Signs It’s Time to Replace Your HVAC System

Age: Like any mechanical system, it will fail overtime.

High Energy Bills: Older models are less efficient & will lose efficiency as they get older.

Frequent Repairs: Repairs aren’t uncommon, but if they are required often, the system is likely at the end of its lifespan.

    Can't say enough good about this company. They worked with me on price and they offered a labor warranty much longer than the other companies. They are masters at the craft to as they addressed all the old issues I had with the system that was replaced. The new system is working great. They replaced both my heater and air conditioner and did it all in a day. Appreciated the follow up to see how everything is going as well. Get a quote from Oasis for any hvac project. I'm glad I did.

    This review is long overdue but I have had time to enjoy our new ac and heater that Oasis heating and air conditioning installed a few months ago. We saw one of their ads on Facebook and requested someone to contact us. We contacted a few companies from ads we saw. Oasis immediately stuck out to us because the gentleman who came showed us their license card when we came to the door. None of the other companies did that so it was different but it was also reassuring since we knew we were making a big investment in our home. One of the issues with our previous system was the poor air flow in our master bedroom. Michael was the only one to recommend increasing the vent to help. Instead of just giving us a quote really quick we could tell he listened to what we talked about and was really trying to fix the issues we had with the old system. They weren’t the lowest bid although close but they were nowhere close to the highest either. Overall we felt most comfortable with Oasis. The install was completed in two days and we have used our ac on many occasions since and weak airflow is fixed. I also tested out the furnace the other morning for the first time too. We are thankful to have found this company and have recommended them to a few other friends and family.

    Oasis was able to come out for an estimate the same day that I found them on Google. The guy who came out was here longer than some of the other companies sales people and he explained that they try to do as thorough of an inspection as possible when providing an estimate. He went into the attic to check out my old system while some others didn’t. Given the amount of time he dedicated just for a free estimate I was expecting the price to be high. It was quite the opposite and more competitive than most. It wasn’t the lowest but they quoted me the brand I mentioned and most of all I felt confident they would do good work given the effort they put into the estimate. The install was schedule and completed a few days later and everything is working perfectly. The house cools really quick and the system very quiet. I recommended them to a friend already and am glad I found them.

    I have been needing to upgrade my home air conditioning system for the past few years and have been putting it off. Instead of doing a repair this year I decided to get a whole new system. I interviewed several companies and decided on Oasis. I was somewhat nervous since they are a new company but that quickly went away. They communicated well, finished the job on time and showed me how to use the thermostat. Also they tested the system afterward while they cleaned up to make sure everything worked. I’m happy I gave them the chance. :)

    I found Oasis when looking up someone to replace my AC. They were able to give me an estimate that same day and then install everything even that same week. Everything is working perfectly. Appreciate them being so fast so I could stay cool during the heat wave.

    Got in touch with oasis when my ac unit suddenly went out. They showed up within a few hours and fixed the issue. Unit is still working and price was reasonable. Give them a call if you need help.
