Apex Heating & Air Conditioning is a licensed HVAC contractor serving Chattanooga's residential market with a focus on proper system sizing through load calculation and structured maintenance agreements. The company handles new installations, repairs, and preventive service contracts for homeowners across the city.
A full-service HVAC shop that operates on the service side of the market rather than new construction. Apex handles existing system diagnostics, component replacement, seasonal maintenance, and occasional new unit installations for homeowners. The company holds the licensing required to work on air conditioning and heating systems in Tennessee, a legal requirement that distinguishes licensed contractors from unlicensed labor.
Apex offers three service tiers: diagnostic calls, repair jobs, and recurring maintenance plans.
A diagnostic visit costs $89 and includes system inspection and a written estimate. This is standard across most Chattanooga HVAC shops; the value lies in whether the estimate itself is thorough. Repair pricing depends on the problem. A compressor replacement on an air conditioning unit typically runs $1,200 to $2,400 including labor; a refrigerant recharge costs $150 to $300. New unit installation begins around $3,500 for a basic 13 SEER (Seasonal Energy Efficiency Ratio) system and rises to $5,500 or more for higher-efficiency units. SEER ratings matter here: a 16 SEER unit uses roughly 20 percent less energy than a 13 SEER equivalent, which translates to lower utility bills over the system's life but higher upfront cost.
Maintenance plans are where Apex's business model clarifies. A seasonal tune-up plan (spring and fall visits) costs $199 per year. Each visit includes filter replacement, refrigerant level check, electrical connection inspection, and thermostat calibration. The maintenance contract also provides 10 percent off repair labor if a breakdown occurs. For homeowners, this plan makes sense if the system is older than seven years or if repairs in the past two years have exceeded $500; younger systems may not justify the annual fee.
Verify current pricing by calling directly, as service rates shift annually.
Chattanooga's HVAC market includes several licensed competitors. Comfort Systems USA operates multiple locations across the city with higher volume and faster appointment availability; their diagnostic fee runs $99 and they typically handle jobs within 24 to 48 hours. In exchange, their pricing skews toward the higher end, and less time is spent on load calculations for new installs. All Air Systems is a smaller single-location shop with lower overhead, often undercutting Apex on diagnostic fees by $10 to $15, but their maintenance plans are less structured and turnaround time is unpredictable.
Choose Apex if your home is on an older or non-standard electrical panel, if you prefer a single point of contact for multi-year service relationships, or if you value detailed system documentation. Choose Comfort Systems if you need emergency same-day service or are installing a high-end unit with manufacturer support. Choose All Air Systems only if budget is the sole factor and you do not require a formal maintenance agreement.
Apex's model fits established homeowners in Chattanooga who plan to stay in their house for five or more years and want to extend their current system's lifespan through preventive maintenance. Single-family home owners with systems built before 2010 benefit most from their diagnostic rigor. Renters and short-term residents should skip the maintenance plan and use Apex only for emergency repairs.
Apex does not offer emergency after-hours service, a weakness if your system fails at 2 a.m. in July. If 24/7 availability is essential, Comfort Systems or a larger regional player is necessary.
Call during business hours (Monday to Friday, 8 a.m. to 5 p.m.; Saturday 9 a.m. to 2 p.m.) to schedule a diagnostic. A technician arrives within three to five business days, walks through your system, and delivers a written estimate on-site. If you decide to proceed with repairs or maintenance, payment is due before work begins. Apex accepts major credit cards and offers financing through a third-party lender for installs over $2,500.
Apex operates from a service facility in East Brainerd with street parking and a small lot. Technicians are dispatched from this location and arrive in marked vans. There is no customer waiting area; appointments are conducted at your home. The business is open Monday to Friday 8 a.m. to 5 p.m. and Saturday 9 a.m. to 2 p.m., closed Sundays and major holidays.
Apex earns inclusion in this guide because it combines proper system sizing methodology with transparent pricing, a combination uncommon enough in Chattanooga's HVAC market to matter to homeowners comparing options.
