Personalized AC Installation for Long-Term Comfort

Upgrading or installing a cooling system can feel like a big decision. That's why our process begins with a thorough assessment of your home's layout, square footage, insulation, and current equipment. Our certified technicians then recommend efficient systems that align with your cooling needs, energy goals, and budget.

Routine Service That Extends System Life

The best way to protect your AC system from wear and tear is with consistent, professional maintenance. Our preventive service plans are designed to help your system run at peak efficiency and avoid surprise breakdowns. This is especially important during the summer months when AC units are under the most stress.

During a maintenance visit, our technicians clean and inspect key components, check refrigerant levels, tighten electrical connections, and replace filters as needed. These steps help your system perform better, use less energy, and last longer. If you're looking to protect your investment, our air conditioning services in New Brunswick offer the routine care your system needs year-round.

Fast Repairs When You Need Relief

Nothing disrupts a summer day faster than a broken air conditioner. If your unit stops working, runs unevenly, or makes unusual noises, Guaranteed Service will be there with prompt and dependable repairs. Our licensed technicians have the tools and experience to diagnose a wide range of problems and get your system back on track fast.

Before we begin any repair, we'll provide honest and upfront pricing along with a clear explanation of the issue. Our approach eliminates confusion and builds trust. And if you're not completely satisfied with our work, we'll make it right-or you don't pay. For homeowners in need of reliable air conditioning services in New Brunswick, our repair team delivers results you can count on.

Day-and-Night Emergency Services

When an AC failure happens outside regular business hours, it can be stressful and uncomfortable. Guaranteed Service is available 24 hours a day, 7 days a week-including weekends and holidays-to provide emergency AC support. Whether your system breaks down in the middle of a heatwave or stops working at night, you'll always be able to reach a live representative.

Energy-Conscious Cooling Solutions

Energy costs continue to rise, making efficiency a top priority for many New Brunswick homeowners. According to ScienceDirect, HVAC accounts for 38% of buildings consumption, equivalent to 12% of final energy. At Guaranteed Service, we help our customers save energy and reduce utility bills by offering high-efficiency AC systems and smart thermostat integration. These solutions provide precise cooling, adaptable scheduling, and remote access via mobile devices.

In addition to installations, we offer energy audits and system upgrades that further enhance performance-like sealing leaky ducts or adjusting air distribution throughout your home. If energy conservation is a goal, our air conditioning services in New Brunswick will help you lower your carbon footprint while boosting overall comfort.

Breathe Easier With Indoor Air Quality Services

While your AC system keeps your home cool, it also plays an important role in maintaining air quality. Pollutants, allergens, and excess humidity can build up indoors, especially when homes are sealed for efficiency. We offer indoor air quality services designed to work in tandem with your cooling system to keep your air clean and balanced.

Our solutions include air filtration systems, UV purifiers, dehumidifiers, and whole-home ventilation options that promote healthier living. Our team will assess your indoor environment and recommend the best tools to support your wellness. Clean air and consistent cooling go hand in hand-and we're here to provide both.

Ductless AC Systems for Flexible Comfort

Ductless mini-split systems are an ideal cooling solution for homes that lack traditional ductwork or for areas like garages, sunrooms, or in-law suites. These systems offer zoned cooling with impressive energy efficiency and quiet operation. If you're looking for more control over how your home stays cool, a ductless system may be the right choice.

Our technicians handle every part of the ductless system process-from selecting and sizing units to professional installation and long-term maintenance. As part of our full lineup of air conditioning services in New Brunswick, ductless solutions give you more flexibility without sacrificing performance.
