We Actually Know New Canaan Homes

Temp Assure Heating Air Conditioning & Refrigeration serves New Canaan homeowners who need HVAC solutions that work with their specific homes and climate challenges. We’re not the cheapest option in town—and that’s exactly why you should call us. New Canaan’s housing tells a story. Those beautiful colonials and historic homes built in the 1940s through 1960s? They need HVAC approaches that work with older construction, existing ductwork, and spaces that weren’t designed for modern efficiency standards. The newer luxury builds in areas like Ponus Ridge? They benefit from smart technology integration, zoned systems, and advanced air quality solutions. We understand these differences because we work in these homes every day. We know that a system sized for a ranch in Texas won’t work in a New England colonial. We know that New Canaan’s temperature swings from below freezing to over 90 degrees demand equipment that can handle extremes without breaking down. And we know that when your system fails during a Connecticut winter, it’s not just uncomfortable—it’s potentially dangerous.

HVAC Installation Process New Canaan

No Surprises, No Runaround, Just Results

First, we evaluate your home’s actual needs—not what some generic sizing chart says you should have. We measure spaces, check insulation, evaluate existing ductwork, and assess your electrical capacity. Your home’s age, layout, and construction style all affect what equipment will work best and most efficiently. Then we give you a detailed estimate that explains exactly what you’re getting and why. No vague line items or surprise charges later. We break down equipment costs, labor, permits, and any additional work needed. You’ll understand every aspect of the investment before we start. Installation happens with minimal disruption to your routine. We protect your floors and furniture, work efficiently, and clean up thoroughly. More importantly, we test everything extensively before we leave. You get a complete walkthrough of your new system, clear operating instructions, and our direct contact information for any questions. The goal isn’t just to install equipment—it’s to give you an HVAC system that handles New Canaan’s climate challenges reliably for years to come.

Everything Your System Needs to Survive Here

New Canaan’s climate is particularly hard on HVAC equipment. Summer humidity levels stress air conditioning systems. Winter temperatures that drop well below freezing put heating systems through extreme cycles. And the constant temperature swings throughout the year create expansion and contraction that lead to component failures. Our services address these specific challenges. Emergency repairs when systems fail during extreme weather. Preventive maintenance that catches problems before they leave you without heat or cooling. Complete system replacements when equipment reaches the end of its useful life in Connecticut’s demanding climate. We also handle the indoor air quality issues common in New Canaan homes. Older properties often struggle with dust, allergens, and humidity control. Newer construction sometimes lacks adequate ventilation. Our solutions include advanced filtration systems, humidity control, and ventilation improvements that create healthier indoor environments. The reality is that HVAC systems work harder in New Canaan than they do in milder climates. Equipment that might last 20 years elsewhere often needs replacement after 12-15 years here. Regular professional maintenance extends system life and prevents the emergency breakdowns that always seem to happen during the worst weather. We help you get the most from your investment while avoiding the stress and expense of unexpected failures.

How often should I schedule HVAC maintenance in New Canaan?

Twice a year, minimum. New Canaan’s extreme seasonal changes put extra stress on HVAC equipment, making regular maintenance more critical than in milder climates. Spring service prepares your air conditioning for summer heat and humidity. Fall service ensures your heating system is ready for Connecticut winters. During spring maintenance, we clean air conditioning coils, check refrigerant levels, test electrical connections, and verify that all cooling components work properly. This prevents mid-summer breakdowns when you need AC most and every contractor is swamped with emergency calls. Fall maintenance focuses on heating systems—cleaning burners, inspecting heat exchangers, testing safety controls, and checking gas connections. We also examine ductwork for leaks that waste energy and reduce comfort. Regular maintenance catches small problems before they become expensive repairs and keeps your equipment running efficiently, which reduces energy costs and extends system life.

What size HVAC system do I need for my New Canaan home?

System sizing requires detailed calculations specific to your home—square footage alone isn’t enough. New Canaan’s mix of historic and modern construction means homes with identical square footage can have dramatically different heating and cooling needs. Older homes often need larger systems due to less efficient insulation, single-pane windows, and air leakage. But installing an oversized system creates problems: short cycling, poor humidity control, and higher energy costs. An undersized system runs constantly during extreme weather and can’t maintain comfortable temperatures. We perform Manual J load calculations that account for your home’s insulation, window placement, ceiling height, ductwork condition, and orientation to the sun. We also consider New Canaan’s specific climate data—not generic regional averages. This ensures properly sized equipment that maintains consistent comfort efficiently, regardless of whether you live in a 1950s colonial or a modern custom build.

Should I repair or replace my aging HVAC system?

If your system is over 12-15 years old and needs frequent repairs, replacement usually makes more financial sense. New Canaan’s climate is particularly hard on HVAC equipment—systems that might last 20 years in milder areas often fail sooner here due to extreme temperature cycles. Consider total ownership costs, not just the immediate repair bill. Older systems use significantly more energy, break down more frequently, and replacement parts become expensive and hard to find. A new high-efficiency system typically pays for itself through lower energy bills and fewer service calls. Key replacement indicators include: rising energy bills despite similar usage, frequent repair calls, uneven temperatures throughout your home, or inability to maintain comfort during extreme weather. If your system struggles during New Canaan’s hottest summer days or coldest winter nights, it’s time to upgrade. Modern equipment handles Connecticut’s climate challenges much better than systems designed 15+ years ago.

Do you provide emergency HVAC service in New Canaan?

Yes, we provide 24/7 emergency service because HVAC failures don’t wait for business hours—they typically happen during the worst weather when you need your system most. In New Canaan, a heating failure during a winter storm or AC breakdown during a heat wave can quickly become dangerous. We prioritize emergency calls based on safety and urgency. Heating failures in winter, cooling failures during heat advisories, gas leaks, and electrical problems get immediate response. We carry common repair parts and diagnostic equipment to fix many problems on the first visit. Our emergency service includes temporary repairs to restore basic function when immediate permanent solutions aren’t possible. If we can’t fix your system immediately, we’ll discuss options to keep your home habitable until we can complete proper repairs. Emergency service costs more than scheduled maintenance, but when your family’s comfort and safety are at risk, having reliable help available 24/7 is invaluable.

What HVAC brands do you install and service in New Canaan?

We install and service all major HVAC brands including Carrier, Trane, Lennox, Rheem, Goodman, York, and others. Our technicians receive ongoing manufacturer training to stay current with new technology and warranty requirements across different equipment lines. Brand selection depends on your specific needs, budget, and home characteristics. Some manufacturers excel in energy efficiency, others focus on durability in harsh climates, and some offer superior smart home integration. We help you evaluate options based on what matters most for your situation and New Canaan’s demanding climate. We maintain relationships with multiple suppliers to ensure competitive pricing and reliable parts availability. This means we can service any major brand equipment, regardless of what you currently have installed. Whether you need routine maintenance on a 10-year-old system, emergency repairs on equipment we didn’t install, or complete system replacement, we have the expertise and parts access to handle any major brand properly.

How can I reduce my energy bills with HVAC upgrades?

Energy efficiency improvements can reduce your heating and cooling costs by 20-50%, which is significant given that HVAC accounts for over half of most New Canaan homes’ energy usage. The biggest impact comes from upgrading to properly sized, high-efficiency equipment with professional installation. Smart thermostats provide precise temperature control and scheduling, reducing waste when you’re away. Programmable settings can save 10-15% on energy costs by automatically adjusting temperatures based on your schedule. Zoned systems allow heating and cooling only the areas you’re using. Ductwork improvements often provide dramatic savings. Leaky ducts waste 20-30% of conditioned air in many homes. Proper sealing and insulation keep heated and cooled air where it belongs—in your living spaces, not your attic or basement. Combined with high-efficiency equipment, these improvements often pay for themselves within 3-5 years through lower utility bills.
