- PVPastor Cessy VizMar 9, 20265.0I had an excellent experience with Active Air LLC. From the first call to the completion of the job, their team was professional, responsive, and extremely knowledgeable. They took the time to explain the issue clearly, offered honest recommendations, and made sure everything was running perfectly before leaving. What really stood out was their attention to detail and commitment to customer service. The technicians were punctual, respectful of our church, and worked efficiently without cutting corners. It’s clear they take pride in their work and genuinely care about their customers. They were also incredibly generous and gracious in donating items to support our church, which truly meant a lot to our community. Their willingness to give back speaks volumes about their character as a company. If you’re looking for a reliable, trustworthy HVAC company that delivers high-quality service and genuinely cares about the community, I highly recommend Active Air LLC. I will definitely be using them again for any future heating or cooling needs!
- MMMichael McCarthyFeb 27, 20265.0I can’t recommend Angel and Active Air enough. We had a complicated 'no-heat' situation during a sub-zero freezing stretch in Trumbull where my downstairs furnace was throwing a 'Code 68' communication error. While other companies just wanted to swap the whole unit immediately, Angel took the time to do a real diagnostic. He verified the low-voltage signals to the motor and board to pinpoint the exact failure. He was honest about parts being obsolete for my 12-year-old Rheem and helped me navigate the decision to repair vs. replace without any pressure, even rescheduling his calendar and availability to restore heat to my home asap. If you want a contractor who actually understands the engineering of your HVAC system and won't just sell you a 'quick fix,' call Angel.

- AAAdelinaJan 12, 20265.0Hello everyone! Not to go into too much detail, but my mom’s furnace decided to take an extended vacation in below 30 degree weather. Bon voyage furnace! I called around until I found Active Air. Andrew and staff are a Godsend! Not only did they diagnose the issue, but they worked with professionalism, integrity, and fair pricing. Give them a try, you will not be disappointed!
Frequently Asked Questions About Active Air LLC

Active Air LLC operates as a fully licensed and insured HVAC contractor. Our status as a BBB Accredited Business underscores our commitment to maintaining the highest industry standards. Our team of technicians is not only highly qualified and licensed but also brings over three decades of combined professional experience to every job.
What services do you provide?
As a comprehensive HVAC company, we specialize in both heating and air conditioning services. Our offerings include new system installations, replacements, emergency repairs, and regular maintenance. We also provide indoor air quality solutions, such as air purification and humidity control. Our expertise covers a wide range of systems, including furnaces, boilers, heat pumps, and air conditioners.
What areas do you serve in Connecticut?
We proudly extend our services to both residential and commercial clients in Trumbull and its neighboring areas. Our service area encompasses Bridgeport, Fairfield, Monroe, Milford, Shelton, Stratford, and Westport, ensuring comprehensive coverage for our customers throughout the region.
How long does a typical HVAC system last?
With professional maintenance, most residential and commercial HVAC systems have a lifespan of 15 to 20 years. Regular tune-ups from a certified contractor are the single most important factor in reaching this 20-year milestone and avoiding premature replacement.
Is professional HVAC maintenance really necessary every year?
Yes. Professional service is often required to keep your manufacturer’s warranty valid. Beyond the warranty, an expert inspection identifies hidden safety risks like carbon monoxide leaks or faulty wiring that standard DIY checks cannot detect.
How can a professional contractor lower my monthly energy bills?
A licensed technician optimizes your system’s efficiency by cleaning coils, calibrating thermostats, and ensuring proper refrigerant levels. This prevents the unit from "overworking," which can reduce your monthly utility costs by 10% to 20%.
What are the safety risks of DIY HVAC repair?
HVAC systems involve three major hazards: high-voltage electricity, pressurized refrigerants, and combustible gas lines. Attempting repairs without specialized training can lead to electrical fires, toxic exposure, or dangerous gas leaks. Professional contractors follow strict safety protocols to keep your home and family secure.
How do I know if I should repair or replace my HVAC unit?
If your system is over 15 years old, requires frequent repairs, or has caused a sudden spike in energy bills, a replacement is likely the most cost-effective long-term move. A professional load calculation from Active Air LLC can determine if a new, high-efficiency system will pay for itself through energy savings.
Why does my HVAC manufacturer require a licensed contractor for service?
Most major brands (like Carrier, Trane, or Rheem) specify that their warranties only remain valid if the system is installed and maintained by a licensed professional. DIY work or "handyman" repairs can void your coverage, leaving you responsible for the full cost of major parts.
What is a ductless mini-split system and how does it work?
ductless mini-split is a highly efficient heating and cooling system that doesn't require bulky ductwork. It consists of an outdoor compressor and one or more indoor air-handling units. Unlike traditional systems, it uses a small conduit to transfer heat directly between the units. In the summer, it pumps heat out of your home; in the winter, it reverses the process to pull heat from the outside air and bring it indoors.
Can a mini-split really heat my home during a cold Connecticut winter?
Yes! Modern "cold-climate" heat pumps are designed to operate efficiently even when temperatures drop well below freezing. Many units can provide effective heating down to -13°F or lower. They are an excellent, cost-effective alternative to baseboard electric heat or oil furnaces, often providing 2 to 4 times the efficiency of traditional heating methods.
How much can I save on my energy bills by switching to a heat pump?
Homeowners often see significant savings—sometimes up to 30–50% on their heating and cooling costs. Because mini-splits avoid the energy loss associated with ductwork (which can account for over 30% of a home's energy consumption) and utilize "inverter technology" to adjust speeds precisely, they use far less electricity than standard central air or electric heaters.
How long does the installation process take?
One of the biggest advantages of a mini-split is the non-invasive installation. Since no ductwork is required, our team can often complete a single-zone installation in just one day. We only need to drill a small three-inch hole in an exterior wall to connect the indoor and outdoor units, minimizing the disruption to your home.
Can I control the temperature in different rooms separately?
Absolutely. This is known as "zoning." With a multi-zone mini-split system, you can have individual indoor units in different rooms (like bedrooms, a basement, or a home office), each with its own thermostat or remote. This allows you to heat or cool only the rooms you are using, further increasing your comfort and energy savings.
Reasons to Hire an HVAC Contractor?
Professional HVAC services ensure your system operates at peak efficiency and safety. Here is why expert handling is essential:
Optimal Performance: Proper installation and maintenance guarantee indoor comfort and high air quality.
Cost Savings: Professionals improve energy efficiency and prevent expensive breakdowns, extending your system’s lifespan.
Safety & Reliability: Experts follow strict protocols to handle complex electrical and gas components safely.
Expert Repairs: From routine check-ups to emergency fixes, qualified technicians provide peace of mind and reliable results.
When should I replace my water heater?
Most traditional units last 8 to 12 years. If your unit is over 10 years old, shows signs of rust at the base, or makes "popping" sounds (indicating sediment buildup), it’s time to shop for a replacement before it leaks.
What is a Heat Pump (Hybrid) Water Heater?
These units pull heat from the surrounding air to warm your water rather than generating heat directly. They are the most energy-efficient option on the market and can save a typical CT family up to $500 per year on electric bills.
