Common Air Conditioner Problems

There are several issues that can cause your air conditioner to malfunction or stop working altogether. Some of the most common problems include:

  • Refrigerant leaks: Low refrigerant levels can cause your AC system to work harder and less efficiently, leading to higher energy bills and potential damage to the compressor.
  • Clogged air filters: Dirty or clogged air filters restrict airflow, forcing your AC to work harder and potentially causing it to overheat.
  • Faulty thermostat: A malfunctioning thermostat can cause your AC to cycle on and off frequently or not turn on at all.
  • Drainage issues: A clogged condensate drain line can cause water to back up into your home, leading to potential water damage and mold growth.

If you notice any of these issues or your AC system isn’t cooling your home effectively, it’s essential to call in a professional for air conditioner repair as soon as possible.

Customer Reviews

Oasis has always been great to work with and their staff are quick and efficient if issues arise. When our air conditioning broke down during the heat of the summer, they provided a quick replacement at a competitive price. Their staff are always extremely kind, respectful, and knowledgeable.

Sam C.

Oasis was incredibly responsive and efficient! My call to them on a Friday night during a cold spell was returned within 10 minutes and he scheduled a tech to come to my home at 7 the following morning. At 7 the tech was there, examined my furnace confirming that a new motor was necessary. He searched for the part, sent a quote and returned with the motor by noon the same day to install it. You can’t beat that!!! I will be using Oasis for all my future furnace and A/C needs.

Gayle V.

I called Oasis this morning because my furnace was not working. Within 20 minutes their technician, Danny, arrived. Danny was able to assess the situation, provide an immediate fix, and even commit to returning Monday morning to provide additional services needed. Danny was friendly, informative, professional and FAST! I am thankful I called Oasis for my immediate heating needs and that Danny was the technician who arrived. Top notch service! Highly recommend.

Megan R.

Danny and the folks at Oasis got us a great deal on a new furnace and AC. The install took about 4 hours, and they were also super responsive throughout the process. It was about as good of an experience I’ve had with an HVAC company. I’d highly recommend!

Brian C.

The folks with Oasis showed up right on time and replaced my entire furnace and condenser in about 4.5 hours. I had just redone my laundry room where the furnace is and they took great care not to damage anything. Overall very happy with the service and very happy with how respectful the installers were.

Josh D.

Oasis is great! My furnace is almost 30 years old and for a reasonable price they were able to do the repairs. First Danny came to evaluate. He showed me what was wrong. They had to order the necessary parts to fix it. Today Hani and Fernando came to do the repair. They were efficient and courteous. I will definitely use Oasis in the future.

Emily H.

I have been using Oasis since 2019. They are reliable, efficient, and their prices are reasonable. The customer service is amazing. Every tech I’ve had come out is knowledgeable, friendly, and professional. The owner, Mike, is hands on and works with you every step of the way. Highly recommend Oasis.
Services include: furnace and AC replacement; annual maintenance.

Nicole U.

I had a great experience with Oasis. Our furnace had issues on Thursday night and Oasis came at 7am the next morning, and we found out we needed a new one. They provided all the necessary information to our condo building so we could get an emergency replacement on Saturday morning. Within 36 hours we had a brand new furnace and the installation team did a great job communicating on their work and how to use the furnace. The owner, Mike, and his team are great and I really appreciated the attention they gave to this matter. I would highly recommend and will only go to them in the future.

Shane H.
On time, efficient, reasonably priced, and a nice knowledgeable technician.
The Oasis team could not have provided a better experience. I’ve now worked with them a number of times on annual tuneups, installing a new AC unit, and some minor ductwork in our buildings storage room. A+ all the way. Really appreciated the transparency, ease to work with, and pricing. Absolutely recommend!
Response from the owner:Thank you, Shawn, for your fantastic review! We're glad to hear that you've had such positive experiences with our team and appreciate your kind words about our transparency and pricing. Your recommendation means a lot to us!
Response from the owner:Thank you, Kevin, for the 5-star rating; we truly appreciate your support!
Great service, arrived on time and the AC techs very knowledgeable. I have used their services in the past and will continue to use them in the future.
Response from the owner:Thank you, Ricardo, for your positive feedback and loyalty; we're glad to hear our techs provided you with knowledgeable service and look forward to serving you again in the future!
We are very happy with choosing Oasis for our hvac seasonal maintenance and service. Service tech Naem is very pleasant and thorough. We highly recommend Oasis.
Response from the owner:Thank you, Gregory, for your kind words and recommendation; we're glad to hear you had a great experience with Naem!
Oasis was great from start to finish! Had to get a full system replacement and Mike the owner came out quickly and was very fair in the assessment. We had some competitive bids but trusted Mike and his team as he expressed a desire to see things done right not just done.
Response from the owner:Thank you, Mike, for your kind words and trust in our team; we're glad to hear you had a great experience from start to finish! Please don’t hesitate to reach out anytime, for anything!
Oasis Heating & Cooling did a great job installing a new AC system and a new furnace for me. Their pricing was fair, and they were professional and prompt throughout the process. Hani was excellent as the point person for the entire project, and Fernando, Damir, and Michael did a great job installing the system. I strongly recommend Oasis Heating & Cooling.
Response from the owner:Thank you, Aaron! We appreciate your kind words and are glad Hani, Fernando, Damir, and Michael could provide you with a great experience. Your recommendation means a lot to us!
Response from the owner:Thank you, Matt, for your 4-star rating; we appreciate your feedback and support!
I have had very good experiences with Mike and his team over the years at Oasis HVAC. A few years ago when we first moved into the house, another HVAC company provided maintenance to the system while disconnecting the overflow drain switch on the AC coil pan. Therefore the unit ran for days and flooded our downstairs DEN. Oasis saved the day, reinstalling the switch and fixing the system. Now our old system is 19 years old and makes no sense to pay $1,000 to fix it so yesterday we decided to replace it.

Mike came out to look at the old central air and heating furnace unit which is in the upstairs of our bungalow. Seated horizontally, it was going to take a lot of work to get the old unit out and the new unit in. We selected the American Standard (highest rated in the industry a.k.a. Trane) 80K BTU 2 stage furnace/central air and an American Standard 3.5 ton 13 seer A/C unit outside. The team of 5 guys came out to install it just 4 days after signing the contract promptly at 7:00am and completed the entire job at 2:30pm. They had originally thought it would take a day and a half. I also elected the annual maintenance which they come out 2 times per year and will also cover labor, along with manufacturer's hardware warranty for 10 years.

The units are EXTREMELY quiet, you cannot even hear them run. Especially being outside and entertaining the patio. My electric bills are also expected to decrease significantly. The 19 year old previous system originally purchased from Sears was costing an additional $400/month just to run in the summer to to mention the old freon was $220.00 per pound.

I am VERY satisfied with Oasis HVAC, quality product, quality service, attention to detail, professional and courteous. They also don't change extra for after hours emergency maintenance and have been easy to reach in the time of need and arrive at the house in 1-2 hours after creating an appointment.

Oasis HVAC comes highly recommended from a highly satisfied customer.
Response from the owner:Thank you, Keith, for your wonderful feedback and for trusting Mike and our team at Oasis with your HVAC needs over the years; we're delighted to hear about your positive experiences and are thrilled that you're satisfied with your new system! We look forward to continuing to work with you!
Our technician Chris was prepared and easy to work with, as we had two jobs for him. After an estimate, he worked us into his schedule for the next day. He was on time each day and very efficient in how he completed his work. These were both plumbing repairs.
Response from the owner:Thank you, Rick, for your kind words about Chris and his efficient work on your plumbing repairs; we appreciate your trust in us and are glad we could meet your needs! We are here for all of your HVAC and Plumbing needs!
Fantastic service from Oasis! Joe and Dan cleaned and checked our air conditioners today and gave me a complete report on their condition. They were prompt, friendly, courteous and very efficient. So happy we found Oasis, we were so tired of being lied to and ripped off by the larger companies.
Response from the owner:Thank you, Mary, for your kind words and for recognizing Joe and Dan's hard work; we're glad you chose Oasis and are happy with our service! We are here for all of your HVAC and Plumbing needs!
Quick service and top level customer service.
Response from the owner:Thank you, Matthew, for your kind words; we truly appreciate your feedback!
Response from the owner:Thank you for your 5-star review!

Response from the owner:Thank you, Smith, for your kind words and for recommending Oasis; we're so glad to hear that Mike and the team have provided you with professional and dependable service throughout the years!

Response from the owner:Thank you, Joseph! We're glad to hear that Damir and Amir provided thorough service for your A/C unit. Your satisfaction means a lot to us! We're here for all of your HVAC and Plumbing needs!
Love Oasis. I use them for yearly maintenance. They’ve installed a new A/C unit and furnace in past couple of years and just had them put in a new water heater. Chris came out for the job. Great service, very knowledgeable, and efficient. It’s nice to have a place to go to that you can trust with major home issues. I highly recommend!
Response from the owner:Hello Sado, our staff always enjoys reading reviews such as the one you left us! It lets us know we are making customers happy and doing something right! Please let us know if there is anything else you need.
I had the most wonderful experience with the team at Oasis Heating & Cooling. Today I had Damir, Amir, Anel, and Vaha out to replace a part in my unit. They were efficient, professional, kind, and completely fixed my issue.

I moved into my condo in April 2021 and my air conditioner has never worked correctly until now. I replaced the entire unit in 2021 with a company that is now out of business. Even that new unit did not work right. I finally did my research and found Oasis. I can’t stress enough how wonderful this company and specifically this team has been to work with. I will be calling Oasis for every future problem and will recommend them to everyone I know. Thank you Damir, Amir, Anel, and Vaha!
Response from the owner:Thank you, Libby, for your wonderful feedback! We're so glad to hear that Damir, Amir, Anel, and Vaha could resolve your issue and provide you with such a positive experience. We appreciate your trust in Oasis and look forward to assisting you with any of your HVAC and Plumbing future needs!
Response from the owner:Thank you, Brandon, for your 5-star review! We truly appreciate your support and look forward to serving you again. We are here for all of your HVAC and Plumbing needs!
Response from the owner:Thank you for your 5-star review!
Had an excellent experience with Oasis! Chris was incredibly pleasant, highly knowledgeable, and quick to respond... He diagnosed the ejector pump issue immediately and had it repaired in no time. Chris was professional, courteous, and made sure everything was spotless before he left. I highly recommend Oasis for any Plumbing or HVAC needs!
Response from the owner:Thank you for your wonderful feedback! We're delighted to hear about your experience with Chris and appreciate your recommendation for our Plumbing and HVAC services.
Fantastic service. Chris was very knowledgeable and efficient. He will be my go to plumber going forward.
Response from the owner:Thank you, Steven! We're glad to hear you had a fantastic experience with Chris; his knowledge and efficiency make a great impact. We appreciate your trust in us for your plumbing needs!
We highly recommend Oasis for their excellent service. There was no attempt to sell services or equipment we do not need
Response from the owner:Thank you, Lisa, for your wonderful recommendation and kind words about our service; we truly appreciate your support and will pass along your words to your technician Naem!
Henry & Omar did a fantastic job. They were quick and clean.
Response from the owner:Thank you, Michael, for taking the time to leave such positive feedback! Please don't hesitate to reach out for all your HVAC (and plumbing!) needs!
Service is always top-notch, on time, knowledgeable, and open to questions when needed. I enjoy having Naem come. He knows what he is doing and is familiar with my furnace and with the air-conditioner as well. He is a pleasure to interact with when he comes. It is easy to see that he enjoys his work and is a great representative for Oasis both professionally and personally.
Response from the owner:Thank you, Pamela, for your kind words! We're glad to hear you enjoy Naem's service and appreciate his expertise and friendly approach. Your satisfaction means a lot to us!
Response from the owner:Thank you, Joseph, for your 5-star review! We appreciate your support and are glad you had a positive experience.
Oasis Heating and Cooling have serviced my HVAC systems for many years. They have been an excellent company for us. This past winter our furnace went out late on a very cold Saturday night. We called Oasis at 10pm; they offered to send out someone that evening or we could have them come first thing in the morning. We opted for early Sunday morning - Damir was at our door at 6:30am on Sunday morning. He fixed the unit and restored our heat.
This past week one of our 12 year old AC units stopped working and we contacted Oasis. They sent Damir and his son to check out the unit. After determining the problem and discussing repair vs replace we opted replace. They had the new unit in place and working two days later.
Oasis has a wonderful preferred service program that provides discounts for customers who sign up for the annual check up and cleaning service on the heating and cooling units. It saved us $500+ on the new AC unit!
If you want an HVAC company that answers the phone, shows up on time, has very knowledgeable and skilled technicians, and genuinely values and takes care of their customers this should be your company.
Thank you Oasis. J George
Response from the owner:Jacquelyn, it was such a pleasure working with you! We appreciate your loyalty and kind words and will be sure to pass them along to Damir and Amir. Thank you and we look forward to working with you again!
I was going pleased with the work performed by the Oasis Heating and Cooling technicians. They did a great job installing a new furnace and air conditioner. The price was reasonable and they used high quality components. Also appreciated they cleaned the work area thoroughly after the job was done.
Response from the owner:Thank you, Manish, for your kind words about our team and the quality of their work; we're glad you were satisfied with the installation and the cleanup! Never hesitate to reach out for all of your HVAC and Plumbing needs.

I have been using Oasis for the four years I have lived in this home. What I know is they are always on time for appointments, and their techs are considerate of your home, pets and you the customer.
They do everything well from a spring tune up to installing a new condenser unit. Haani has been here several times, each time conducting himself very professionally while having completed knowledge of HVAC systems. One time even the owner Mike came when the weather was very hot and they were very busy.
Skilled techs, and fair pricing

I’ve worked with dozens of plumbers over the years in both residential and commercial real estate.

He is the best there is.

We’ve used him for larger jobs too, water heater, etc.
