Questions and Answers

My air conditioning just quit on a hot day in Downtown New London. How fast can a technician get here?

Our dispatch routes from Hatton Park use US Highway 45 for direct access to the downtown area, ensuring a typical 5-10 minute response for urgent no-cool calls. We prioritize these emergencies, especially during peak heat hours, to prevent further stress on the system and restore comfort quickly. A same-day diagnosis is standard to address the issue before it escalates.

My furnace is original to my 1975 New London home. Is that too old?

A system from 1975 is 51 years old, which is well beyond its expected lifespan of 15-20 years. In humid continental climates like ours, the constant strain of seasonal temperature swings accelerates wear. This advanced age is the primary reason for common failures like frozen evaporator coils, where accumulated grime on the coil and reduced refrigerant charge from micro-leaks cause a system-wide efficiency collapse.

Can my older galvanized steel ducts handle a high-grade air filter for pollen and PM2.5?

Galvanized steel ductwork is generally robust, but adding a high-MERV filter like a MERV-13 for pollen and fine particulate matter requires a static pressure check. Older systems were not designed for the airflow restriction these filters create. We measure the static pressure to ensure your blower motor can handle it; if not, we recommend a media cabinet or a standalone air purifier to achieve the desired indoor air quality without straining the HVAC system.

What does the new 13.4 SEER2 minimum efficiency standard mean for my replacement?

The 2026 SEER2 mandate ensures all new central air conditioners meet a higher baseline of efficiency, which directly lowers electrical consumption. With New London utility rates at 0.14/kWh, upgrading to a 16+ SEER2 unit can significantly reduce summer bills. The active Inflation Reduction Act rebates, with caps up to $8,000, can offset much of the upfront cost for qualifying high-efficiency systems, making the long-term savings even more compelling.

What are the permit and safety rules for installing a new system with the latest refrigerant?

All HVAC replacements in New London require a permit from the City of New London Building Inspection Department. Since 2025, systems using mildly flammable A2L refrigerants like R-454B must comply with updated safety standards (UL 60335-2-40). This mandates specific leak detection sensors, updated electrical classifications, and special technician certification. We handle the permit process and ensure the installation meets all 2026 codes for safety and performance.

My old AC struggles when it hits the 90s. Wasn't it designed for our weather?

Older systems were typically sized for an 87°F design temperature, a historical average. New London now regularly experiences summer highs in the mid-90s, exceeding that design limit and causing extended run times that overwhelm the unit. Modern systems using R-454B refrigerant are engineered for these higher ambient temperatures, maintaining stable pressure and efficient cooling capacity during the peak heat that challenges older equipment.

My Ecobee thermostat is showing an E4 alert. What does that mean for my system?

An Ecobee E4 alert specifically indicates a loss of communication with your outdoor AC or heat pump unit. In New London, this often points to a tripped high-pressure switch, a blown low-voltage fuse, or a damaged control wire, frequently triggered during our high-humidity cooling season. This signal allows for proactive diagnosis before a complete system failure, preventing a frozen coil or compressor overload on the next hot day.

I use natural gas heat. Does a heat pump make sense with our cold winters?

Modern cold-climate heat pumps are effective in New London's winters, operating efficiently at temperatures well below freezing. The economic case involves comparing your natural gas rate to the 0.14/kWh electricity rate, especially during the utility peak hours of 1-7 PM. With the substantial federal rebates available, a dual-fuel system that uses a heat pump as the primary source and gas as backup during extreme cold can maximize year-round savings and comfort.
