Getting Your Mini Split Ready Before the First Central Texas Heat Wave
Updated September 2026
Central Texas summers do not ease in gently. Early heat waves regularly push temperatures past 100 degrees, putting immediate stress on home cooling systems. Preparing your ductless heat pump before the first severe stretch ensures your living space stays comfortable when the grid and local HVAC schedules get overwhelmed.
Whether you need to inspect an existing system or install a brand-new unit to cover a hot room, planning ahead saves money and stress. Old West Minisplits provides flat-price new mini split installations from Waco down to San Antonio, eliminating sales visits and hidden fees before the summer rush begins.
Essential Pre-Summer Maintenance for Existing Units
Before high temperatures arrive, clean the washable air filters located inside the indoor wall unit. Clogged filters restrict airflow, forcing the compressor to work harder and reducing cooling efficiency. Outside, clear away weeds, leaves, and debris around the outdoor unit to maintain proper airflow across the coils. If a system is not cooling properly, try turning off the power breaker for ten minutes to reset the control board.
When Pre-Summer Repairs Are No Longer Worth the Cost
If an old window unit, portable air conditioner, or aging system is already struggling, spending money on service calls during peak summer can get expensive quickly. Window units and portable ACs are cheap upfront, but they cool one room loudly, block windows, drip condensate, and are far less efficient. Most local HVAC contractors are quote-based, require an in-home sales visit, and charge $3,000-$6,000 per zone for a custom ductless quote. If your current setup cannot handle the incoming heat, switching to a flat-price replacement is often smarter than chasing repairs on an old unit.
