Ready or not, the sweltering heat of summer is here. A more important question, however, is whether your air conditioner is going to get you through the season.

Too many people take their air conditioners for granted. If it works, it is ignored, and it only gets the attention and service it needs when it breaks and needs costly repairs.

Unfortunately, this attitude is penny-wise but dollar-foolish. Low cost regular maintenance, in the form of an annual air conditioner inspection and tune-up, can guarantee that your home or business is comfortable on the hottest days of the summer. It can also help you avoid the dreaded air conditioner failure, which inevitably seems to happen on the hottest day of the year when air conditioning repair is at a premium.

The assumption that just because your air conditioner worked fine last year, it does not need a tune-up this year can be a costly mistake. Air conditioners, like all machines, need regular inspection, maintenance, and tune-ups to make sure they work at their peak efficiency and do not fail when they are needed most.

While your air conditioner was sitting idle before you turned it on as the heat started settling in, dirt, dust and debris were slowing building up on the evaporation coils in the unit. This acts as an insulator, which impacts both the cooling and electrical efficiency of your air conditioner, can severely decrease the lifespan of the unit and increase the likelihood of an expensive failure.

It is also fairly common for air conditioners to lose coolant during the cooler months leading up to summer. A slow coolant leak can rob your air conditioner of its cooling power, causing it to work harder, and use more electricity, while cooling less. Inefficient cooling can cause big money on your electrical bill.

Electrical problems can also develop during the off season, which can cause expensive failure of your air conditioner when you need it most.

A full season inspection and tune-up now by a qualified air conditioning professional can fix these problems now, and ensure that the rest of your summer will be a cool one. The cost of a tune-up is more than outweighed by the simple peace of mind today – and can help you avoid the possibility that your air conditioner will die at the height of summer, when you need it the most. It is a small investment today that can save you hundreds of dollars and days of discomfort later.

With the official start of summer upon us, now is the time to make sure your unit is working its best. This is where an air conditioning tune-up enters the picture. Having an air conditioning tune-up is a great way to make sure your home stays comfortable during the summer months. Along with this, here are three other reasons you may want to consider having a tune-up.


Longevity of Your Unit

Believe it or not, tuning up your air conditioning unit is a great way to make sure your unit lasts for many years. When malfunctions are caught early on, you can correct them quickly, which can improve the longevity of your system.


Cost Savings

Along with keeping you comfortable in your own home, it is possible that a tune-up can actually lower the amount of money you spend on your electric bill every month. A tune-up is a great way to make sure your system is working at its fullest capacity, which can help reduce the amount of energy that it needs to use.


Make Upgrades

Finally, having an annual tune-up could also mean that you are able to perform a few maintenance items on your system. This could be something as simple as installing a programmable thermostat or replacing items in your unit that may not work as efficiently as before.

These are just some of the reasons you should consider having an air conditioning tune-up this season. Following this advice will allow you to know that your unit will be able to stand the hot summer months and still be functioning properly at the end of the season.

It’s frustrating enough to fight the traffic every day to come home after a day on the job, only to find that your air conditioner has stopped working. A hot, toasty home wasn’t exactly what you had in mind for a relaxing night, especially when the outdoor thermometer is shooting beyond the 90˚ mark. So, just what causes your air conditioning unit to flat-out stop working? Here are 4 reasons your A/C stops working.

1. Filters need to be cleaned

This is one of the simplest situations to take care of, but one that people often forget to do. If your filters are not maintained – that is, cleaned and/or changed regularly – the air cannot flow unrestricted through the vents. Dirt, dust, and mold collect on the filter, inhibiting the effectiveness of your unit.

2. Leaky refrigerant

The air conditioning unit in your home needs refrigerant just like cars do – it’s just a different type. Refrigerant is a necessary gas in the cooling process; without it, the house won’t get cool. Sometimes, the refrigerant levels dip too low. There are two reasons for this happening: 1) the unit was not filled properly during installation, or 2) you have a leak. Refrigerant, when simply added to the unit, will likely solve the problem only temporarily. If the source of the leak isn’t discovered and fixed, it will only be a matter of time before the leak starts up again. For this reason, consult a professional, like the ones here at M&M Mechanical, to get to the root of the problem.

3. Breaker is tripped

Sometimes the air conditioner can trip your breaker and the whole thing will shut down. If you discover that, after flipping the breaker back on, it trips again, it’s definitely time to call your technician for an assessment.

4. System is frozen up

Anytime you see ice on the evaporator coil within your home, it is bound to get warm inside. The evaporator sends the hot air out to the condenser outside, but when the evaporator coil is frozen, it can’t do the job.

These are some of the common problem areas of air conditioners. If you are experiencing any air conditioning issues, give us a call at (703) 751-1011 to help you resolve your issue.

Whether your home improvement skills are limited to hanging the occasional shelf or you consider yourself a budding Bob Vila, there is one home improvement project that should always be left to professionals – air conditioning installation.

A professionally installed air conditioning system is generally a one-time, painless operation. Aside from annual inspections and tune-ups, a professionally installed system will give you many, many years of efficient, trouble-free installation.

Non-professional installation, however, can cause you to have a system that’s inefficient and prone to frequent breakage. In extreme causes, it can be a safety hazard, damage your home or belongings, and negatively impact the value of your home.

A professional installer has many tools at their disposal to make sure you get the best system and the best installation for your home.

A professional installer will carefully evaluate your home to make sure you have the right size air condition system. Choosing the right size system is the first step, and there is a delicate balancing act of that takes into account many variables – too small an air conditioning system, and the system will be inefficient, will struggle to cool your home, will use more electricity, and will be more prone to needing costly repairs; too large a system will cause larger up-front cost and higher electrical bills in the long term.

The installer will also have the knowledge and experience necessary to determine proper air-flow for maximum efficiency. They will be able to design and install ductwork that guarantees the most efficient air flow pattern. Improperly installed ductwork can leak or have obstructions that prevent air from the air condition system from being efficiency moved around in your home, causing your air conditioner to work harder. This can cause both inadequate cooling – and high electrical bills – as well as a shortened life-span for your air conditioning system.

Prolonged usage of an improperly installed air condition system can cost you big in wasted electricity and premature wear-and-tear on the system, which can lead to costly failures and repairs.

Having an experienced air conditioning professional, like the ones here at M&M Mechanical install your home air conditioning system can save you considerable aggravation today and both money and peace of mind later. Call us today or visit our website to schedule your free consultation.
