Whether it’s the dead of winter or the dog days of summer, as a responsible homeowner, you need to keep the health of your AC in mind. Like all HVAC systems, your air conditioning requires an annual inspection (and, most likely, a tune-up) to keep it in excellent condition and to comply with the terms of the air conditioning system’s warranty, if applicable. A quick tune-up can save you a lot of trouble, time and money in the long-run.

Regular Maintenance is Key

Even if your AC seems fine, you should still have it inspected by a licensed HVAC technician annually. A licensed technician will conduct a thorough inspection to make sure your AC is in tip-top shape. From checking the motor and the fan blades to the coolant, compressor and the wiring, the technician will go through a detailed checklist to ensure nothing is awry. If any problems are flagged, you have the confidence of knowing that they will be repaired right away, and repaired correctly the first time.

Tell-Tale Signs of Trouble

Unsure if your AC needs help? Here are a few common indicators that point toward a malfunctioning AC:

  • Poor air circulation
  • The AC does not respond to the thermostat when adjusted
  • Loud noise when in operation
  • Excessively high energy costs
  • Water leaks from the back of the unit

The Benefits of a Tune-Up

What are the benefits of having a professional HVAC technician conduct a tune-up? Here are some, to name a few:

  • Better air quality – the vents and various component parts are thoroughly cleaned
  • The filter will probably be replaced, thus eliminating pet hair, dust, dirt and other allergens
  • The AC will operate more efficiently, thus reducing your energy bills
  • You lower the risk of having an AC emergency when the temperature rises

Don’t Wait for an Emergency

In the winter, you don’t want to wait until your furnace fails and you have no heat to call for emergency repairs. Likewise, in the summer, you don’t want to wait until it’s sweltering outside and your AC fails, resulting in dangerously high temperatures within your home.

Instead of waiting for a disaster, contact us today to schedule your next tune-up.

What could be worse than your furnace turning off unexpectedly on a cold night? Your furnace tripping your circuit breaker is worse, and it’s also pretty inconvenient to have fixed. However, as your circuit breaker is meant to protect your house from dangerous electrical issues, a tripped circuit breaker is vastly preferable to the alternatives. Regardless, you need to fix the issue so you can get the heat on and don’t put your health or your home at risk.

Before troubleshooting the issue, it is important that you don’t just keep flipping the breaker back on. Flip it once, but if it trips again, it is for the best to keep it off.

Why Is The Furnace Tripping the Breaker?

There are two primary reasons your furnace is tripping the circuit breaker every time it tries to kick on. It could be an overloaded circuit in which your furnace is getting too much current. This can happen typically because your circuit breaker is not the correct size to accommodate your furnace’s electrical needs. If you have been doing renovations or recently got a new furnace, then this is likely to happen.

Another reason your furnace is tripping the breaker can be due to a short circuit. This means that something has gone wrong inside your furnace and it is causing the issue. Essentially, your circuit breaker is tripping so that it doesn’t cause any more damage or worse, a fire. If this is why if your breaker keeps tripping, keep the furnace off.

Unfortunately, if either of these issues are manifesting from your furnace, it is not something that you can really fix yourself. If it is an issue with the circuit breaker itself, an electrician will be needed. However, if it is a problem with your furnace, you will want to call a qualified HVAC repair service.

Contact us today and one of our trained HVAC experts can examine your furnace to find what is causing it specifically to trip your circuit breaker every time it switches on.

When any appliance makes loud noises, it is usually not a good sign. If your furnace is making a loud sound, it means that something is wrong. However, the tricky part is figuring out what part isn’t functioning properly. Calling in a service technician is a quick way of figuring it out, but knowing what your furnace noises likely mean can point them in the right direction.

Blower Motor

When your furnace kicks on, if you hear a loud screeching or rattling noise then it means it is probably time to lubricate the bearings on your blower motor. As the major moving part that forces warm air into your home, it needs frequent lubrication.

Blower Wheel

If you begin to hear the sound of metal scraping on metal, this is one of the most serious sounds you can hear, and it is probably your blower wheel. When metal scraps on metal, it wears everything down quickly. The fan has most likely become loose and it bouncing around in the housing. Turn off your furnace so no further damage is done.

Dirty Burners

Does your furnace make a boom when you turn it on? It’s kind of scary, and you should be concerned about it. That “boom” is essentially the gas building up and then suddenly exploding. In many cases, the burners need cleaning. When the burners are soiled, they can delay the ignition and cause that terrifying noise.

Loose Screws

The vibration from the furnace has a way of loosening screws sometimes. If you hear a slight rattling noise, the most likely culprit is a loose screw somewhere that needs tightening. However, this noise shouldn’t be ignored.

If you can’t find the cause of the noise you’re hearing, it is important to call a service technician at M&M Mechanical, Inc. to track it down. It is not something to be ignored, so contact us today!

Heat pumps are electrically powered, mechanical devices used to take heat from the air. But what about when it’s cold outside? Even cold air contains a certain amount of heat, and heat pumps are very good at removing that heat.

In the winter, the heat pump extracts the heat from the cold air and transfers it to the inside of your home, keeping it warm. Conversely, in the summer, the heat pump removes that warm air from inside your home and sends the heat outdoors, replacing it with cool air inside.


  • Moving heat instead of generating it saves you money. Remember: there’s a cost to generating heat by burning fuel or gas.
  • The process is electro-mechanical, so there are no fuel bills.
  • Provides both heating and cooling at lower costs.
  • They are highly efficient efficient (if auxiliary heating strips remain off).

You will typically find heat pumps in areas of the country that have more moderate climates, because you can only remove so much heat. That being said, below are some disadvantages to heat pumps.


  • They cannot transfer enough heat in colder climates.
  • They are equipped with auxiliary heating strips to augment when outside temperatures are low. When the auxiliary heat strips are energized, they consume huge amounts of electricity.

It’s important to mention that as technology advances, heat pumps are being seen in less temperate climates. Some homeowners will pair heat pumps with oil or gas furnace units to offset costs.

Our discussion has primarily been about the most common type, the air to air heat pump, but there are three types of heat pumps:

  • Air to Air: These are the most common, and they draw their heat from the air as the name implies.
  • Water Source: Draws heat from an outside water source.
  • Geothermal: Extracts heat from the ground. These are becoming more popular but can be quite costly.

Overall, heat pumps can be an excellent alternative to furnaces and air conditioners. Our team at M&M Mechanical, Inc. will be able to answers to any questions you might have, so contact us today for more information.

For many homeowners, regular HVAC maintenance serves one purpose, primarily: to prevent your furnace from breaking down on the coldest night of the year right when you need it the most. However, for some, that’s not a good enough reason to spend the money on maintenance. What most homeowners don’t know is that regular maintenance on your HVAC will actually save you quite a bit of money in terms of energy costs.

Regular furnace maintenance that is carried out by the service technician includes:

  • Checking and sealing vent connections
  • Combustion-efficiency testing
  • Checking the physical integrity of the combustion chamber and the heat exchanger
  • Adjusting blower control and removing dirt
  • Checking the fuel input
  • Cleaning away and rectifying the causes of dirt, soot, and corrosion

Many of the tasks listed above work to keep your furnace working properly, but they also go a long way towards energy efficiency. Tasks like sealing vent connections and combustion-efficiency testing will go a long way towards keeping your energy bills lower.

Furthermore, while you can do it yourself, seasonal HVAC maintenance is a great way to remember to change your air filter or at least make sure it gets done. If there is one simple way to lower your energy costs this winter, it is to change that air filter out every three months or when you notice that it is dirty.

Regular HVAC maintenance is great for identifying potential problems and getting them fixed before they become actual problems. However, it really does make a meaningful impact on energy efficiency. All furnaces are designed in such a way to work as efficiently as possible, but if there is a problem—even just a small crack somewhere—it can damage the integrity and it will cause it not to function as it needs to heat your home efficiently.
