Oasis Cooling and Heating describes itself on its website as a small family business providing HVAC services. Its NH HVAC licence, MBE2501716, is active on the state registry, held by Oasis Cooling and Heating, LLC. A recent customer says Jeff recommended and installed a Bosch propane furnace and heat pump to replace an ancient oil burner, did all the gas piping along with new exhaust and intake piping, replaced the aging flexible ductwork in their attic and rewired the panel on their other furnace. Another recent customer says Jeff's quote was tied for the best of 4 they got, and that when a faulty wireless module caused an issue a couple of months after the install, Jeff was at their house the same day to help fix it. A third recent customer says a service call for a second opinion led to a furnace replacement in one visit a week later, with pricing for a Bosch unit 35-40% less than a no-name brand quoted by another HVAC company. In a 2025 review, a customer replacing an old oil furnace and aging AC unit said Oasis installed a 96% efficiency propane furnace, a cold-weather heat pump, a crossover coil for a dual-fuel solution, an air filter and a whole-home humidifier. That 2025 customer said Jeff coordinated suppliers, inspections, oil tank removal and water heater installation. In another 2025 review, a customer said Jeff installed their central air in two large rooms within one day and fit them in before the holidays so they were eligible for a national and state rebate.
Jeff recommended and installed a Bosch propane furnace and heat pump to replace an ancient oil burner. The new system is fantastic in both heating and cooling our home. He did all the gas piping, along with new exhaust and intake piping. He also replaced all of the aging flexible ductwork in our attic, and rewired the panel on our other furnace. Everything about working with Oasis was simply excellent, from the quotes through system design and installation. If you want a great job of the highest professional calibre and a reasonable price, look no further - Oasis is truly excellent!
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.
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 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!
