Robert and Josh installed my new Water Commander water powered sump pump back up. They were knowledgeable, professional and everything worked out great. No more worries about power outages and the basement flooding!
Jefferson Plumbing continues to be reliable, trustworthy and quick to turn up! And their team simply great to work with
Great service, as always, prompt, courteous, problems solved, very fair pricing
The technician was excellent patient and very knowledgeable. His manner was open and friendly. He kept me informed as he worked which I greatly appreciated.
Technician worked very efficiently and was very careful and kept work areas clean and tidy. Was very intelligent in solving problems as they were encountered.
We have recently had the pleasure of working with Redding's for a new HVAC installation, new hot water heater, and new sump pump. We had an old system and had a broken wire that disabled our AC on a hot day. We got immediate service and began discussing replacing the old indoor and outdoor equipment. Mike Brooks treated us like we were part of his family in helping us understand the options we should consider and ultimately what to install. That all went well and then they noticed we had a very old hot water heater - with no emergency shut off capabilities. So we replaced that. Then I realized we had an old sump pump with an old battery back-up. They replaced that too. Then we put their sign in our yard to tell the neighbors who to call for their HVAC needs. Super professional! When you see their work, you know you have worked with master craftsmen! 100% recommend to everyone!
HVAC Installation & Service performance guide for Princeton, New Jersey
Climate averages are state-level reference values, not city-specific measurements.
Climate impact in Princeton, New Jersey
Princeton, New Jersey sits in a Mixed-Humid climate zone with average summer highs near 85°F and winter lows near25°F. Those swings load the evaporator coil, blower motor, refrigerant lines, and condensate drain. Keep a clean MERV filter to protect the compressor.
Seasonal swings stress refrigerant lines and condenser capacity. Verify charge and airflow to protect the evaporator coil.
Most common local breakdowns
Evaporator coil icing from low airflow and clogged filters.
Capacitor failures on the condenser during peak cooling loads.
Low airflow from dirty MERV filters or a weak blower motor causes ice. Ask for airflow and refrigerant superheat checks.
Equipment recommendation
Balanced systems with SEER2 15+ and solid filtration protect the blower motor, coils, and compressor year-round. Seal ductwork and schedule coil cleaning to protect the heat exchanger, capacitor, and compressor.
Heat pumps favor variable-speed compressors and tight refrigerant line sets to stabilize humidity control.
Local code and housing notes
Ask contractors about New Jersey energy code compliance and permits. Older homes often benefit from ductless mini-splits to reduce line-set length and improve zone control.
Mechanical permit for system replacement and condenser swaps.
Post-install inspection covering refrigerant line pressure and condensate drain routing.
Load calculation proof to avoid short-cycling compressors.
Airflow verification (blower motor speed + static pressure).
Always confirm a contractor's license and insurance before hiring.
