Why is my air conditioner blowing hot air

My Air Conditioner is Blowing hot air… what’s going on?

Another typical call at Sharp Air Conditioning & Heating is someone calling in to say their air conditioner is blowing hot air. It is even worse. We also offer services of AC repair in Gilbert.

Then if it was not blowing any air at all, especially when it’s hot enough outside without a heater blowing inside too! Below are a few common reasons for this “hot problem” and what you might be able to do to fix it.

Refrigerant Issues

Your unit’s refrigerant levels may be low if your air conditioner spews warm air. Unfortunately, this often means that your system has a refrigerant leak! If that’s the case, your air conditioner will keep running and blast heated air to match the thermostat setting.

Sometimes your system can develop a leak in the refrigerant lines and cause a prolonged leak that can reduce the amount of refrigerant in your system. Your AC system needs to have a proper “charge,” or amount, of refrigerant to operate correctly.

A few telltale signs of a refrigerant leak could be ice forming anywhere on your system, or you might even see an oily substance on your outside unit. If you see any of these signs, give Sharp Air Conditioning & Heating a call for heating and cooling Mesa AZ, and we will send a professional out. It is usually an inexpensive repair if your system is low on refrigerant.

A Clogged Air Filter

We will keep saying it repeatedly, but clogged air filters are the number one culprits for many HVAC issues. While a dirty filter might not be the sole reason your air conditioner is blowing hot, it can significantly restrict airflow.
Changing your filters can be one of the most uncomplicated maintenance issues you perform on your home; it’s all about remembering to do so. Changing dirty filters should be at the top of your maintenance list with the dust storms we get in Phoenix and the surrounding Arizona desert. Change those filters! Call us for an air filter change service.

Check Thermostat Settings

Every now and then, we get a call that we fix over the phone. Usually, the root of the problem is someone has unknowingly changed the settings on their thermostat. It can be as simple as forgetting to change over to “cool” in the spring, or the system may just have the fan on. Checking your thermostat settings before calling in an AC issue can save you time and hassle.

Condenser/Outdoor Unit

Another common issue that we get called out on is that it seems the inside fan is blowing, but the outdoor unit, also known as a condenser, does not seem to be on. The first thing to do, as a homeowner, is to check to see that the unit has power or that a breaker has not been tripped. Simply making sure the breaker is in the “ON” position can fix your issues.

Another easy fix to look for is to clear debris from your condenser. If you can see dirt and leaves and other “stuff” stuck to the sides, this will restrict your system, and it will have a hard time cooling. Again, with the Haboobs that we get here in Phoenix, Mesa, and the entire valley, dirt can build up very quickly, so a quick check can save you discomfort when you need the AC the most.

Should I Buy a Programmable Thermostat?

Sharp Air Conditioning & Heating, LLCMost new homes and many older homes now have programmable thermostats installed for the HVAC system. If your home still has an older system thermostat or one that does not have a programmable feature, you are missing out on added convenience, energy savings and other benefits of setting a schedule for your HVAC system to run.

Many people have a schedule that they follow everyday. We work at certain times, or can count on being out of the house at certain times. Also, when the sun goes down we may not want the house to be as cool as during the day. Without a programmable thermostat, this means remembering to change the thermostat every time there is a change. If forgotten, you run the risk of cooling an empty house, putting unneeded wear and tear on your system, as well as wasting precious energy when it is not needed. A simple switch to a programmable thermostat can help alleviate these problems and better help manage your energy costs.

Recently, there have been some very high tech introductions to the programmable thermostat realm, most notably the Nest thermostat or Lyric thermostat by Honeywell. While these are great options, they come with a high price tag. Sometimes that price tag is a little too much for a homeowner to take at one time. Not to worry! There are many affordable options for programmable thermostats that will give you the basic functionality of being able to set your HVAC system on a schedule, unlocking your energy savings potential.

Should I replace or repair my heating and air conditioning system?

This is one of those questions that we get asked all the time. Should I repair my older unit, or is it time to invest in a replacement? Well, unfortunately, there’s not an easy answer. You might think that we would suggest you replace your unit because we are an HVAC contractor, and we offer service for heating and cooling Mesa AZ. It’s not necessarily the case, though. Often it makes sense to repair your existing unit rather than go through the expense of a replacement. Here are some guidelines that may help you with your decision:

The first step in the decision-making process is to determine if you have a repairable or a replacement system. If you can live with your current system, keep it repaired and save money. You also don’t want to replace an old system that still works with a new one that may not work as well or maybe more expensive to operate and maintain. Sharp Air Conditioning & Heating, LLC offer replacement and AC repair Gilbert.

  1. If your existing unit was manufactured more than 15-20 years ago, it might be time to consider an upgrade, even if it’s working currently. The advancements in technology make a new unit considerably more efficient. Your savings in utility bills will go a long way towards paying for the latest team. Plus, the sad reality is that your older unit will eventually fail. There is an expected lifespan on these, and you’re getting very close to it.
  2. If you’re looking at replacing a compressor in your AC unit, that’s a substantial repair. You can think of it as replacing the engine in your car. If you love your car, you might want to replace the engine, but it will be costly and rarely as reliable as a new car. A new unit will be more reliable than replacing the compressor, and once again, the efficiency in design is something you should consider.

Those two situations are typically going to result in a recommendation to replace. However, there are times when the decision isn’t so easy to make. For example, when do you require air conditioning Chandler AZ? For the best HVAC solution, contact Sharp Air Conditioning & Heating.

One rule of thumb to consider is the cost of your repair and the age of your unit. Replacement should be a consideration if your team is beyond ¾ of its life expectance, and rehabilitation will cost more than 1/3 of a replacement. For example, if your unit is 16 years old and the repair costs $700-800, you might consider a replacement. Always keep in mind that this might be the chance to reduce your monthly utility bills with a more efficient unit.

The best option is to have one of our certified technicians visit your home or business and assess the situation. Some 20+-year-old units work fine because they’ve been maintained well. On the other hand, some 10-year-old teams need to be replaced due to neglect. A professional knows what to look for when evaluating your equipment. Of course, each situation is different, but Sharp Air can help you with your difficult decision.

Why does my AC keep running?

During the hot Phoenix Arizona summers, most people are used to their AC running quite a bit, just to keep up with the 110+ temperatures that we experience here. While it is normal for your AC to be on more than usual when the temperature goes up outside, it shouldn’t be constantly running. Here are a few troubleshooting tips to try before giving Sharp Air Conditioning & Heating a call that can save you some time and money.

  1. Sharp Air Conditioning & Heating, LLCCheck your thermostat – One of the most avoidable issues is to check your thermostat settings. With the more basic thermostats, it can be as simple as forgetting to switch your system from “ON” to “AUTOMATIC”. Having it in the “ON” position will tell your AC system to continue running, even when it satisfies the temperature you have set on your thermostat. With the more complex thermostat options that are on the market now, yours may need a little bit more programming to be set correctly. Check with your owners’ manual, or give us a call and we can try to walk you through some troubleshooting on your thermostat.
  2. Change your filters! – Airflow restrictions caused by dirty filters can greatly affect your AC system’s performance. If your AC system does not get enough airflow, it can not blow out cold air and will continue to run since it is not able to satisfy the thermostat setting. Change those filters!
  3. Dirty coils – Check to make sure there is no debris built up on your condenser outside. This is the same as a restriction for your indoor components. Restrictions can cause the system to not cooling correctly, therefore not being able to satisfy the thermostat settings leading to a constantly running AC system.

If you go through the above steps and nothing seems to work, give Sharp Air Conditioning & Heating a call and we can send a certified technician out to assess what may be wrong. Another cause of a constantly running system can be age. Your AC system may just be worn out from years of use. If this is the case, we can work with you to best determine the next steps to take in replacement.

Choosing the right size Air Conditioning System

Sharp Air Conditioning & Heating, LLCThe time has come for you to upgrade, replace or just generally install a new air conditioning Chandler AZ. Great! Get ready for lower electricity bills in your future with a more efficient unit! A question that we regularly get pertaining to installing a new system is “what size system should I get?” This is a very important question. If your new system is too small for your home, the system will continually run to keep up; resulting in high electric bills and may not be even able to cool your home at all. On the flip side, if you get a unit that is too large it will cool your home too quickly. AC systems are designed to run for periods of time, not in short bursts. Your AC system can short cycle and cause damage if it is too big for the home.

A few different factors can go into making this important decision. What is the square footage of your house? When was your house built? Do you own a single-story or two-story home? How well is your home insulated? These are all important questions to have answered. At Sharp Air Conditioning & Heating, we can come out to your home and provide a free estimate for the right system for you. If you are thinking about replacing or AC repair Mesa, give us a call today.
