Frequently Asked Questions

A typical central air conditioning installation takes 4 to 8 hours for a standard replacement when existing ductwork is in good condition. For Houston homes, VeriChill's comprehensive process (including performance verification, airflow balancing, and humidity testing) may extend slightly longer to ensure your system operates at peak efficiency from day one. New installations requiring ductwork modifications or electrical upgrades can take 1 to 2 days. We provide clear timeline expectations during your consultation so you can plan accordingly.

The right AC size depends on much more than square footage. VeriChill performs a thorough on-site assessment for every project — evaluating your home's insulation, window types and orientation, ceiling heights, ductwork condition, airflow, and Houston's extreme humidity. Oversized units cool quickly but short-cycle, leaving your home cool but clammy. Undersized units run constantly without ever reaching comfortable temperatures. Our hands-on assessment process ensures you get a properly sized system, not a rule-of-thumb guess based solely on square footage.

Consider replacing your AC if it is 10-15 years old and requires frequent repairs, especially if repair costs exceed 50% of a new system's price. Other warning signs include rising energy bills without increased usage, uneven cooling or humidity problems, unusual noises, and systems still using R-22 refrigerant (phased out and increasingly expensive). In Houston, where AC systems work harder than in most of the country, we often see systems reach the end of life sooner than the national average.

VeriChill's installation process begins with site preparation and protection of your home's flooring and furnishings. Our technicians carefully remove and dispose of your old equipment, then install and connect your new system to the existing ductwork and electrical system. We run complete system tests, measure airflow, verify temperature differentials, and program your thermostat. Before we leave, we conduct a homeowner orientation to explain how your new system operates and the maintenance requirements.

SEER2 ratings replaced older SEER ratings in 2023, using more realistic testing conditions that better reflect real-world performance. In Texas and the Southeast region, new AC systems must meet a minimum SEER2 of 14.3 for units under 45,000 BTU/h. Higher SEER2 ratings mean lower operating costs, which is especially important given Houston's 8-9 month cooling season. VeriChill helps you balance upfront cost with long-term energy savings, and can walk you through flexible financing options to make a higher-efficiency system work within your budget.

For Houston's mild winters, heat pumps offer excellent efficiency since they provide both heating and cooling from a single system. They operate efficiently down to about 35-40°F, covering most days of the Houston winter. Gas furnaces heat faster during cold snaps and work well when natural gas is already installed. Dual-fuel systems combine both, using the heat pump for mild days and switching to gas backup during extreme cold. VeriChill evaluates your home's existing infrastructure and comfort preferences to recommend the best option.

Houston's average humidity exceeds 75%, creating unique comfort challenges that standard AC sizing doesn't address. A properly designed system removes moisture while cooling, but oversized units cool air too quickly and shut off before adequately dehumidifying, leaving homes cool but uncomfortably clammy. VeriChill designs every installation with humidity control as a primary consideration, recommending variable-speed equipment and proper sizing that runs longer cycles for better moisture removal.

A few simple steps help ensure a smooth installation. Clear the area around your indoor unit (usually in a closet, garage, or attic) and outdoor condenser location so technicians have easy access. Move vehicles from the driveway if the crew needs space for equipment. Secure pets in a separate room away from the work areas. VeriChill crews protect your flooring and furnishings throughout the project, but moving fragile items near the work zone is always a good idea. Plan to be home during installation so we can walk you through your new system's operation and answer questions before we leave.

Spring (March-April) and fall (September-October) offer the best conditions for HVAC installation. Moderate temperatures mean you won't be without climate control during extreme weather, and contractors typically have more scheduling flexibility. However, don't wait if your current system is struggling. Emergency summer replacements often mean higher labor costs and rushed decisions. If your system is aging, schedule a consultation during the off-season to plan your replacement before you're in crisis mode.

While national averages suggest 15-17 years for central AC systems, Houston's extreme conditions (an 8-9-month cooling season, high humidity, and systems that work harder than almost anywhere else) often result in shorter lifespans of 10-15 years. Proper sizing, quality installation, and regular maintenance extend system life. VeriChill selects equipment rated for high-demand, extended-operation environments and uses corrosion-resistant components suited for Gulf Coast conditions to maximize your system's longevity.
