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,
