How long will my new furnace last?

The life expectancy of a furnace, per the manufacturer, is 10-15 years. Anything beyond that could lead to possible breakdown.

Why can't I use my existing furnace and add on the AC?

CMAGS always recommends furnace replacement when an existing furnace is over 10 years old with new AC installation due to efficiency capacity. A furnace and AC share a blower and should be replaced at the same time. If you match a new AC system with an old, inefficient furnace, it can potentially decrease the lifespan of the new AC. In order to get the correct amount of airflow and most of the new AC system, we always recommend replacing your furnace.

Additional note: new AC systems matched to older furnace can have issues with warranty claims.

How often should I have maintenance done on my furnace?

We recommend having maintenance done on your furnace once a year. We start performing our annual heat inspections in the fall, once the weather is below 60°F.

My pilot has turned off and now the heat won't work. Is there anything I should check before calling CMAGS?

If your thermostat runs on batteries, you can try switching them out first, and check the settings to make sure it is set to AUTO. Additionally, make sure your emergency switch did not get flipped (which is the red switch usually found in a stairwell or closet). Finally, check that the unit itself is not turned off (emergency shut off).

I wanted a larger AC unit, why did you recommend a smaller one?

Oversizing a system can cause it to short cycle (on and off) and end up causing wear and tear. It will also cause lack of humidity being removed from the area. Oversized air conditioners don't run for a long time because they satisfy the cooling load quickly and then shut off. When we quote an AC system, we quote the appropriate size based on what is needed for your home to ensure that it cools the home. It will not properly cool your home if it is oversized.

Why should I look into a mini split system for my home?

Mini split systems are an economical solution to heating and cooling for a variety of reasons. They run on electricity - saving on gas or oil. Duct work isn't necessary! So whether you don't want the cost associated with ducted systems or your home is simply not set up for ductwork, air conditioning becomes an available option.

How often should I have maintenance done on my mini split system?

We recommend having maintenance done on your mini split system once a year; because your mini split system performs both as a heat source and cooling source, you can schedule your maintenance any time within the year (but we recommend scheduling in the fall or spring for accurate testing results).

My mini split isn't working, how can I troubleshoot?

Check the remote batteries to make sure it is working, look to see if any breaker switches flipped, or try to turn the system off and resetting it. If these options do not work but there are any error codes, please try to record the codes for us, and we can have a technician stop by to perform a diagnostic report!

My water heater is leaking, what should I do?

If you think your system has a leak, don't hesitate to call! If it is found to be leaking from the top part of your water heater, that may not pose as a serious problem and can end with a quick fix; however, you may need a replacement if the leak seems to be dripping from the bottom of your system, which can be due to an internal corrosion.

How long do water heaters usually last?

Typically, it depends on the unit itself: standard water heaters have a lifespan of about 10 years, while a tankless system's lifespan is about 20 years since.

I was quoted for a 40 gallon standard water heater. Should I get a bigger water heater?

Standard 40 gallon water heaters are suitable for most homes. Having a water heater that is too big for your home's needs is wasteful, will cost you more money, and is less efficient. If a larger system is necessary, the estimator will be sure to collect any additional information needed.

How do I know when it is time for a replacement?

Signs that your system is nearing the end of its lifespan include any trace of rust in your water and water leak underneath you unit (both are a sign of the internal system corroding). Additionally, pay attention to any noises the system may make that are unfamiliar to you. Try to record sounds and take pictures of any abnormalities if possible.
