump.
- [Before buying indoor-air upgrades, identify the source](https://localfoundryhq.com/guides/indoor-air-quality-upgrades-questions): Start with the pollutant or moisture concern, then compare source control, ventilation and filtration. No single air-cleaning product removes every indoor pollutant.
- [Duct cleaning and duct sealing solve different problems](https://localfoundryhq.com/guides/duct-cleaning-or-duct-sealing): Cleaning addresses material in ducts; sealing addresses unwanted air leakage. Ask what evidence supports either service, and do not treat dust alone as proof that a whole duct system needs work.
- [Planning a ductless mini-split: room layout matters](https://localfoundryhq.com/guides/ductless-mini-split-planning): A mini-split proposal should explain which rooms are served, how air reaches them, where equipment and drains go and how the system will be maintained. One indoor unit is not automatically a whole-home design.
- [Heat pump, furnace or dual fuel: compare the whole proposal](https://localfoundryhq.com/guides/heat-pump-or-furnace-compare-proposals): Compare the home’s needs, distribution, electrical and fuel infrastructure, controls and installation scope. A technology label alone does not establish comfort or operating cost at your property.
- [Considering a heat pump in cold weather? Ask these design questions](https://localfoundryhq.com/guides/heat-pump-cold-weather-questions): Ask for heating performance at relevant outdoor conditions, a property-based load assessment and an explicit backup-heat strategy. A cold-climate label helps identify products; it does not design the installation.
- [Choose an HVAC filter that fits the system—not just the shelf](https://localfoundryhq.com/guides/choose-the-right-hvac-filter): Match dimensions, manufacturer requirements and airflow capability before choosing a higher-rated filter. More filtration is not useful if the system cannot accommodate the product correctly.
- [Why some rooms stay too hot or too cold: a better assessment plan](https://localfoundryhq.com/guides/some-rooms-too-hot-or-too-cold): Uneven comfort can involve airflow, controls or the building itself. Map the rooms and timing before assuming a larger heating or cooling unit is the answer.
- [Heating or cooling starts and stops quickly: what to record](https://localfoundryhq.com/guides/hvac-short-cycling-what-to-record): Frequent short cycles are worth reporting, but their cause cannot be inferred from timing alone. Record conditions, whether comfort is maintained and recent changes before approving controls or equipment work.
- [Furnace will not start: what to record before calling](https://localfoundryhq.com/guides/furnace-will-not-start-service-checklist): For a no-heat enquiry, provide the model, visible code, thermostat behavior and recent changes. Keep combustion and electrical work with qualified service, and handle alarms or gas concerns through emergency channels.
- [AC running but not cooling: prepare a useful diagnostic visit](https://localfoundryhq.com/guides/air-conditioner-running-not-cooling): Record thermostat settings, affected rooms and when cooling changed. Basic observations can help a technician, but a running fan does not prove the refrigeration system is working correctly.
- [10 furnace changes worth reporting before a breakdown](https://localfoundryhq.com/guides/ten-signs-furnace-needs-attention): An unfamiliar furnace pattern deserves a clear service report. Separate routine comfort changes from urgent hazards; a carbon monoxide alarm or suspected gas leak is not a routine troubleshooting task.
- [10 signs your air conditioner deserves a service assessment](https://localfoundryhq.com/guides/ten-signs-air-conditioner-needs-attention): Longer run times, weaker cooling or a new sound are reasons to investigate, not proof that an AC needs replacement. Record the change and the conditions so the technician can test the actual problem.
- [Before you book an HVAC maintenance visit](https://localfoundryhq.com/guides/prepare-for-hvac-maintenance): Turn a vague tune-up request into a clear conversation about your equipment, comfort concerns, service history and the proposed maintenance scope.
- [One home project, several trades: make the handoffs clear](https://localfoundryhq.com/guides/plan-connected-home-service-work): Organize a project involving plumbing, HVAC and electrical work by agreeing on equipment details, scope boundaries, approvals and who coordinates the next step.
- [Five details that make a service callback more useful](https://localfoundryhq.com/guides/prepare-for-a-service-callback): Prepare your property city, service need, symptom history, callback number and access notes so the first conversation can move the request forward.
- [Compare the scope, not just the number at the bottom](https://localfoundryhq.com/guides/compare-home-service-estimates): A practical way to compare home-service estimates: separate diagnosis, repair scope, materials, scheduling and approvals before choosing a provider.
