Steven and Diego arrived to check out our system and were able to get everything up and running. They were professionally, efficient and friendly. GEM Plumbing employees are always top notch!
Two technicians came to assess my minisplit which has been leaking. They spent a lot of time working hard to find an answer which unfortunately ended in needing a follow up appointment with a handyman through GEM, to resolve an issue with my unit. But while the techs were here they really tried very hard to resolve the issue. I give them an A for effort.
New resident needing plumber to improve drainage of bathroom sinks and stop leaky faucets. As first plumber I called did not call me back, I called Gem for help. William and Mark were sent to provide service within 2 hours. Problems corrected after thorough discussion of options and pricing for each. Selected the replacement option for leaking faucets, which resulted in spending more money than anticipated, but they selected good looking faucets from supplier and returned to install them. I elected to enter into a one year contract to secure HVAC service for the year, eliminating the dispatch fee. I am pleased with the new well functioning faucets. Good communication with technicians and office representative, Melissa.
They were both great. They explained everything very well.
The best. Great communication, clear pricing, does the whole job and doesn't leave until everything is handled. I have referred them to several people because trustworthy people are hard to find
Very professional and knowledgeable on what needs to be done
Did a great job
The crew.
Was very respectful of my property and worked very efficiently. The clean up after the work was accomplished was impeccable. I highly recommend them without reservation.
Very responsive to my off-hours request for heating repair on a holiday weekend; technician resolved problem. Communication was very good (updates about arrival time, etc.).
John P replaced a capacitor on my AC unit and got it working again. He had to get onto the roof to reach it which is not easy. I asked John a lot of questions about AC and heating units and he is very knowledgeable and helpful
If I could give Douglas 6 stars, I would. He is knowledgeable, and really cares. Did a great job and made recommendations. Not his first time here and always detail oriented.
Anthony Pena was great, he did great work, very fast on fixing our 1 year old water heater union valve and was very nice
Highly recommended 5 stars all day
We are very pleased with the work Aaron did. He explained everything that was going on as he performed the task. Very professional and polite
Tyler the tech was outstanding. Gem, the umbrella company over Carmines had two scheduling issues but in the end they came out and took care of us. TY.

Very pleased with Gem these past several years!
Joey and David were honest, efficient and kind when fixing my furnace. Joey was and very knowledgeable and shared his knowledge well with David.
Thanks, guys!
Needed an install of a faucet and toilet. The team arrived on time and was able to provide me an overview of what needed to be done and transparency with the pricing. Wrapped it up in a shirt while and looks great!
Great service. On time and reasonably priced. Came out to double check on an issue that was still unresolved at no charge.
I got Steve and his colleague from GEM Plumbing to work on my heat pump. I would highly suggest them. They were very patient with all of the explanations of what was wrong and made sure I understood everything. They also gave me a rundown on changing air filters and educated me on all of the necessary information. Overall, I had a pleasant experience. The entire process, including diagnostics and problem resolution, took less than two hours.

Signs It’s Time to Install a New Mini Split

Ductless mini splits are known for efficiency and reliability, but even the best systems don’t last forever.

It may be time to replace your unit if you notice:

If your energy costs are increasing without changes in usage, your mini split may be losing efficiency. Newer systems are designed to deliver the same comfort using less energy.

When your mini split struggles to maintain consistent temperatures, it can indicate aging components or improper sizing. A new system provides reliable, room-by-room comfort you can count on.

Needing repeated service calls is a sign your system may be nearing the end of its useful life. Replacing an older mini split can be more cost-effective than ongoing repairs.

Older mini split systems may lack modern features like advanced inverter technology or smart controls. Upgrading gives you better efficiency, quieter operation, and more control over your comfort.


How Do Ductless Systems Work?

Ductless mini-splits are all-in-one HVAC systems that have both heating and cooling capabilities. They’re compact, energy-efficient units that take up less space and reduce the need for a separate heater and air conditioner. Ductless mini-splits don’t require ductwork, making them great for homes without ducts, smaller homes, and home additions.

Ductless systems have an outdoor compressor connected to individual indoor units in the rooms you want to heat or cool. Mini-splits draw in warm air from outside, cool it, and then redistribute the treated air back into the space while heat is transferred to the outdoor unit to be removed. In the winter, these systems reverse this process and extract heat from the outside air to bring it indoors.

The Many Benefits of Installing a Mini Split System

Mini split systems offer flexible, efficient comfort without the limitations of traditional ductwork.

They’re a smart solution for homeowners looking to improve comfort, control energy costs, and customize heating and cooling throughout their home. Key mini split benefits include:

Mini splits use advanced inverter technology to adjust output based on demand. This helps reduce energy waste and can lower monthly utility bills.

Each indoor unit operates independently, giving you precise control over temperatures in different areas of your home. You can heat or cool the rooms you use most without conditioning the entire house.

Because mini splits don’t rely on ducts, there’s no energy loss from leaky or poorly insulated ductwork. This makes them ideal for older homes, additions, bonus rooms, and spaces where ducts aren’t practical.
