Hillsborough Cooling System Services

Complete AC Solutions for Your Home
Our AC repair services cover everything from simple fixes to complex system overhauls. We handle refrigerant leaks, compressor issues, electrical problems, and airflow restrictions that keep your system from cooling effectively. For Hillsborough homes, we’re particularly experienced with the ductless mini-split systems that work well in our climate. These systems offer efficient zone control and are perfect for homes that want to avoid extensive ductwork modifications. We also provide preventative maintenance that catches small problems before they become expensive repairs. Regular tune-ups keep your system running efficiently and help you avoid the inconvenience of unexpected breakdowns during warm weather.

How do I know if my AC needs repair or replacement?

If your repair costs are approaching half the price of a new system, replacement usually makes more sense financially. Age is another factor—systems over 10-15 years old often benefit from replacement, especially if they’re requiring frequent repairs. Other signs pointing toward replacement include consistently high energy bills, uneven cooling throughout your home, and systems that struggle to maintain comfortable temperatures. However, many issues that seem major actually have straightforward repair solutions. The best approach is to have a qualified technician assess your specific situation. We’ll give you honest recommendations based on your system’s condition, your home’s needs, and what makes the most financial sense for your situation.
Dirty air filters are the most common culprit. When filters get clogged, your system has to work harder to push air through, reducing efficiency and potentially causing the evaporator coil to freeze up. Refrigerant leaks also gradually reduce cooling capacity. Low refrigerant levels mean your system can’t absorb and release heat effectively, leaving you with warm air coming from your vents. Electrical issues, worn-out capacitors, and dirty coils all contribute to declining performance. Regular maintenance catches these problems early, but once they develop, professional repair is usually necessary to restore proper cooling efficiency.
We offer 24/7 emergency repair services because we understand that AC problems don’t wait for convenient times. During business hours, we typically respond within a few hours of your call. For after-hours emergencies, we aim to have a technician at your location as quickly as possible, usually within the same evening or early the next morning. Our service trucks are fully stocked with common parts, so many emergency repairs can be completed during the initial visit. We prioritize emergency calls from elderly residents, families with young children, and anyone with medical conditions that make temperature control critical for their health and safety.
Yes, we service all major AC system types including central air conditioning, ductless mini-splits, heat pumps, and window units. Our technicians are trained on systems from all major manufacturers including Carrier, Trane, Lennox, Goodman, and others. We’re particularly experienced with the ductless mini-split systems that are popular in Hillsborough homes. These systems offer excellent efficiency and zone control, but they require specialized knowledge for proper diagnosis and repair. Whether your system is a basic single-stage unit or a high-efficiency variable-speed system, we have the expertise and tools to diagnose problems accurately and complete repairs properly.
Our maintenance service includes a comprehensive inspection of all system components, cleaning of the evaporator and condenser coils, checking refrigerant levels, testing electrical connections, and replacing air filters. We also calibrate your thermostat, check ductwork for leaks, inspect the condensate drain, and test safety controls. This preventative approach catches small issues before they become expensive repairs. Regular maintenance typically prevents about 70% of AC breakdowns and helps your system run more efficiently, which can reduce your energy bills. We’ll also give you a written report of our findings and recommendations for any issues that need attention.
Start with regular filter changes—dirty filters make your system work harder and use more energy. Programmable thermostats can also reduce energy consumption by automatically adjusting temperatures when you’re away from home. Sealing ductwork leaks prevents cooled air from escaping into unconditioned spaces like attics or crawl spaces. Even small leaks can waste significant energy over time. For older systems, upgrading to a high-efficiency unit can dramatically reduce energy costs. Modern AC units with high SEER ratings use substantially less electricity than older models, often paying for themselves through energy savings over time.
