We offer affordable prices and guaranteed workmanship. Contact us at 651-287-0379, so we can help you drive in comfort.

Why maintaining your AC System is very important:
Heating and A/C systems may break eventually with usage, hose pipes may clog and drip if not serviced, causing reduced efficiency heating and cooling capabilities. Regular maintenance will keep your AC system operating at peak performance!

Indications your A/C system may be having issues:

  • If your air conditioning blows only slightly cooler air compared to the exterior air
  • Air that blows in smells damp, musty, or like mildew and mold
  • Your cabin does not warm up in cold weather, or is just a little warmer than outside
  • The defroster takes longer than typical to operate, or does not operate
  • Your heater or A/C only functions when driving, not when idling, or quits blowing when the car is stationary
  • Your heating system blows cold air, or the air conditioning blows warm air
  • Low airflow even at the highest fan setting.

A comprehensive evaluation of heating and A/C system includes:

  • Examining the internal controls and blower
  • Checking radiator coolant operating temperature, hoses, pressure radiator cap and thermostat
  • Inspecting the compressor belt
  • Inspecting system and seals for leaks or various other damages.
  • A cooling system pressure test
  • Verifying the A/C pressure meets manufacturer specifications
  • Measuring the interior vent air temperature

Our repair and maintenance services include:

Air Conditioning
Have you been sweltering in your vehicle lately? Perhaps your car's air conditioner isn't functioning properly. At Dynotech Auto Repair we have qualified service professionals who can fix your air conditioner. To have an air conditioning system serviced, repaired, or replaced by experts consider visiting Dynotech Auto Repair. You can also call us at 651-287-0379 with any questions relating to your vehicle's air conditioner.

Coolant System Flush
A car's air conditioning system contains a coolant which transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the a/c coolant becomes old and dirty. The old coolant will negatively impact the system's performance. To make sure the system is working effectively, consider having a regular coolant system flush. A coolant flush is basic maintenance for your car's cooling system. Call 651-287-0379 or visit Dynotech Auto Repair in Saint Paul, MN 55104 for all your coolant system flush and fill needs. Ensure maximum performance from your vehicle's heating and cooling systems today.

Belts
A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belts will dry out and crack. When you are ready for a replacement you can count on Dynotech Auto Repair for all your vehicle's repair needs.

You not only have to get the belts replaced with quality ones but you should have the work done by experts. To have the belts replaced by auto cooling and heating experts - and get your car driving right - visit Dynotech Auto Repair today. The mechanics at Dynotech Auto Repair will thoroughly inspect your car's belts; replace all worn belts; and adjust the installed belts.

Hoses
Hoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Sooner or later, your vehicle's hoses will dry out and crack. When you are ready for a replacement you can count on Dynotech Auto Repair for all your vehicle's repair needs.

You not only have to get the hoses replaced with quality ones but you should have the work done by experts. To have the hoses replaced by auto cooling and heating experts - and get your car driving right - visit Dynotech Auto Repair today. The mechanics at Dynotech Auto Repair will thoroughly inspect your car's hoses; replace all worn hoses; and adjust the installed hoses.

Radiators
Radiators are heat exchangers for cooling your car's internal combustion engine. A radiator cools the engine by circulating an engine coolant through the engine block - it then loses the heat to the atmosphere through radiation. A radiator has a set of tubes through which the engine coolant flows. Fins surround these tubes. When the radiator fails, the excess heat produced by the engine could damage the engine components. To prevent this from happening, have your radiator serviced regularly. To have your radiator needs handled by experts, visit Dynotech Auto Repair today.

Radiator Flush
A radiator is the part of your vehicle that keeps the engine cool and protects it from excessive heating. To be cool, the radiator needs to remain clean - always. With time, sludge, rust and other solid deposits build up inside your car's radiator. These make the cooling system become clogged and less effective. This in effect hurts your vehicle's performance. A regular radiator flush is enough to keep the system in shape. For this reason, make radiator flushing a part of your routine car maintenance schedule. For all your radiator flush needs, call 651-287-0379 or visit Dynotech Auto Repair today.
