Proper load calculations prevent short cycling and oversized units that waste energy during long Texas cooling seasons. An accurately sized AC runs longer, more efficient cycles instead of frequent on-off patterns that spike utility costs. At Arktikos AC and Heating, we perform thorough sizing to match your home's actual cooling load.

Frozen coils typically result from restricted airflow due to dirty filters, blocked return vents, or low refrigerant levels. These issues prevent proper heat exchange, causing moisture to freeze on the evaporator coil. Restoring airflow and repairing refrigerant leaks resolves the problem and prevents recurring freezing.

Replacement makes sense when your furnace is over 15 years old, requires frequent repairs, or shows uneven heating and rising energy costs. Aging heat exchangers and outdated efficiency also signal it's time for a new system. Modern furnaces deliver better performance during unpredictable Texas winter cold snaps.

A heat pump provides both heating and cooling by transferring heat, making it energy-efficient for mild Texas winters. A furnace generates heat through combustion or electric resistance, delivering stronger warmth during rare deep freezes. Heat pumps work well in the Houston climate's typically moderate winter temperatures.

Annual maintenance for both heating and cooling systems is recommended, ideally before peak summer heat and winter cold fronts. Seasonal inspections catch worn components early, improve efficiency, and reduce emergency breakdowns. At Arktikos AC and Heating, our maintenance plans include filter checks, cleaning, and performance testing.

Yes, leaking ducts allow conditioned air to escape into attics or crawl spaces, forcing your AC to run longer and work harder. This wastes energy and creates uneven room temperatures throughout your home. Duct sealing and repair restore efficiency and improve comfort in large Texas homes.

Clear the area around your indoor and outdoor units, replace or note your air filter condition, and write down any unusual sounds or performance issues. This helps technicians diagnose problems faster and ensures accurate troubleshooting. Providing system age and past repair history is also helpful.

High Gulf Coast humidity increases the cooling load on your system, requiring it to remove moisture and lower temperature simultaneously. Undersized units, clogged coils, or low refrigerant reduce dehumidification capacity. Systems designed for long cooling seasons and humidity control perform better in this climate.

Upgrades typically include air purification systems, advanced filtration, and duct cleaning to remove dust buildup and airborne contaminants. These solutions address humidity concerns and allergens common in Houston homes. At Arktikos AC and Heating, we also inspect ducts for leaks that affect air quality.

The reversing valve changes refrigerant flow direction, allowing the heat pump to switch between heating and cooling modes. In cooling mode, it moves heat outdoors; in heating mode, it pulls heat from outside air into your home. Reversing valve failures cause the system to get stuck in one mode.

Neglecting filter changes and skipping annual maintenance leads to restricted airflow, frozen coils, and premature system failure. Dirty filters force the AC to work harder, increasing energy bills and repair frequency. Regular filter replacement and seasonal tune-ups extend equipment life significantly.

Yes, after-hours emergency service typically includes an additional fee to cover technician availability outside normal business hours. At Arktikos AC and Heating, our after-hours service fee starts at $150 plus the actual repair cost. We provide clear pricing communication before beginning any work.
