Why is my AC not working?

When the hot temps are here and your air conditioning unit quits working, you need it fixed quick. While it’s true that many repairs will require a professional HVAC tech to fix the issue, here’s some things to check for yourself before making that phone call.

Is the unit running, but not cooling?

First check your thermostat. Do the batteries need to be replaced? Is is set to cool, not just the fan? If there’s no problem there next take a look at your condenser. Is it dirty or airflow blocked? It may be a faulty compressor or refrigerant leak. These would be problems to have a HVAC technician address.

Not cooling enough?

If there just doesn’t appear to be adequate cooling, first try lowering the thermostat several degrees. If that doesn’t cool the house down you might have a dirty evaporator. Properly clean the evaporator then let it run several hours and see if that helps. If either of those suggestions do not work, you may have an undersized unit.

Also take into consideration how hot it is outside. If temps are 100+, your unit may not be able to keep your home 65 degrees. If you are unsure about whether or not you need to replace your air conditioning unit, check with your local HVAC professional.

Condenser not running?

If your condenser isn’t running at all, check to make sure it has power. Is there a blown fuse or tripped breaker?

When to call your HVAC expert?

If you’ve still got a problem after troubleshooting it’s time to call an HVAC contractor. Also if you’re not comfortable with any part of checking it yourself make that call. Make sure you have a basic understanding of the unit before trying any of these items.

How Does my Air Conditioning Work?

Did you know the first functioning Air Conditioner was created in 1908 by G.B. Wilson? Do you know how an air conditioner works?

You air conditioner moves hot air from inside to outside, which in turn cools your home. A/C’s blow cool air into your home by pulling the heat out of the air.

The air is cooled down by moving the air over an evaporator coil. Let’s compare this to when water evaporates from your skin and causes cooling. This evaporator coil is filled with a special liquid called refrigerant. The refrigerant changes from a liquid to a gas as it absorbs heat from the air.

The refrigerant is pumped outside of your home to another coil, the condenser. It’s called a condenser because the refrigerant condenses from a gas back to a liquid.

A compressor (pump) is used to move the refrigerant between the two coils and to change the pressure of the refrigerant so that it evaporates or condenses in the correct place.

When Is It Time to Upgrade Your Air Conditioner?

So your air conditioner has served you well for many years now, but it’s beginning to show possible signs of wear and require more repairs. Is it taking longer to cool your house down? Trouble maintaining temperature? These are some signs that it might be time for you to consider upgrading your HVAC system.

When you decide to upgrade your air conditioner, there are a multitude of benefits to consider. Even if your current A/C seems to runs fine, investing in a newer, energy efficient model could save you a sizable amount on utility bills.

So how do you know when it’s time for an upgrade? Here are some signs that your old air conditioner may be due for replacement:

  1. It’s more than 10 years old.
  2. There’s a noticeable difference of temperatures between rooms.
  3. Your energy bills are continually increasing.
  4. It needs repairs more than once or twice a year.
  5. The cost of repairs are more than 50% of what it would cost to replace the system.

How much does a new furnace/heater cost? 4 things you should know first

If you are looking a purchasing a new furnace I’m sure the first thing you are wondering is how much it will cost. Due to each homeowner’s needs and home details it is impossible to give a “one size fits all” answer. Here are a few important things to consider to help you get a better idea of how much you will be spending and what questions to expect.


  1. Your Energy Source

The first thing to consider if the type of energy source being used. Usually, electric furnaces are the least expensive, with gas then oil furnaces.

  1. Efficiency

Much like computers, furnaces are much more efficient than the huge mammoths from back in the day. This means you have so many different options when looking for a new furnace. A furnace with higher AFUE ratings will run more efficiently, and so they will cost more to purchase upfront, but end up saving you money in the long run on your utility expenses.

While you search for a new furnace, remember that a jump from a standard efficiency furnace to a high-efficiency furnace can cost anywhere between $500-$1,000+ depending on the size and energy source.

  1. Size Does Make a Difference

Having the right sized furnace can save significant amounts in energy costs over time. It can also save money upfront.

As with most things, bigger = more expensive. Have your HVAC contractor determine the correct sized unit for YOUR home. Over sized furnaces can cost more upfront and cause higher energy costs over time.

  1. Installation

Installation costs have several factors. Time it takes to install the equipment, where it is being installed, difficulty of installation, and may include new duct work. I know you may be thinking your ducts are good to go, but sometimes if your new equipment is more efficient new duct work may be necessary for proper air flow and reach the maximum efficiency of your new furnace.


When is comes to HVAC work, it varies greatly on your home and the equipment you pick.

It can be a challenge process to find the right furnace when you consider all the factors. When you begin your search for for the perfect fit for your home and your pocketbook, use this info as a starting point to make an informed decision.

6 cheap ways to Stay Warm

With this super chilly weather you might be tempted to crank up the thermostat. While this may be the first thing you think of and the quickest way to warm up, here are several cheap ways to stay warm.

1. Reverse your ceiling fans.

Most ceiling fans have a switch to reverse the blades. Switch the direction of the blades and the fan will push air downwards. Since warm air rises the blades will push the warm air back down towards the ground.

2. Seal the windows

Go your your local home improvement store and buy some caulk. This is another cheap and great way to keep the warm air inside.

3. Program your thermostat.

Program your thermostat for a lower temp for when you aren’t home during the day or cover up with extra blankets at night. This is another easy way to save ion your heating costs.

4. Blankets

Get a basket and fill it with your favorite blankets. It looks cozy and is a great way to stay warm while you watch movies. Try snuggling with a blanket instead of cranking up the heat!


5. DYI draft blocker.

Take a tube sock and fill with rice. Twist or sew the open end closed. Put the draft blocker at the base of your doors where cold air can slip through the cracks.

6. Go shopping…

While this might seem like a strange suggestion it can really help keep you warm. Having comfy sweaters and sweat pants on hand can help keep you from turning up the thermostat when it’s chilly.


Obviously there are lots of ways to stay warm during the winter weather. These are easy and inexpensive things to help with your heating bill.

Why is my gas furnace making noise?

If your heater makes a loud bang when it comes on there are a couple of reasons this may be happening.

Burners need to be cleaned

If your furnace only makes this noise when it comes on the furnace burners may be dirty and need cleaning. When the burners are dirty, it causes gas to accumulate before the gas ignites. The noise you are hearing is from the built up gas and is like a small explosion.  This is not something you should ignore. This could crack your furnace’s heat exchanger.

If this is the cause of your noise, have a professional HVAC technician take a look at your heater system.

Air ducts expanding & contracting

If the noise you hear is a little away from the furnace, then the problem is likely with the air ducts.  When the blower starts it is pulling air from your house and blowing it out of the supply ducts. This causes different parts of your ducts to pop in and pop out.

Minor expanding & contracting is normal, but a severe pop could be the sign of several things. Undersized ducts, closed vents, or clogged air filters. First try opening any closed vents and changing your filter to see if that corrects the noise.

If that doesn’t solve the problem, contact AC Max to take a look and assess the problem.


Is your heater blowing cold air? Top 5 reasons why

Your heater keeps you warm and cozy on a chilly winter night. The last thing you want to deal with is cold air blowing out of your vents! There are many reasons why your furnace is blowing cold air. While some can be fairly easy, others can require the help of an HVAC professional to help. Here’s some of the most common reasons:

1. You’re not waiting long enough. Just like it takes time for hot water when you turn on your sink, it’s the same concept for your furnace. It can take a few minutes before you feel warm air blowing out of your vents. This is completely normal.

2. You’ve turned your furnace switch off by mistake. Another common issue we find more often than you would think! Quite a few people like to hide Christmas gifts in the attic and accidentally turn the furnace switch off on the way out. Make sure you turn the light switch off, not the furnace switch.

3. The fan setting. Check to see if your fan setting on the thermostat is set to AUTO. If it is set to ON your fan will run continuously. When you switch to AUTO the fan will only come on when the furnace is running.

4. Pilot light is out. If you have a gas furnace, it could be your pilot light is out. Safely re-light it, following the manufacturers instructions if you feel comfortable doing so. If it doesn’t say lit, you may need to call your HVAC pro to come take a look at it.

5. A more technical issue. If your heater is still blowing cold air and you’ve gone over the common reasons listed above, it’s more than likely caused by a problem your HVAC technician can easily address.

If your heater is blowing cold air and you need help contact AC Max (832) 752-4445. We’d be glad to help you out!
