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!

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.

Highly recommend Jeff! He was tied for the best quote out of 4 I got for the install. He and his team did a great job doing a nice and thorough install that looks good in the house. We did the install a couple months ago and recently had an issue that ended up being a faulty wireless module in the unit. Jeff responded and was at our house the same day to help fix it.

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.

Jeff was so kind and thoughtful during this process. He genuinely tried to repair our system before recommending a replacement. When he came to install, it was fast, clean, and he was fun to chat to as well! Couldn’t recommend enough! My dog misses him already.

Jeff was awesome. He did what he said he was going to do. They we are very thorough and honest, they didn’t try to oversell us. He installed a brand new mini split in one day! It works great, we are very happy with the product.

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 cooling and heating needs!

Cannot recommend Jeff with Oasis Cooling & Heating enough. We have been without a furnace for 14 days due to the holiday and lack of communication with another company. When we contacted him, he worked us into his schedule immediately to make sure we had heat before this cold weather. Jeff was extremely knowledgeable, reliable, and professional. 10/10 recommend calling him with any heating and cooling needs.

Common Questions

Frequently asked questions

Do you offer emergency HVAC service?
No-heat and no-AC calls get priority. We'll always try to get you on the schedule the same day, and if it's after hours, call anyway — we'd rather know than have you wait until morning.
Are you licensed and insured?
Yes, fully licensed and insured. Oasis is family-owned and locally based — not a franchise or a private-equity rollup, so the person who quotes the job is the same person who's accountable for it.
What towns do you serve?
All of Rockingham County, NH — from Salem to Portsmouth. See the full list of towns we serve below.
How do I know if I need a repair or a full replacement?
We'll always try to repair before we recommend replacing anything. If a system's genuinely at the end of its life, we'll tell you plainly why — and what a replacement would actually cost — instead of pushing an upsell.
Can you install a mini-split in a home without existing ductwork?
Yes — that's exactly what ductless mini-splits are built for. They're a common fit for additions, converted garages, and older homes that were never built with central ductwork.
How often should I have my system serviced?
Once a year, ideally before the season that's about to stress it — heating systems in the fall, cooling systems in the spring. A short annual tune-up is what usually prevents the 2am no-heat call.
