If your house is not cooling down like it used to then maybe your A/C has a refrigerant leak.
You may be running low on refrigerant due to a leak.
Refrigerant takes on the heat from your home and sends it outdoors. So without enough of it, the system can’t perform as well. An AC works like a refrigerator. In the summer the system extracts the heat from the home and sends it outside. That is how the house gets cooled down.
Signs your air conditioner needs more refrigerant.
Your ducts are blowing warm air even when your A/C is running and your thermostat is set to cool.
Water is on the floor in places it should not be.
Your home takes a long time cool down.
Ice is present on the indoor evaporator coil, the copper lines running from the furnace/coil area to the outdoor condenser.
Higher electric bills due to your air conditioner running longer to cool the home.
Refrigerant systems are supposed to be permanently sealed, so none should escape. In very few cases, systems with a leak makes a distinct hissing/gurgling sound, but otherwise everything will sound normal. If you do hear any sound around the refrigerant line, you should turn off the a/c and call for service.
The safest approach when you think there’s a leak is to call for an air conditioner service technician. A trained technician knows how to seal leaks, and can recharge the refrigerant safely.
If your home is not cooling down, then an air conditioner service call and a refrigerant recharge could solve the problem.
Servicing or installing your central air conditioner:
We are currently coming into air conditioning season. Having an efficient cooling system will provide you the proper cooling output without having to pay extra when running the a/c. You should turn on your a/c before it gets real hot to avoid having to wait to get service once it does get hot if it turns out you need service.
How do you know if you need air conditioner service?
Do not turn the a/c on if the temperature outside is below 70 degrees. You could turn it on briefly if the temperature is above 55 to see if it is working. Check to see if the air coming out of the vents is cool.
Set the thermostat to 72 if your home is currently at 75 and you are expecting for the temperature to go up into the 80’s. You may have to wait for 24 to 48 hours after starting your a/c to dry out the humidity in the home and get a true feel for how the unit is operating. If the home does not seem to be cooling down properly you are most likely in need of service.
Once the temperature outside really starts warming up you may want to cool your home down earlier in the day. For example, If you are going to run your oven and cook, because of the heat gain from the oven you may want to turn on the a/c earlier in the day. If you have the saver switch from Xcel they can start cycling your a/c power during high peak demands from 2 to 9 as needed.
Be sure to pull the shades on the windows and make sure you do not leave your door open so that the cool air does not escape.
Installing central air conditioning:
If you currently use a window air conditioning unit or a portable air conditioner to cool your home, you’re missing out on an opportunity for both comfort and efficiency. Central air conditioning systems are designed to operate with a much higher efficiency than window units.
Window units are not usually the right size for the room they’re in. That alone can cut efficiency by quite a bit. These portable a/c units are not held to the same efficiency standards as central air conditioners.
The correct sized air conditioner is important:
A new central air conditioner should be the right size for your home if you want it to cool the space efficiently. That means that it shouldn’t be too small, as it won’t be strong enough to cool the area and may run nonstop in an attempt to do so.
It also shouldn’t be too large. An air conditioner that is too large may start and stop repeatedly, which wears down the components and is not as efficient. Our technicians can make sure you get the right sized unit for your home.
Check the SEER rating:
A/C units that have a higher SEER (seasonal energy efficiency ratio) are better. These units will cost more upfront, but it’s worth it over the long term. Choose a SEER rating of 16 or higher for the best results if you are planning on staying in the home.

Your thermostat should give you a warning when the batteries are low and make sure you replace them.
A friend of ours went on vacation and when we went to check on their home a few days later it felt like an oven. It was 120 degrees inside. It turns out that with some furnaces if they are running when the batteries die then the furnace just keeps running as it does not know to turn off.
If this happened to your house it can cause all kinds of problems. The toilet is likely to leak as the wax rings that provide the seals will melt. There can be other issues and even the possibility of an explosion so make sure you change your batteries.
The typical life of a furnace filter is 3 months. This can vary based on how much the fan is running, how dirty the ducts are, and the lifestyle of the tenant/homeowners. Pet hair and dander can be a significant factor as well. The best way to gauge how often the furnace filter needs to be changed is to check it often and see how dirty it gets.
You should never let the filter get to the point when you hold it up to the light and only 50% of the light is visible looking through the filter.
A good rule of thumb if you live in Denver, CO is to replace the filter in the fall when the furnace first starts running a fair amount. Replace it again at the end of January and if you forget to check it again at least you are changing it twice a year and this should be good enough to make sure it is pretty clean. If you have a two stage high efficiency furnace the fan will tend to run more often so you may want to change it January first and again in Mid March.
If you have central air conditioning, then it’s a good idea to check the filter monthly in the summer to make sure it is clean. Changing every 2-3 months is usually sufficient.
It is more important to check and replace the filter than to pay extra for an expensive filter you only change once a year. Having a clean filter will extend the life of your furnace and can save you a significant amount of money by following a maintenance schedule.
Is your furnace not starting up and maybe making a funny sound like it is trying to start up? Perhaps you have shut it off and then turned back on. Maybe you just turned the fan on and it works. You may be in need of a new induced draft motor or draft inducer motor. This motor is what creates a draft through the heat exchanger. Air and gas are drawn through the front of the furnace and conveyed to the flue connector. What you have is a whole assembly. In most cases the entire assembly is what gets replaced. In some rare cases you can replace just the motor which is cheaper but takes longer to do. When replacing the assembly it is important to replace the gasket that goes between the assembly and the heat exchanger manifold. The gasket is usually fiberglass or fire rated foam. Modern furnaces have this motor as well the circulating or blower motor. Out of the 2 motors, the inducer motor typically is the one that fails first. The bearings start to wear out making the operation noisier and eventually they fail and the motor stops turning. I have seen motors with noisy bearings run for a long time (years) and in other cases no increased noise is noticed before the motor fails.
The induced draft assembly is typically made of steel or metals such as the one in the picture.
They often develop rust and wear out. Replacing the draft inducer motor assembly is the only way your furnace will operate.
How much should I expect to pay to replace my draft inducer motor assembly?
Depending on the make and model expect to pay between $500 and $800 for residential gas furnaces. At Tobin you can count on us to tell you what the problem is and give you a fair reasonable price ti install a new draft induced motor.

"Great Service. My furnace was short-cycleing and would shut off right after it turned on. They came really quickly, cleaned the parts and didn't charge me more then the service fee. They were very professional and nice. A really good family owned company. I would highly recommend."
- Brie Cook
"My furnace went out and I called up TOBIN to get an estimate. I had three other estimates for similar furnaces and the other companies wanted $1000 more. I hired TOBIN and had a high efficiency Amana furnace installed for much less than the other companies. I was very happy with the two service technicians who came out. They had to do some additional piping to vent the furnace and everything looked neat and clean when they were finished. I highly recommend the professionals at TOBIN."
