Great service and price for the new furnace - John from Global handled our whole experience, contacting us every step of the way. He arrived promptly the next day after initial contact and got the job done two days afterwards.

Had a great experience with this company - their technician was knowledgeable, efficient, and got the job done right. Found the problem with our air conditioning and fixed it quickly and effectively. Definitely recommend them to anyone in need of heating or cooling services.

We had a power outage on Friday evening, but thanks to this company, we got our thermostat fixed by Monday morning. The appointment was scheduled promptly and the technician arrived right on time. They were courteous throughout the process, from booking to completion, and took the time to explain what they were doing. We're glad to have our AC up and running ahead of the hot weather - their price was very reasonable considering the service received.

John was quick to respond to my inquiry, scheduling a same-day appointment within minutes. We've used his services several times over the years and will continue to. He's professional and does excellent work - that's why we'll be recommending him to our friends.

We'd been struggling with a decades-old furnace/cooling setup in our home for far too long. John visited us to assess the situation, and we discussed installing a new system. He suggested Carrier, which we researched together before settling on a bigger unit - from 4 to 5 tons - due to our old system's issues with cooling the house.

They acknowledged a week-long wait for installation, citing high demand, but I wasn't bothered by it. The crew arrived promptly and their representatives were as courteous as you'd expect. However, the installation took longer than anticipated, mainly because it was a sweltering day and working in the furnace's attic made it a challenge.

They adjusted the dampers to improve airflow control after that, which has greatly improved the system's performance. With our new setup, we can now keep the house cool at 78 degrees - something the old system couldn't achieve. One minor issue arose post-installation, but John promptly sent someone over and they fixed it within an hour without delay.

I'm extremely satisfied with this company.

Tech showed up on schedule and was extremely friendly, knowledgeable, and helpful. They quickly replaced my Nest thermostat with my Trane one and had it working in no time. The price was very fair. What I'd like to have is the tech's contact information so we can potentially use their services again in the future. Thankfully, Global is easily accessible via phone call, providing peace of mind for now.

Update: I've had two visits from this company now - both were extremely efficient. The technician arrived promptly and completed the check within 30 minutes. I'm sticking with them for my HVAC needs.

Initially, the technician was excellent. He performed our first home maintenance check and ensured our furnace and A/C units were functioning properly. I appreciated the heads-up call he made before arriving, which allowed me to make arrangements as I work from home. Upon inspection, he replaced a faulty capacitor in the furnace for improved efficiency and identified a potential leak in the A/C unit, topping up the coolant to guarantee it was ready for the summer.

The technician informed me that our units were from the mid-to-late 2000s but were still in good condition, providing reassurance. Overall, I'm grateful for the service.

Global Heating & Cooling stepped in when our furnace was needed most - during a brutally cold winter. Their service was prompt, courteous, and spot on. Although we wouldn't have been thrilled if they'd shown up with a non-functional unit at the time, they delivered top-notch quality and reliability instead.

What's more, they tackled both our heating and cooling systems in one go, which saved us a pretty penny. By doing so, they sidestepped a costly hassle that would've come later - having to remove and reinstall the furnace for the AC installation. We're now enjoying reliable and top-notch heating and air conditioning, all thanks to Global Heating & Cooling's savvy approach.

The price was decent, and more importantly, we saved thousands on labor and permit costs. Overall, we're thoroughly pleased with their work and would wholeheartedly recommend them for any HVAC needs they may have.

We're extremely satisfied with the fantastic service provided by Global Heating and Cooling Services. The entire team was punctual and knowledgeable, happily addressing all our queries.

We wholeheartedly endorse this company for all heating and cooling needs, as well as duct cleaning services. The team genuinely prioritizes customer satisfaction and reputation. They offer high-quality equipment backed by a comprehensive warranty. While we'd give more stars if possible, our experience earns them an excellent rating, and we're grateful for their service.

They also quickly diagnosed and replaced our faulty thermostat with a new one on the spot, resolving all our issues.

We had a major AC breakdown last week, but Global Heating and Cooling Services sprang into action right away. I received a response within 10 minutes, and we set up an appointment on short notice. John showed up on time with several options for our new unit. We opted to replace the old noisy one with a quieter, more efficient model. Just three days later, his team arrived and got us back up and running in under three hours - they even hauled away the old unit as well.

The technicians working with John were also top-notch - knowledgeable, friendly, and great guys to deal with.

We upgraded our furnace, added the AC, and replaced the ducting as it was ancient. The work was done quickly and professionally, and everything is now running smoothly. They even tackled some other old stuff in our utility area that they noticed.

The service was excellent, the people were fantastic, and we'll definitely be using them again.

Joey's expertise shone through - he efficiently fixed our faulty AC during the heatwave by replacing the capacitor. The result: our AC is now working again. The service was top-notch, leaving us grateful for the solution.

We had a great experience with Global Heating and Cooling. They installed our air conditioner and replaced our furnace in one day. The company responded promptly to our questions and offered helpful suggestions for energy-efficient products that would work well in our older home, built in 1963.

The price was very reasonable, especially considering the level of service we received. John and his team were knowledgeable, efficient, and clean. They even cleaned up after themselves in the hallway. John went above and beyond to help us with the duct pressure testing and city permit process, making it a smooth experience for us.

We're extremely happy with our new AC system, thanks to John's guidance on how to use it. What impressed us most was the level of care and patience shown by John and his team.

John's attention to detail and commitment to customer satisfaction are truly impressive. We highly recommend Global Heating and Cooling to anyone looking for reliable home services.
