When Do You Need to Change The Coolant in Your HVAC?

Is your air conditioner failing to cool your home?

Does it take forever to see a change in temperature after you set your thermostat?

Do you think your system is working harder than it should to cool down your home?

These problems may be the direct result of being low on Freon or Puron. At CMR Mechanical, we always recommend a seasonal clean and check on your system to ensure that it’s running smoothly and efficiently to avoid potential problems later in the heat of summer.

Making sure that your system is serviced each year will help keep your unit operating at manufacturer standards. This will affect both the energy efficiency and longevity of your system, saving you money over time. Imagine how comfortable your house will be all year round by making sure your system is properly maintained!

If your air conditioning unit is older, it uses Freon. If your air conditioner is newer, it probably uses Puron as a refrigerant. Puron was approved by the Environmental Protection Agency to help phase out Freon. It’s the first long term solution to Freon’s harmful effects to the environment! Unfortunately, you can't just replace Freon with Puron if you want to be eco-friendly. You have to purchase a whole new air conditioning unit to make the environmentally friendly switch.

How Often Does the Air Conditioner in Your Ann Arbor Home Need Service?


Once a year! According to Angie’s List, “it’s a good idea to have it inspected, serviced and cleaned once a year — ideally in the spring — to ensure it operates at peak energy efficiency and is ready to cool your house during the months you need it most.

As your HVAC system runs, it accumulates dust and dirt in key areas that affect its efficiency, like the condensing coils and air filters. Left unchecked, your A/C system can lose 5 percent of its operating efficiency each year because of this buildup, meaning it can’t cool your house as capably as it could if it were clean.”

Your HVAC will start to work harder and eventually wear out. You’ll have to spend a lot more money on service calls and repairs if you wait till the air conditioner in your Ann Arbor home fails. 


Contact us at info@cmrmechanical.com or call (734) 424-9555. We pride ourselves on honest, quality service, and we’d love to help keep your home warm in the winter, cool in the summer, and comfortable all year long!

Could Your Air Conditioner Problems Be Compressor Related?

Has your air conditioner been giving you problems?

Are you spending a lot of money on expensive fixes, only to have the problem come back time after time?

The air conditioner in your Ann Arbor home could stop working for many reasons. However, if the problem is with the compressor, those problems can be prevented!

What is an Air Conditioner Compressor?


The compressor for your air conditioner is sometimes called “the heart of the unit”. It’s one of the key components, your air conditioning system won’t function without one. If your compressor fails, it can be costly to replace.

The compressor’s job is to compress refrigerant air through the system and remove heat and humidity from the air.

Problems with AC Compressors Can Be Prevented!


The most common problems with air compressors are:

  1. Dirty coils – Dust and grime build up on the condenser coil, and that causes the air conditioner to be unable to expel enough heat from the system. When your air conditioner runs constantly, the increased pressure can cause the compressor to overheat.
  2. Too much refrigerant – If you accidentally add too much refrigerant, or the wrong type of refrigerant, you can kill your compressor.
  3. Blocked suction lines – If your unit isn’t cooling as effectively as it used to, it could be due to blocked or damaged suction lines. This can also lead to your compressor overheating and failing.
  4. Electrical problems – An electrical failure can cause a buildup of acids that damage other parts in addition to the compressor. 
  5. Inadequate oil lubricant – If there’s not enough lubricant running through the system, your compressor can’t work properly. To ensure you have the right type and enough lubricant, you should have your unit regularly maintained by a professional.

Energy Tips to Help You Save Money on Air Conditioning Your Ann Arbor Home!

Are you frustrated when you get your air conditioning bill?

Do you pull your hair out when you see how much it costs?

Do you feel like you’re throwing money out the window? 

Are you at a loss about how to save on your bill without lowering or turning off your AC completely? 

You’re not the only one! Many people feel like their energy bill is too high, but aren’t sure how to fix it. At CMR Mechanical, we can not only help fix the air conditioning in your Ann Arbor home, but we’ll take care of the maintenance afterwards, too. A big part of being happy with your AC is being happy with your monthly energy bill. We can help educate you on how to keep your bill down without keeping the AC off. 

And with our 24-hour service line, you never have to feel left out in the cold (or the heat)! We want you to be as knowledgeable as we are when it comes to your furnace and AC unit. Check out these 5 tips on how to keep your AC bill down! 

    air conditioning Ann Arbor
  1. Try buying a new programmable thermostat. When you’re away from home, set the thermostat lower and program it to be higher for when you return. The smaller the temperature difference between the outside and inside, the more you’ll save. 
  2. Keep objects that omit heat away from your thermostat. Lamps or household appliances can trick your thermostat into thinking it’s hotter than it really is. This will cause your AC to run longer and potentially waste your money. 
  3. Schedule regular maintenance checks for your unit. Maintenance allows you to catch issues quickly. Catching an issue early can result in less of your hard-earned money spent. Vacuum and change out filters often to keep dust and debris to a minimum. 
  4. Invest in mesh window screens. These screen intercept, up to 70% of the sun’s energy. This keeps your house cooler and your AC unit working less. Screens are especially efficient on the east and west facing windows. 
  5. When you’re away from your home or out of a room, keep shades down and curtains closed to block out the heat from the sun’s rays. 
  6. Keep your fans running on your home’s upper levels. Fans on medium to low speed will keep airflow consistent, allowing warm air escape your home faster.

Get to Know the Parts of Your Air Conditioner

Love the cool, fresh air your AC provides, but have no clue how it works? Interested in an intimate look at your air conditioning unit? Want to impress with your knowledge of AC pieces and parts?
heating and cooling services Ann Arbor


Naming all the parts of your air conditioning unit probably isn’t a great conversation starter, but as a homeowner, getting to know this important piece of equipment is to your benefit. If a problem with your HVAC ever pops up, you’ll be better equipped to handle it. Or, if you’re ever in the market for a new unit, knowing something about air conditioners will make you a smarter consumer.

Without further ado, meet five basic components of your AC unit!

  • Evaporator: a series of coils which convert refrigerant liquid to gas, creating a cooling effect. A fan blows across the cold coils to bring cool air into the house.
  • Expansion Valve: de-pressurizes liquid refrigerant, allowing the evaporator to do its job. 
  • Condenser: condenses refrigerant vapor into a liquid which is used by the evaporator. 
  • Compressor: pressurizes refrigerant so the condenser can work its magic, turning gas to liquid.
  • Lineset: the copper highway which transports refrigerant between the other components.

With a few simple definitions, you now understand the basics of how an AC unit works. Now put that knowledge to work!


Still want to know more about your air conditioner? Give us a call! We’re happy to answer questions or provide heating and cooling services in Ann Arbor. CMR Mechanical prides itself on honest, quality service and we are ready to help you today!
