Frequently Asked Questions

How often should I have my A/C unit inspected?

The standard industry

Response to this question is to have two inspections annually - one for heating and one for cooling.  We advise our customers to have an inspection as often as they feel necessary.  What we often hear is a concern about refrigerant (Freon) levels. 

It is important to know that refrigerant will remain in the system forever without any change unless the system develops a leak or if it was installed improperly.  Another important consideration is that seasonal inspections are meant to find immediate or identify potential future problems but does not guarantee that your unit will run problem free.

What is the best time to have my A/C unit inspected?

The best time

To have an inspection is when conditions are as close as they can be to the season you are in.  For example, if you are having a cooling inspection it doesn't make much sense to have your unit inspected when it’s 80 degrees.  This is similar to checking your snow blower in the middle of summer.  Sure it runs, but will it perform as it should when it needs to? 

This is why we recommend scheduling an inspection when temperatures reach the 90’s.  These conditions give us truer readings and a better idea of how your unit will run in the middle of the season when you need it most.  

How often should I change my air filter?

The standard industry

Answer is once a month.  We believe however that you should change your filter dependant on your particular situation.  For example, those houses with very little carpet or those with pets will probably find that they need to change their filter more often. 

Little things such as the type of food you prepare or the type of filter you have can impact how often it needs to be changed.

What type of air filter should I choose?

We always recommend

We always recommend a disposable pleated air filter to our customers. If you use a filter that is not good enough you may not be filtering the air enough to catch the fine dust and particles that may plug your coil causing system damage or an expensive repair. A sure sign that your filter is inadequate is if there are signs of dirt or dust at the supply vents. A filter that is designed to catch small particulates is usually very dense by themselves causing an airflow restriction when they are perfectly clean. Also, in the case of washable filters are very difficult to tell when they are dirty, therefore don’t get cleaned as often as they should be. 

A simple, inexpensive, disposable, pleated filter is the best thing you can do as a homeowner to maintain you equipment. When it comes to air filters there is such a thing as too much of a good thing.

What type of thermostat should I have?


Thermostats are recommended since they are the most accurate.

When should I consider replacing my equipment?

The advice we

Give to our customers is that they begin to plan replacing any piece of equipment that is around 8 years old. This is not to say that the equipment should not be repaired only that that this is the time frame where replacement should be considered.

Do I have to call the company that installed my equipment

if I have a warranty issue or because their ad says they service my equipment brand?

Most contractors should be able to honor any manufacturer's warranty, as long as the problem is an equipment problem and not due to improper installation. Any contractor should be able to make this determination.

What should I check before I call for service?

One of the first things

You can check before calling for service is your thermostat. Ensure it is set to the proper function and temperature. Also, check that the battery icon is not showing. It would surprise most just how often service calls are placed for that reason alone. The next thing to check is the breaker panel. For those customers with split systems (condensing unit outside & air handler inside) there are two breakers to check.
