HVAC reviews across the US

Jeff was a fantastic professional for my HVAC job. Very knowledgeable and understanding of the issues with my systems. Great pricing and responsiveness.

Jeff and team from Oasis Cooling and Heating are nothing short of exemplary. I needed to replace my old propane furnace that failed and Oasis provided multiple options that were all priced reasonably. Jeff was straight forward in all his answers and explained terms/situations clearly when needed.

Oasis Cooling and Heating not only has great service but their workmanship is top notch as well. The finished system functions amazing and it even looks great too. You can tell Jeff and his team really care about what they do and they make sure that the systems they install/maintain portrait that. They strive for the 5 star service and they definitely deserve it.

Do not hesitate to contact them for your HVAC needs, you won't be disappointed.

Jeff from Oasis did an awesome job. He installed a new mitsubishi mini split system for my apartment above a garage, and Propane heater for the Garage. He worked with me about many different ways that we could go with to heat and cool those spaces, and how much it would cost in electricity and/or Propane.
He is very honest and doesn't try to sell you things that you don't need. Jeff's work is the best, and his price was several thousand dollars less than the big companies. I highly recommend giving him a call.

Choosing Oasis was a great decision I made. Their quote was best I had received, (one was almost $4000 more for the same equipment) Jeff was very responsive to any text/ calls within minutes. Jeff has a great team that works with him. Very Efficient and very Neat, you would not know they were even there. They ran Into a couple of issues with the way the old system was installed, but Jeff and crew took it all stride, and made everything right. It could have been a disaster. The difference was night and day. Jeff was very knowledgeable about all the equipment that was going to be used. He answered all of our questions, very thoroughly. Kudos to his team:Ian and Sam also. You will not be disappointed if you choose Oasis for all Heating And Air conditioning needs.

Extremely professional, timely, and respectful in all aspects of his business. Jeff made the process seamless and made sure all our concerns were heard before doing any work. Will be working with him again in the future for all my cooking and heating needs!

I couldn’t be happier with my choice! I contacted several contractors to compare options for replacing my old oil furnace and aging AC unit. Oasis stood out from the start. Jeff was professional, communicative, and on time for every step. Pricing was competitive, and I feel I got top-quality products with a full Bryant (Carrier) system for the indoor and outdoor components.

They installed a 96% efficiency propane furnace (80K BTU) , a cold-weather heat pump (horizontal discharge), crossover coil for a dual-fuel solution, an air filter, and a whole-home humidifier—just in time for winter. The system layout is clean, and all work was done to a high standard. Jeff even coordinated everything: suppliers, inspections, oil tank removal, and water heater installation.

I highly recommend Oasis for anyone looking for quality work and great service!

A quick service call as a second opinion turned into my permanent go-to for all things HVAC. No pressure, just honest facts.
Replaced my Furnace in 1 visit a week later. Very professional and clean installation. Pricing for a Bosch unit was 35-40% less than the no-name brand quoted by another HVAC company driving flashy trucks.
A sincere thank you for such excellent service.

I never write reviews but I just had to Oasis Cooling and Heating after my experience because it was simply superb!

We were looking to add mini splits or central air to our home but there was so much to consider. Jeff talked us through everything we needed to know with immense detail! He is an amazing person and truly wants the best for his customers. He took his time to ensure we were choosing the right option and provided his expansive expertise for us. He even urged us to compare prices to ensure we were getting the best deal.

Once we settled on an option, he kept in consistent communication until we found a date that would work for installation. He was able to sneak us in before the holidays to make sure we were eligible for a national and state rebate. He did an AMAZING job and we could not be more happy with the care, organization, and thought that went into everything. He installed our central air in two large room within one day! I couldn’t have asked anything better from the experience.

I can’t recommend Jeff and Oasis enough for all of your HVAC needs. They’re the best and we’ll be using them in the future. Thank you!

I needed prompt service as I had no heat during a cold snap. I told Charlie I needed a new furnace installed asap and he made sure it was done the day.

I called on Monday and they were able to fit me in on Wednesday. They arrived on time, were pleasant, efficient, and clearly explained the problem with our A/C system. I will absolutely call them again.

Very easy to work with and the staff was extremely professional. They replaced a freon based AC/heating unit utilizing today’s improved technology. From start to finish it was a pleasure working with Marshall Mechanical.

Charley came out promptly when we asked, spec'd the project, gave us a quote quickly and the work was scheduled within 10 days. Guys onsite for the project did a great job, moved vents just as needed and actually made the return air duct vastly quieter. Excellent work all around. Many thanks.

Charlie Marshall and his team were responsible for the installation of many HVAC systems 5+ years ago for a builder that owned the rights to a cul-de-sac community in southern New Hampshire. I happen to be one of those homes. Charlie and his team installed a high efficiency HVAC system in an uninsulated attic which should never have passed inspection being that those systems require double ventilation or an insulated attic. I have been unable to find a reputable company to service this unit in all those years because of parts that were used that have been recalled or the fact that the system does not meet compliance. I have called Charlie Marshall on his personal cell phone many times over the years and have not received a phone call to discuss this matter.

Therefore, I find this review to be extremely appropriate to give buyers a buyer. Beware of what you are purchasing and installing in your home since this individual doesn’t seem to install things to code. This might be a one off, but Charlie had every opportunity to fix the issue and he did not.

Charlie was extremely responsive with our family when our system failed and needed to be replaced with incredible urgency in frigid weather. He was both professional and kind. Highly recommend!

As new homeowners, we have had a lot to learn and Charlie and Joey have been incredibly helpful. They’ve addressed our issues thoroughly and carefully and have answered questions clearly. We’ve also been impressed with how quickly they’ve come out (48 hours at most). Highly recommend!

Charlie and his team really came through for me and my family, Friday night sometime our furnace started tripping the rollout switch after many phone calls I was given the number for Marshall Mechanical , Charlie made a trip over Saturday evening to confirm our fear that it was time for a new furnace.
We were given options and a clear explanation of what we’d be getting and then first thing Monday morning they swapped our unit out .
Very friendly and professional and left zero mess .
I hope to only need their services for routine maintenance now.
Thanks guys Merry Christmas

When my AC had a leaky coil and a large service company wanted to change the entire system including outdoor condenser even though nothing s wrong with it, i found Kody and Jordan not onky knowledgeable about the parts that need replacing but they came and did the job 2 days later. Now i am a forever HVAC customer because of their professionalism, honesty and efficiency. Thank you JP.

I could not be happier with the service I received from JP HVAC. Friendly, knowledgeable, thorough and reasonably priced. We have had issues with our system caused by another company servicing it and compounded issues by a second company. Jordyn and his fellow worker went through our system, got us back up and running and corrected multiple wiring issues with our thermostats and replaced a flaky circuit board. This company will be our go to for any issues and for maintenance of our system.

Jordyn and Kody found the solution of a shoddy install from another company in the area. Very professional, and were in constant contact about shipping of the new heat exchanger. They also put on a new roof cap, fixed the air flow rate, correct install the exhaust.
Very happy with this company and feel much safer seeing the old scorched heat exchanger leave me house.
I will be calling, back for any hvac needs.

These guys are awesome. I had no heat last nite and he came right out first thing this morning. Ill recommend them to everyone i know. Thank you so much!!!

Jordyn and Koby diagnosed a long standing problem with radiant floors and solved it very patiently. Then I had them install an Aprilaire whole house steam humidifier to solve a humidity problem. They did it fast, neat and were extremely knowledgeable about how to optimize effectiveness. They’re honest, patient and professional. I would recommend them in a second!
