Frequently Asked Questions

HVAC maintenance should be scheduled bi-annually—once before cooling season and once before heating season. Regular inspections help prevent emergency breakdowns, improve energy efficiency, and extend your system's lifespan. At Onetech heating and air, our maintenance plans include thorough cleaning, advanced diagnostics, and priority scheduling for Sherman, TX homeowners.

A comprehensive residential HVAC system check includes inspecting air filters, testing thermostat accuracy, checking refrigerant levels, cleaning condenser coils, and evaluating airflow. Technicians also examine electrical connections and identify potential issues before they become costly repairs. These checks ensure your system operates efficiently year-round in Sherman's variable climate.

Replace your HVAC system if it's over 15 years old, requires frequent repairs, or has diminishing efficiency that drives up energy bills. A new installation often pays for itself through lower utility costs and improved comfort. At Onetech heating and air, certified technicians perform comprehensive post-installation testing to ensure optimal performance.

Commercial HVAC installation costs depend on building size, system complexity, ductwork requirements, and equipment selection. Larger facilities or multi-zone systems require more extensive design and installation work. Proper system sizing and professional design minimize long-term operating costs and reduce downtime for Sherman, TX businesses.

Emergency HVAC repairs typically begin within hours of your call, with many common issues resolved the same day. Rapid response times are critical during extreme weather when heating or cooling system failures affect comfort and safety. Onetech heating and air offers 24/7 emergency services for both residential and commercial properties in Sherman, TX.

Furnaces generate heat by burning fuel or using electric resistance, while heat pumps transfer existing heat from outdoor air. Heat pumps are more energy-efficient in mild climates but may struggle during extreme cold. Sherman, TX winters are generally mild enough for heat pumps to perform effectively with proper maintenance and sizing.

HVAC maintenance plans reduce long-term costs by preventing expensive emergency repairs, extending equipment lifespan, and improving energy efficiency. Plans typically include bi-annual inspections, priority scheduling, and repair discounts. At Onetech heating and air, maintenance plan members receive advanced diagnostics that catch small problems before they escalate.

Sherman's hot, humid summers place heavy demand on air conditioning systems, requiring regular maintenance to handle extended run times. High temperatures can strain compressors and refrigerant levels, while humidity affects indoor air quality. Properly maintained AC systems with clean filters and adequate refrigerant perform more reliably during Texas heat waves.

The biggest mistake is neglecting routine maintenance until a system fails, often during extreme weather when repairs are most urgent and costly. Skipping bi-annual inspections allows minor issues to worsen, reduces efficiency, and shortens equipment life. Preventative maintenance catches problems early and keeps systems running reliably year-round.

HVAC systems can be installed in older buildings, though they may require custom ductwork design, electrical upgrades, or creative equipment placement. Professional assessment identifies structural considerations and ensures proper airflow and efficiency. At Onetech heating and air, certified technicians design tailored solutions for both residential and commercial properties throughout Sherman, TX.

Before HVAC installation, clear the work area around existing equipment, ensure access to electrical panels, and communicate any home layout concerns to technicians. Professional installers handle system removal, ductwork modifications, and equipment placement. Comprehensive post-installation testing verifies proper operation, airflow, and thermostat functionality before completion.

Commercial HVAC systems are larger, more complex, and operate longer hours than residential units, requiring specialized maintenance and faster emergency response. Businesses need minimal downtime to avoid productivity loss and customer discomfort. Tailored commercial solutions account for building size, occupancy patterns, and specific climate control needs across multiple zones.
