Why is your AC blowing warm air?

Aug 22, 2019 | Cooling

ESSEX August 22, 2019 —

Summer is in full swing and we all rely on the comfort of our homes to provide much needed respite from the heat. This is when we count on our air conditioners the most. If you’ve been asking yourself, “Why is my air conditioner blowing warm air?” here are some possible explanations:

Thermostat

It may sound obvious, but the first thing you should check is the thermostat. If your AC is blowing hot air, the thermostat may have been accidentally set to “heat.” If this is the case, it’s easy to fix on your own. Simply flip the thermostat setting back to “cool” and see if the air conditioner begins to blow cool air again.

The Fix: Check the thermostat and make sure it is set to “cool” and at the proper temperature. If it needs new batteries, replace them. During the cooling season, we recommend setting the thermostat to around 78 degrees Fahrenheit and 7-10 degrees higher while away from home.

Circuit Breaker

After checking the thermostat batteries and setting, make sure the HVAC system has power by checking the electrical panel. HVAC units require a lot of power to run. When there is too much power demand, the circuit breaker may shut off power automatically as a safety precaution.

The Fix: Locate your electrical panel and look for a tripped breaker or blown fuse. To turn power back on to the unit, flip the breaker completely off (opposite direction of all the other breakers), and then flip it to the “on” position. If you have a blown fuse, you will need to replace it. This may also be a good time to label all of your circuits for easy reference the next time there is an overloaded circuit.

Evaporator Coils and Air Filter

Although air filters have nothing to do with air temperature, a dirty air filter can lead to a dirty evaporator coil. When the evaporator coil gets clogged with dust and debris, there may not be enough free airflow to allow for proper cooling operation. You may think that frozen means cool air, but the frozen coils actually impede the flow of cool air, which can lead to warm air flow from the running motor instead.

Air filter replacements should be completed by the owner every 30-60 days, depending on the climate, filter type, and household. We recommend setting a monthly reminder to check the condition of your air filter at the start of every month.

The Fix: If your evaporator coil is frozen, turn the unit off and change the air filter. Wait until the unit has thawed before turning it back on again. If the coils freeze up again,  you may have a refrigerant leak or a problem with the compressor. Turn the unit off and immediately call Contemporary Air Systems.

Condenser Coils (outdoor unit)

Just as the indoor evaporator coils need free airflow, so do the outdoor evaporator coils. That’s why we recommend you maintain a minimum 2-foot clearance around the outdoor condenser unit at all times.

The Fix: If your outdoor unit is clogged, turn off the unit at the source. Then, remove the larger items with gloved hands and rinse off the smaller debris with your garden hose.

Remember to schedule a professional air conditioning tune-up a at the start of every cooling season. In addition to professional cleanings, it’s a good idea to periodically check the outdoor unit and clean it yourself when necessary.

Refrigerant

One of the main causes of a malfunctioning air conditioner is low refrigerant. If you have a worn service valve, loose joints, or poor assembly, you could have undercharged or overcharged refrigerant.

The Fix: Refrigerant (aka coolant) is highly dangerous. Never try fixing refrigerant problems yourself. The best way to prevent refrigerant leaks in the first place is to schedule annual air conditioning tune-ups before the cooling season begins. If you do notice your AC blowing warm air, hissing/gurgling noises, or ice on your refrigerant line, act quickly. The sooner you respond to under or overcharged refrigerant the better. Contact Contemporary Air Systems as soon as possible.

Additional Summer Air Conditioning Tips:

  • Keep your thermostat at 78° while at home and 7-10 degrees higher while away.
  • Use your ceiling fan to feel around 4° cooler.
  • Prevent moisture problems with proper ventilation.
  • Sign up for our Home Comfort Club so you never forget annual tune-up appointments.
  • Set reminders to check your air filter every 30 days.
  • Keep doors and windows closed when running the air conditioner.
  • Clean and dust your home regularly.

From the first time I contacted Rick the owner who is hands on and not a salesman as he is interested in providing you with only what you need, which was very refreshing. I solicited 5 different estimates and Contemporary Air Sys. was the most competitive, easiest to work with, had great reviews, and was the most genuine. From start to finish the process from A-Z was easy and seamless for me. Working in the back office was Michelle his wife/partner and she was equally awesome! You cannot go wrong going with Contemporary Air System you will be very pleased I promise you that. Rick/Michelle, thanks for a great experience and I wish your company continued success! Tyread more

Contemporary Air Systems was able to quickly come out and assess my A/C issue. They were punctual and professional the entire time, as well as friendly. After the initial repair did not last, they made getting my system replaced a priority. I felt that I was being helped by a company that cared about my needs and situation, and worked with me to resolve the problem quickly and without unnecessary costs. I highly recommend Contemporary Air Systems if you have any heating or cooling needs in the Baltimore area.read more

I highly recommend Contemporary Air Systems. After dealing with the "other guys" a friend recommended Rick to me last summer to help deal with my very aged AC and furnace issues. He and his wife Michelle were always available to answer my calls and questions regarding my options for repair, purchase of a new unit, and my payment options. From the quick same day service for repair, to the expedited scheduling for the replacement, to the expert installation everything went smoothly and efficiently. They were courteous of my home and took care to keep everything protected while they worked and cleaned up afterwards. Michelle checked in on my frequently throughout the whole process. I will never go anywhere else for my HVAC needs. Thank you Rick, Michelle and Justin of Contemporary Air!read more

I had a wonderful experience with Contemporary Air Systems! Michelle and Rick contacted me very quickly after I inquired about their services and they came out at a time that works with my schedule. Rick provided the estimate on-site and it was very reasonable. After agreeing to the work, within a couple weeks, Rick installed a brand new air handler and heat pump within one day. Once Rick arrived, he made sure to keep the work area covered up. His work is careful and efficient. I couldn't have asked for a better experience with this type of work. I asked many questions about continued care of the air handler, air conditioning care, and air filters. Rick gave several recommendations and suggestions to extend the life of my unit. Michelle sent the registration the same day, which I completed that same day! They are an excellent team and I would definitely recommend this company to anyone. I am very happy with the service and grateful to interact with such great and honest people.read more

I initially called horizon But they wanted to replace my whole air conditioning and heating and they wanted over 13 k My son-in-law gave me Contemporaries number so I called and the lady was very very nice on the phone and had her husband come out the very next day. He found a scorched wire on my system, that was the problem. Yes my system is 16 years old but it's giveing me cool air and working like a charm. I know I need a new one soon but for just about half of what horizon wanted I will go with contemporary when it's a little cooler out so they don't die in my craw space. Lol. Thank to all from contemporary heating and air.read more

Our air conditioning system was installed 2 or 3 years ago and I have never written a review before for anything but this company is an exception. They were reasonable, professional, honest with their answers, spotless with their work, Michelle was so pleasant and helpful with the warranty and billing and I could go on and on but you get the picture. I've recommended them confidently several times. I came across their business card the other day and just had to write this review. Oh, and our 3rd floor in our townhome is actually "cool".read more

Stop looking! You've found your Baltimore-area HVAC company! By far the best home service company we've ever had take care of something in our home. I wish they did more than HVAC! Every person we've interacted with at Contemporary Air Systems has been responsive, honest, reliable and customer-oriented. They've been maintaining and repairing our home's two crummy (installed by previous owners) HVAC units for four years now, including next-day attention to "help! the house is way too hot!" mid-July AC breakdowns two summers in a row (two different problems, each efficiently managed by Rick & his team). Thank you for all you do!read more

Contemporary Air replaced my (ancient) furnace and central air units. My furnace stopped working abruptly on Christmas morning. I called Contemporary - at noon on Christmas day. The owner called me back - within the hour! Service men came to my home at 7AM on the 26th and on the morning of the 27th the new units were installed and functioning. After the workers left the owner called to ask about their work - and then came to my house to inspect that evening. I could not ask for better service. Professional - and fair.read more

I will begin this post by noting that I did not purchase a system from Contemporary Air only because they did not sell the make and model I ultimately wanted. I dont submit many reviews but I felt it was necessary to credit Michelle and Rick on their honesty when helping me narrow my choices. They made it crystal clear that the expensive systems other dealers were pushing were unnecessary and I should keep it simple. When you are in the market for HVAC services, I would certainly reach out to the professionals at Contemporary Air Systems.read more

From the first time I called Contemporary Air until the final install was complete the service was outstanding. Michelle handled all the scheduling and was even able to move our appointment once our current HVAC system started really acting up. I was happy about that! Rick and his crew showed up on time and were very professional and helpful in explaining the system they would be installing (Bryant 3 ton heat pump system). My husband and I were both surprised that it only took one day to complete. The job is very neat and tidy and by that I mean all wires are taped and not hanging, PVC pipe is secure and not flapping around, all debris was cleaned up. We are very happy with the installation, price, product and customer service. My husband and I both would highly recommend Contemporary Air!!!read more

Wow! Fast, friendly, knowledgeable, considerate. Day before Thanksgiving and my family woke up to 56 degrees! Was able to get an appointment at a reasonable cost in just a couple of hours. But, Michelle asked a few more questions and walked me through some preliminary diagnostics, saving me time, money, and cold toes! She called me back just when she said she would (2×) to be sure everything was up and running. The next time something goes wrong, and it will, this will be the family I trust to keep my family warm.read more

The number #1 reason we picked Contemporary Air is we felt we could trust them completely and they did not disappoint! Thanks again Ellieread more

Contemporary air systems replaced my 49 year-old heating and air conditioning system. The work was efficient Timely and very very satisfying. Their technicians are courteous and very considerate of your home. The only complaint I had was Ithe replacement was unreadable for me. The installation was on Friday and a replacement thermostat was delivered promptly on Monday morning. I am thoroughly happy with every aspect of their work and highly recommend them.read more

Contemporary Air Systems has been great since I called nervous about a noise my old unit was making. Rick came out to check and upon discussion, we decided to start moving toward a new system. He & Michelle made the process easy. He worked with my schedule, which is difficult at best, and she worked almost exclusively through email, because it's easier for me. The actual installation was quick & didn't really disrupt the household. Both technicians were awesome, and Rick came to double check everything just in case. The new units have both been tested in this crazy MD weather and they work equally well. I'm excited to see how they impact our power use. I'm very happy with CAS and the treatment from their staff. I'd recommend them to everyone who needs the services they can provide.read more
