Very good experience

Angela Freitas Ortiz

After calling several places with two no shows, the moment I called Endless Energy, I felt like I was in good hands. Jake had THE BEST customer service skills and really worked with me to help my situation. This something you don't see that often anymore. My central air cranked out during the heatwave, and he was able to get me an emergency appointment since I have a little girl with complex medical needs who is more compromised in these situations. That same stellar service continued the moment Eydin and Pedro walked through my door to assess and fix the problem. They were pleasant and skilled. They took the time to explain each of the issues, showing me videos of before and after. "Exceptional" service from the first call to completion. 5 Stars and High Five to this Team and your company. You are doing something RIGHT.

Very helpful staff on servicing my 8-year old heat pump unit. The whole house heat pump system they installed 2 year’s ago is working well even though that heat wave we just had.

Mark was very informative and easy to communicate with

I discovered that my central AC unit started leaking water in the basement in the afternoon on 6/24/2025, when it was100 degrees outside. Endless Energy answered my phone close to 5 PM and called me back to confirm my appointment just before 5:30 PM. They were courteous, responsive and reliable.

Eydin arrived in about an hour. He was polite, professional and meticulous. Throughout the process, he explained his diagnosis and solutions he would try. After cleaning the main clogged pipe, he carefully examined the other parts of the central air unit to see if they were leaking. He also gave me advice on getting fans to dry the floor.

I appreciate Endless Energy for their quick response and professionalism in both communication and performing the repairs. Thanks to Eydin and the dispatcher who helped me make the appointment (Sorry I forget your name but you are both awesome!)

This is in appreciation of Garrett, who came out this morning on the hottest day of the year.
First of all, I am a big fan of this company. I had mini splits installed last summer and everyone at this company from the sales associate to the techs to the schedulers, is a pleasure to work with.
Most recently, I made my first service call after about ten months with our new units. Nothing was wrong with them, but they were acting like they were being controlled by aliens. I knew it had to have something to do with the integration system - Flair - and I would not be able to navigate this on my own.
By the way, this is during a massive heatwave. Do they make me wait? They do not. I get a service call immediately, orchestrated by the very talented Alex (sorry, I also write theater reviews).
You know how you always have a window? Well Garrett arrived at the beginning of the window. He agreed it was the Flair pucks being naughty, and we both thought it was going to be a simple fix.
Garrett fixed it, and it was complicated, but he never broke a sweat. He didn't indicate frustration, just quietly kept working and answering my questions all the while. People like Garrett is why professionals exist.
He fixed all the issues - meaning, ones I didn't know I had - with the Flair and those silly pucks and gave me a tutorial afterwards and it was like the skies cleared up and I understood the Flair universe.
Another Happy Endless Energy moment. Thanks, Garrett.

Edyin was great! Quick fast service. Our AC at our salon unit broke right before this heat wave. Resined fast with availability next day. Highly recommend .

HVAC Installation

A new HVAC system is a significant investment, but it’s one that pays off in comfort and energy savings. At Endless Energy, we help you choose the best system for your home, balancing efficiency, performance, and budget.

We install top brands like Mitsubishi®, LG®, and Bosch®, known for their durability and energy-efficient designs. Whether you need a furnace, central air conditioning, or a ductless mini-split, we ensure flawless installation and provide guidance on how to maximize the performance of your new system.

HVAC Repair

Is your system making strange noises? Or maybe your house isn’t staying as cool or warm as it should be. These are signs that your HVAC system might need repairs.

Our expert technicians can quickly diagnose and fix any issue, from minor malfunctions to more complex repairs. We believe in transparency—you’ll know the cost upfront, and we’ll provide options based on your needs. Don’t let small problems turn into costly repairs down the road.

HVAC Maintenance

Routine maintenance is crucial for extending the life of your HVAC system. By catching potential problems early, we help you avoid costly repairs and ensure your system runs efficiently year-round.

Our comprehensive HVAC maintenance plans include:

Inspecting and cleaning filters
Checking thermostat settings
Lubricating moving parts
Ensuring proper airflow
Testing safety controls

These simple steps go a long way in preventing breakdowns and keeping your energy bills low.

Ductless Mini-Split Systems

Looking for an efficient way to cool or heat individual rooms without the hassle of ductwork? A ductless mini-split system could be the answer. These systems are perfect for older homes, room additions, or spaces where extending ductwork is impractical.

Our ductless systems offer flexibility, allowing you to control the temperature in specific areas of your home. Plus, they’re energy-efficient and easy to maintain. At Endless Energy, we install, repair, and maintain ductless mini-splits, ensuring they perform at their best.

Indoor Air Quality Solutions

From eliminating allergens to controlling humidity levels, we can improve your indoor air quality, helping you breathe easier and live healthier.

We know that HVAC emergencies don’t always happen during regular business hours. That’s why we offer emergency HVAC services to ensure you’re never left without heat in the winter or air conditioning in the summer.

Our technicians are available 24/7 to address urgent repairs and get your system back up and running as quickly as possible.

HVAC Maintenance Tips for Homeowners

Want to keep your HVAC system running smoothly between professional check-ups? Here are some simple maintenance tips you can follow:

Check your thermostat settings: Make sure your thermostat is set to the correct temperature and consider upgrading to a programmable thermostat for better energy control.
Clean around your outdoor unit: Remove debris, such as leaves and dirt, from around your air conditioning unit to ensure proper airflow.
Inspect your ductwork: Leaks in your ductwork can cause energy loss. Check for visible gaps or hire a professional to seal any leaks.
Schedule regular maintenance: Routine maintenance by a professional ensures your system is operating at peak performance and helps prevent costly repairs.

By taking these simple steps, you can prolong the life of your HVAC system and ensure it operates efficiently year-round.
