Spring is in the air and those hot humid days of summer are not too far behind. This means it’s time to pay some attention to your air conditioning unit. Homeowners who neglect to schedule a regular air conditioning tune-up are often those whose units unexpectedly break down during some of the most uncomfortable times of the year.

For the small expense of a professional tune-up, breakdowns can be avoided; your unit will have a longer lifespan, and operate safely and more efficiently, thus saving you money on energy costs.

A Thorough Tune-Up Includes the Following:

  • Install gauges and check operation pressures.
  • Check voltage and amperage to all motors with meter.
  • Check air temperature drop across evaporator.
  • Check for adequate refrigerant charge.
  • Check filters.
  • Check safety switches.
  • Turn exposed dampers to cooling position, if marked.
  • Check starting contactor contacts.
  • Check all wiring and connections.
  • Check thermostat calibration.
  • Check air temperature across condenser.
  • Check that condensate drain is open.
  • Check total performance and operating efficiency of cooling system.

These are just the main checks that will be carried out by a reliable HVAC technician, like the ones here at M&M Mechanical, Inc. While you can and should regularly change the air filter yourself, you need a trained technician to give your unit a through work over to protect it and the quality of your indoor air – and save you money.

Does your furnace keep blowing its fuse? If so, it’s time for some maintenance and possibly some furnace repair. The main reasons you are having likely this problem are as follows:

1. Grime

If your furnace hasn’t been regularly cleaned and maintained, it will have been steadily accumulating dust, debris, and dead insects. Over time, dirt building up in the air filter can transfer itself to the blower motor, resulting in the motor overheating and blowing the fuse. The fuse itself can become so coated with grime that the connection will break. All of this is preventable with regular service of your furnace.

2. Loose Wiring

Vibrations from a working furnace can loosen an internal wire and result in a short. Finding, tightening, or replacing loose wires is not a do-it-yourself job. Prevention is the best policy – have your system inspected and tuned up on a regular basis.

3. Old or Faulty Parts

These may include the following:
Blower Motor – When a blower motor is failing, it tends to draw too much power which may result in a short.
Starting Capacitor – A failing capacitor can result in intermittent electrical problems.
Transformer – The transformer, which runs the ignition, timers, and controls, is necessary to convert the system to run on the correct voltage. If it is worn and not working properly, it can cause a short.
Valves – When a valve in a gas furnace is unable to open and close efficiently, it can overheat, causing an electrical short and a blown fuse.

Don’t give yourself a headache by trying to fix furnace problems yourself. You can save yourself from blowing your own fuse by arranging for regular maintenance of your furnace. Give us a call to get on a regular schedule!

Living somewhere where the temperature dips down below zero can be difficult, especially if you are used to living in a warmer climate. While you may not have much experience relying on the heater due to the warmer weather where you once lived, you need to get familiar with what kinds of steps to take to ensure your comfort and safety.

Make Visits with a Heating Contractor a Habit

One of the biggest mistakes people make regarding their heater is only contacting a professional heating contractor when there’s a problem. Basic maintenance should always be done by a heating contractor in order for it to be done right, but it’s important to also remember how important basic maintenance is.

By contacting the heating contractor and having them visit your home, you can get instructions on how to properly use it and have any pressing questions answered so that you can use it the way it should be.

When it comes to heating your home, one of the most important things is that you have a well-functioning heater or furnace. To help make sure this is the case, it is suggested that you service your heater regularly. Here is some information to help you determine when the best time to service your heater is.


The best practice to undergo, when it comes to servicing your heater, is to do so on an annual basis. A technician should come to your home and review your entire system. In the end, this will help determine if any issues are present that need to be addressed.

When the Season Changes

In some instances, it is even a good idea to take a look at your furnace or heater when the season changes. This could be a good time to make sure it is ready for being used for the winter or being turned off during the summer.

When There are Issues

If you notice your furnace is not working properly, it is definitely time to think about servicing it. Doing so can help make the entire system last longer and work more efficiently. While you are working through these issues, you should also make sure you are cleaning your furnace and keeping debris from getting inside its working parts.

Avoiding servicing your heater could lead to serious issues like carbon monoxide poisoning or even house fires. For best results, make sure yours is being serviced at least on an annual basis. This will help keep you warm and safe in your home.
