I was not a service call. It’s just a yearly check up on the air conditioner. I did not meet Thomas personally, but my wife said he was very nice man. you must’ve needed a garden hose for something. I noticed it was moved, but it was wrapped very nicely and put back where where he found it. I appreciate that. overall, we were very pleased with the service. Thank you.
Outstanding
Extremely happy
fantastic technician and service!
Great company to work with! Good communication, availability and the plumbers who came to pull a gas line were professional. Would definitely use their services again.
We received great service and happy with the results!
Tony and Kevin were great, very professional and very knowledgeable- they listened to what I thought was going on, started there and quickly solved the A/C airflow issue. In this day and age and how expensive everything seems to be it was refreshing that Tony seemed very aware of pricing and as a result of their experience and efficiency make the bill very reasonable
Aaron was knowledgeable and extremely helpful
Technicians Steve Gray and Chase were Outstanding in every detail from presentation to knowledge , expertise and commitment to resolving my problem. I am a very please customer and I just need to say Steve and Chase represent your company extremely well. I will continue to be a very loyal customer. Thank you
Xavier and Mike did an excellent job.
We were very happy with the Service! Jacob and his “understudy” showed a very professional and efficient service. Jacob seem to be very experienced, and knowledgeable, and can think outside of the box. For over 20 years every time we had the boiler serviced, louvre was recommended as a solution for the low air supply.. Jacob saw the unused 4 inch dryer duck which is already in place and with minor modification can provide more air, which I thought was a brilliant idea. Highly recommend this team to anyone!
Nicholas from GEM was very informative and fixed our problems and gave good advice. Thank you!
Generator maintenance. Excellent in all respects.
Douglas is terrific!
Orlando and Marcello are true superstars of your business! Polite, very quick at helping me fix my problem with my Plumbing. The whole process from start to finish was handled beautifully thank you so much for making a stressful situation so much easier!
Excellent work on a variety of household electrical needs. Service techs were professional, friendly, and all work done to high standards!
Excellent service! Gem Plumbing was professional, responsive, and arrived on time. They quickly identified the issue with the roof drain pipe, clearly explained the repair, and completed the work efficiently. The quality of the workmanship was excellent, and everything was left clean when the job was finished. I would definitely recommend them to anyone looking for a reliable plumber.
Excellent service with clear explanation. On time, friendly professional communication. Issues resolved with creativity!
Cory was very knowledgeable and respectful.
The technical aspects of the job he explained so I could understand.
Great all around for a large on-demand heating installation project . Very talented team. Very impressed . Will definitely use GEM in the future
I had a great experience with my recent HVAC appointment. David the technician was punctual, polite, and very thorough while performing the annual maintenance of both our heating and cooling systems. He explained what was doing, reviewed the results of the tests that were done and provided estimates for potential future component replacement.

Punctual, professional, polite. Everything was done to my liking and reviewed with me when completed. If you want it done right, call GEM!

Joan handled our house today. Great technician.
Hands down the best service, communication is top notch. My Ac and furnace needed to be replaced and I must say Alecs Reyes and team were amazing, polite and professional and informative every step of the way. I highly recommend Gem. Update I also had them move my electrical panel which was not up to code and was the worst thing they have ever seen lol the team who handled the move was amazing once again fantastic work by the gem team!
Efficient professional and quick service excellent!! Thank you Eric
Devontay Vaz and his colleague did an excellent job servicing our scheduled maintenance on our Heating and Cooling Mini Split system which is part of our Maintenance Plan. They took the time to explain the process from start to finish. They also made sure to explain the future unit maintenance after the summer season, which we found VERY helpful. We have been members of Gem Heating and Plumbing for years now. As always, the technicians were polite, professional, and knowledgeable about their work. With life being busy, Gem always call us as a reminder to make these scheduled appointments. Thank you, Gem Plumbing!!
John is great.

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 Milford

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.

The most common type of cooling system in Milford, 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. For comprehensive air conditioning in Milford, 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 Milford’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 Milford homeowners enjoy targeted comfort and quiet, efficient cooling throughout the summer.
