Alpine is a fourth-generation, family-owned business proudly serving Central NJ as the region’s premier air conditioning and heating company for more than five decades. We specialize in HVAC repairs, system replacements, and ongoing maintenance. Custom HVAC Solutions: We design systems specifically for your home’s size and your financial goals, with robust rebates, reduced utility bills and 0% financing available for up to 7 years. Honest, Skilled Technicians: Our licensed, fully trained technicians are focused on fixing the problem, not upselling you on unnecessary equipment or services. Seasonal Tune-Ups & Protection Plans: Keep your system running efficiently with seasonal tune-ups and take advantage of our service contracts for year-round peace of mind. Beyond Heating & Cooling: We also install hot water heaters, indoor air quality solutions like humidifiers and air cleaners, as well as generators and sump pumps to keep your home protected in emergencies.

"I’ve been an Alpine customer since 1975. Alpine is a remarkable example of a small business model (regardless of industry) that other businesses would be smart to emulate. It’s astounding, how they continue to flourish given accelerated market threats, market opportunities and government regulations. They also figured out how to stay more than relevant even with rapidly changing technologies, suppliers and price, along with the active consolidation of small companies by the behemoths (e.g. public utilities, big-box). Their secret sauce is their founding principles of authentic commitment to customer perceived value and continuing to grow/train their exceptional technical service folks. Congratulations on achieving and sustaining your founding vision. Well done! --------------------------My Alpine History------------------------------------------------ I moved to NJ in 1975 and began an immediate search for the best services providers (e.g. MDs, HVACs, Auto Mechanics). I have extremely high standards in terms of quality, price, customer focus and ethics. Furthermore, because of my professional background as a senior consultant for IBM, I am very detailed and fact oriented. All houses in my development had been built 15 years earlier with ducts for forced-air heating only. I brought 3 specialist contractors to evaluate installing AC using the existing ducts. Art Staloff (the owner of Alpine Refrigeration, founded 1972) was the only contractor whose assessment seemed credible and reasonably priced and then proved to be absolutely true. Over a 44 span, I’ve exclusively used Alpine for all my HVAC needs and most recently a whole-house generator. I’ve also taken advantage of their well-priced and high-value pre-season service agreements Paul Raskas East Brunswick, NJ"

Boiler Repair questions, answered by experts

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

Clean regularly, check for leaks, and schedule annual inspections for safety and efficiency.

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

If you have multiple radiators, start by bleeding a first-floor radiator that is farthest from the boiler. Work your way toward the boiler on the first floor before moving to the next floor, where you’ll again start by bleeding the radiator farthest from the boiler. Continue this pattern for radiators on each floor until they’ve all been bled.
