How do I know what size AC system I need for my San Mateo home?

Proper AC sizing depends on much more than just your home’s square footage. We perform a detailed cooling load calculation that considers your home’s insulation, window placement, ceiling height, and local climate conditions.In San Mateo’s Mediterranean climate, many homes need different sizing considerations than inland areas. We factor in your home’s orientation, shading, and the number of occupants to determine the right capacity.An oversized system will cycle on and off frequently, wasting energy and failing to properly dehumidify your home. An undersized system will run constantly and struggle to maintain comfortable temperatures. Our load calculation ensures you get exactly the right capacity for efficient, comfortable cooling.
Central air conditioning uses your home’s existing ductwork to distribute cool air throughout the house from a single outdoor unit. This works well for homes with good existing ductwork and provides consistent whole-home cooling.Ductless mini-split systems use individual indoor units in each room or zone, connected to an outdoor unit by refrigerant lines. These are ideal for homes without existing ductwork, room additions, or when you want independent temperature control in different areas.In San Mateo County, many older homes lack adequate ductwork, making ductless systems an excellent option. Mini-splits also offer superior energy efficiency because you’re not losing conditioned air through leaky ducts, and you can cool only the rooms you’re using.
Most residential AC installations take one to two days, depending on the system type and complexity of your home’s setup. A straightforward central air replacement might be completed in one day, while a new installation requiring electrical work or ductwork modifications could take longer.Ductless mini-split installations are often faster because they don’t require extensive ductwork. However, we never rush the process—proper installation is critical for system performance and longevity.We coordinate with you to schedule installation at your convenience and provide accurate time estimates upfront. Our team arrives prepared with all necessary materials and equipment to complete the job efficiently without compromising quality.
Yes, most AC installations in San Mateo require permits, especially for new installations or major replacements involving electrical work. The city requires permits to ensure installations meet safety codes and energy efficiency standards.We handle all permit applications and scheduling of required inspections as part of our installation service. This ensures your installation is compliant with local building codes and won’t cause issues if you sell your home later.Attempting to skip permits might save money initially, but it can create serious problems during home sales or insurance claims. Our permit handling gives you peace of mind that everything is done properly and legally.
Your new AC system needs regular filter changes—typically every 1-3 months depending on usage and filter type. This is the most important maintenance task you can do yourself to keep your system running efficiently.Professional maintenance should be performed annually, ideally before the cooling season begins. This includes cleaning coils, checking refrigerant levels, inspecting electrical connections, and verifying proper operation of all components.In San Mateo’s relatively mild climate, systems don’t work as hard as in hotter regions, but regular maintenance still extends equipment life and maintains efficiency. We provide detailed maintenance schedules and can set up annual service appointments to keep your system in peak condition.
AC installation costs vary significantly based on system type, size, and installation complexity. Basic central air systems typically start around $3,000-5,000, while high-efficiency systems or complex installations can cost $8,000-15,000 or more.Ductless mini-split systems often cost less for single-zone installations but can add up for whole-home coverage. The key is getting the right system for your specific needs rather than just the cheapest option.We provide detailed, transparent estimates that break down equipment and labor costs. Our pricing includes all necessary permits, inspections, and testing—no surprise charges. We also offer financing options to help make quality installation affordable for your budget.
