HVAC FAQ Customers might have Climatek

Question about AC

We know how it feels when your ac breaks on the hottest days of the year, it is best to call Climatek Heating and cooling service company in spring for ac tune-up to prevent service call, the most common problem is faulty capacitor or unit low on Freon, ac units that are older than 10-15 years.


It could have many other mechanical and electrical problems, one of those problems are bad compressors or weak compressors that need hard start capacitors Call us to properly diagnose and repair your ac unit.

We highly recommend having your ac cleaned and checked every year in spring, Ac systems with dirty coil and slightly low on Freon may still cool your house but it will run inefficiently and cause high electricity bills.

Call ClimaTek local heating and cooling company and we will clean and check your ac and make sure it's running efficiently and without breakdowns on those summer hot days.

If you see frozen pipe at the air conditioner or at the evaporator coil above the furnace then the probable cause could be low freon or airflow issue, if there is no ice then probably the condenser fan is running but the compressor is not. This type of diagnostic must be done by a professional HVAC technician,


Call ClimaTek heating and cooling and we will perform a diagnostic and repair on your ac unit.

Question about Furnace

There are many reasons why a furnace is not heating, some of most common problems are bad ignitor, dirty flame sensor, or dirty filter that causes the furnace to overheat.

To properly diagnose the problem with your furnace and safely perform repairs it is better to call your local heating service ClimaTek and we will guarantee repairs and give you peace of mind.

Most likely dirty flame sensor or furnace safety controls.


To keep your furnace working efficiently and safely it's highly recommended to have your furnace tune-up done beginning of the winter season

The most common noise is from the inducer fan motor that is failing due to the bad bearings in the motor.

Have your furnace inspected before the winter season, one of the many checks on our maintenance checklist is to check inducer fan motors for proper operation.

It's recommended to change fiberglass filters every 30 days, pleated filters 3-6 months but every filter should be inspected every 30 days and see if it's necessary to replace it, every house is different when it comes to dust.

Furnace cleaning and checks are very important to keep your furnace running safely and efficiently, we recommend furnace tune-up every year in fall before turning the heat on,

Call ClimaTek heating and cooling company, and we will inspect and clean your furnace and make sure there are no safety issues with the furnace, also by having a tune-up done there is a lower chance that your furnace will fail during the winter season.

Condensate pipe or trap plugged up


Have your furnace cleaned and checked and we will make sure all pipes are clear to prevent that service call.

Call ClimaTek your local heating and air conditioning service company.

With a multi-zone, radiant system probable case is an issue with zone valves, zone pumps, thermostats, or air in the radiators, with a single zone system most likely is air in the radiators.


Call ClimaTek Heating and Cooling for boiler maintenance, repair, or replacement installation.

Question for Air Quality

In the summer season when ac is running this is usually an indication of a frozen evaporator coil above the furnace due to airflow restriction from a dirty filter, blower motor not working, dirty evaporator coil or system is low on Freon. Check Climatek Air Quality Services

In the winter season when furnace heat is on probable cause is a bad blower motor, a dirty filter causing the furnace to short cycle due to furnace overheating.

Call (847) 322-0554 Climatek heating and air conditioning to perform a diagnostic on your furnace or ac.

Question for Humidifier

Humidifiers are very important to be checked every year preferably when your furnace is checked, probable causes of humidifiers leaking are overused water pad, water flow too high, or cracked feed tube.


Call ClimaTek to have your humidifier checked and cleaned, we will make sure it is working efficiently and have it running without leaks that could cause damage to your floor.

Question about Radiator

A boiler is not working, the circulating pump not working or air in the system.

Call ClimaTek and we will clean and check your boiler and make sure it's working safely and efficiently

I have recently experienced an AC issue where ClimaTek inc, at a time of notice, stopped by and within no time fixed the unit, as it was not blowing cool air. I would recommend ClimaTek Inc to anyone looking for HVAC services.

Cliamtek company was professional, responsive and fair from beginning to the end. I had 3 companies come out for a estimate I needed new furnace and ac replaced. Climatek gave me the best deal possible. Al came in the morning 9am and was done by 6pm with the work. Installed and cleaned up after himself. Very professional and knowledgeable guy. I will do all my Hvac needs with Climatek and Al. I recommend to anyone give him a try, also to mention ABC had a so called deal buy one get one, I don't think so there was nothing but 1 get 1 in the deal Al beat everyone by far with quality equipment too. Thank you Al

Climatek inc, provided great service over the years maintaining my hvac system. This year i have decided to replace the entire hvac system - including furnace, air conditioner, and new insulated duct work to be installed in the attic as my floor duct are corroding away causing in-proper air flow in some rooms. The current hvac system is ready for retirement. Climatek was honest and upfront all these years helping me get the most out of my old hvac system, and for that am grateful. i would recommend Climatek inc to anyone. They truly mean customer satisfaction guarantee. Thank you for all your support!

You saved a marriage!!! After dealing with almost 2 days of high humidity and temperatures with no AC and 2 very crabby people, I called Climatek on a Saturday and they were the only one who was able to come and fix the AC. He was honest and described the problems so I could understand them. I will continue to use Climatek! THANK YOU!

I have been using Climatek for five years now. They recently replaced my AC system in my home. The service was professional, friendly and they were on time. I highly recommend Climatek for their outstanding quality and service!

My older central air system developed a small leak and was not cooling - hot weather was forecasted for the next week. I thought I would try Climatek. Al exceeded my expectations, he quickly diagnosed the problem, put in some leak stop and charged the system. It was back up and running quickly. A week later a different problem surfaced where the compressor would not start, Al came up with a solution and had me back up and running in minutes. I highly recommend Climatek for their prompt knowledgeable service at a reasonable cost.

Bought a new thermostat and was having trouble installing it. Called around and everyone seemed to be charging wayyy too much to install it. Yes i get it that it was 9pm at night but it’s something I needed done that night in order to sleep with these hot nights we have been having. Called climatek and they gave me the best price in town to come install it at such short notice and it being late at night. Al was very helpful and a nice guy. Definitely will be calling him from now on to do all maintenance work and etc that needs to be done. Wouldn’t recommend anyone else around

These guys are amazing! They came out and got my air going quick. My wife is happy again and the home is at peace. 😉 Thank you so much Al
