Year-round comfort in a Ridgewood home or business depends on equipment that runs reliably in January cold and July humidity alike. When either side of that equation slips, you notice fast. That is where a dependable heating and air conditioning partner earns its keep, and it is the work that Katham Heating and Air Conditioning LLC has focused on since we opened our doors in 1985.
What Full-Service HVAC Means in Ridgewood, NJ
Serving Ridgewood means covering the whole span of climate control equipment, not just one piece of it. A furnace that short-cycles in winter and a condenser that freezes over in summer are two very different problems, but both keep a household or a workplace uncomfortable. Our approach treats heating and cooling as a connected system, because in most properties they share ductwork, thermostats, and electrical circuits.
Over nearly four decades, we have grown into one of the area’s leading residential and commercial heating and air conditioning companies. That reputation was built on straightforward habits: an accessible, hands-on head of the company, a knowledgeable staff, courteous service, and fair pricing. We also provide around-the-clock assistance, because a heat outage during a cold snap or an air conditioning failure in a heat wave will not wait for regular business hours.
Heating Repair and Installation
Heating failures tend to announce themselves in stages. A furnace may rumble on startup, produce uneven heat between rooms, or trip its high-limit switch before it stops working entirely. We diagnose these symptoms by working backward from the complaint. That process includes checking the thermostat signal, verifying gas pressure and burner ignition, inspecting the heat exchanger for cracks, and measuring temperature rise across the unit to confirm it matches the manufacturer’s specification.
When repair is not the practical choice, replacement gives you a cleaner path forward. Sizing matters more than most people expect. An oversized furnace heats a space quickly and then shuts off, cycling on and off in a way that wastes fuel and wears out components. We calculate heating load based on square footage, insulation, window area, and ceiling height, then match that figure to a unit rated in BTUs and an AFUE efficiency percentage that fits your goals. High-efficiency condensing furnaces can reach AFUE ratings in the mid-to-high 90s, converting nearly all of their fuel into usable heat.
Air Conditioning Service and System Installation
Cooling equipment lives a hard life in the humid Northeast summer. Refrigerant charge, coil cleanliness, and airflow all affect how well a system pulls heat and moisture out of your indoor air. When an air conditioner underperforms, we test static pressure across the ducts, inspect the evaporator and condenser coils, check refrigerant levels against the nameplate charge, and confirm the compressor draws the correct amperage under load.
For new installations, the same load-calculation discipline applies. A properly sized air conditioner, rated by tonnage and SEER2 efficiency, will run longer, quieter cycles that hold both temperature and humidity steady. That steady operation is what makes a room feel genuinely comfortable rather than merely cold. We handle the full scope of the job, from setting the condenser pad and running line sets to charging the system and verifying the thermostat controls both stages of a variable-speed unit correctly.

How We Approach a Service Call
Every visit starts with listening. The symptoms you describe often point us toward the fault faster than any single test, so we ask questions before we open any panel. From there we move through a repeatable sequence: confirm the complaint, isolate the failing component, verify our finding with a measurement rather than a guess, and explain what we found in plain terms before any work begins.
This methodology matters because HVAC systems fail in ways that mimic one another. A weak airflow complaint might trace back to a clogged filter, a failing blower motor, a collapsed duct, or a frozen coil. Jumping to a conclusion wastes your money and our time. By measuring temperature splits, static pressure, and electrical draw, we separate the actual cause from the symptoms it produces. That habit is a large part of why customers keep calling Katham Heating and Air Conditioning LLC across changing seasons and changing equipment.
Practical Situations We Handle Regularly
Different buildings present different challenges. An older Ridgewood home with radiator heat and a later-added central air system needs careful coordination so the two do not fight each other. A newer construction with tight envelope sealing may hold heat well but struggle with fresh-air ventilation and humidity control. A commercial space might need staged cooling to handle occupancy swings between a busy afternoon and an empty evening.
We adapt to each of these. For the retrofit home, that might mean adding a properly sized air handler and routing duct without disturbing existing framing more than necessary. For the sealed new build, it might mean recommending balanced ventilation to keep indoor air fresh. For the commercial client, it means specifying equipment that stages its output to match real demand rather than blasting a fixed amount of cooling regardless of the room.
Whatever your equipment and whatever the season, our goal stays the same. Your satisfaction is what matters to us most, and we strive for excellence in every service call. Call us today, and see us today, for heating and air conditioning service in Ridgewood, NJ that treats your comfort as the priority it should be.
