Davontay was here today to check out our mini-split system for cleaning. He was very knowledgeable regarding these systems and determined that the deep clean could wait a bit. He also gave me some information about an air cleaner that attaches to the mini-split unit. He is a super nice guy to deal with.

Power surge from winter storm fried everything! They came so fast, and I was a new customer then. I was so impressed I bought the service contract they offer-as I knew there was going to be more required, and they do plumbing and heating, too. This time the replaced my entire electric (fuse) box. Day long project. I like that I get the same service technicians, and they have all been amazing. They follow up on everything, too. 👍🏻

How to Know When You Need a New Air Conditioner Installed

Understanding the signs to install a new AC system before it breaks down can save you from serious frustration and discomfort during the hottest days of the year.

Here’s when we recommend considering a new AC installation.

You have an ideal temperature you’ve set on your thermostat, and your cooling system should be able to reach and maintain it consistently throughout your home. When certain rooms feel warmer than others or your system runs nonstop without keeping up, it’s a clear sign your air conditioner may be losing efficiency.

Over time, this can lead to higher energy bills and reduced comfort, making a new AC installation the best long-term solution for your home.

When your system turns on and begins a new cycle, you may hear your air conditioner turn on and produce a gentle hum; that’s normal and doesn’t signal issues. When you start noticing loud bangs, rattles, or grinding sounds, though, it’s often a sign that something isn’t working as it should.

Unusual noises can point to wear and strain within the system, which may worsen over time. If your AC is getting noisier with each cycle, it’s likely time to consider replacing it with a newer, quieter, and more efficient model.

Energy bills typically climb as system efficiency drops. This can happen over time due to wear and tear or system aging. Your technician should inspect your system and determine the cause and extent of the issue.

New air conditioning systems are designed to operate far more efficiently, using less energy to deliver better cooling performance. Upgrading your AC can significantly lower monthly utility bills while providing more consistent comfort and peace of mind for years to come.

Air conditioners typically have lifespans of around 15-20 years. As they age, they naturally become less effective and efficient. If your air conditioning unit is beyond 20 years of age, having it replaced with a newer model can save you money on both energy and repair costs in the long run.

Modern systems are built with advanced technology that improves cooling performance while using less power. Replacing an outdated unit not only enhances comfort and efficiency but also gives you the reliability and peace of mind that comes with a brand-new, warranty-backed system.

We Install All Types of Air Conditioners in Boston

GEM is here to help your home stay at the right temperature all summer long, no matter what type of system you count on to do so.

Here’s a look at the types of air conditioners we install:

The most common type of cooling system in Boston, central air conditioners are extremely reliable and effective. No matter how high the outdoor temperatures climb, central AC systems deliver consistent, even cooling throughout your entire home. They’re designed to maintain comfort across every room while keeping humidity levels in check.

GEM installs and services high-quality central air systems that are energy-efficient, durable, and tailored to your home’s layout.

Installing a heat pump is an energy-efficient way to keep your home cool during Boston’s hot summer months. Instead of generating cold air, they move heat from inside your home to the outdoors, maintaining a comfortable indoor temperature with less energy use.

The AC technicians at GEM can install modern heat pump systems designed to provide reliable, consistent cooling while keeping energy costs low.

Ductless mini-splits offer flexible, efficient cooling without the need for traditional ductwork. They’re perfect for individual rooms, additions, or homes where installing ducts isn’t practical, delivering precise temperature control wherever you need it.

GEM provides expert ductless mini-split installation and service, helping Boston homeowners enjoy targeted comfort and quiet, efficient cooling throughout the summer.
