We offer affordable prices and guaranteed workmanship. Contact us at 520-351-2061, 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 Covenant Automotive Repair & Service 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 Covenant Automotive Repair & Service. You can also call us at 520-351-2061 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 520-351-2061 or visit Covenant Automotive Repair & Service in Tucson, AZ 85712 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 Covenant Automotive Repair & Service 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 Covenant Automotive Repair & Service today. The mechanics at Covenant Automotive Repair & Service 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 Covenant Automotive Repair & Service 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 Covenant Automotive Repair & Service today. The mechanics at Covenant Automotive Repair & Service 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 Covenant Automotive Repair & Service 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 520-351-2061 or visit Covenant Automotive Repair & Service today.

Testimonials

  • We found our former auto repair shop closed only to "randomly" pull into Mark Knaak's, Covenant Automotive, LLC today. While it makes sense to get an appointment, they performed mechanical service on two of our cars without hesitation. They were pleasant to work with, asked appropriate questions, provided information and excellent service second to none. Mark is a VERY experienced mechanic and able to work on almost ANY make or model. He specializes in "high end" luxury vehicles. Raise your prices, Mark! You deserve EVERY penny. THANK YOU. We'll be back!
    -Thomas & Gloria W.

  • Mark was honest, kind, worked very efficiently, and made my experience at Covenant Automotive not only enjoyable but heaven sent. I will certainly be taking my Nissan to him and his team as long as they are in business in Tucson. Thank you Mark for your kind heart and excellent service!
    -Hallah K.

  • Very impressed! I just dropped in before 3pm on 2/19/2018 with my 2001 F150 Lariat, thinking I might need a fuel filter replacement..."Service Engine Soon" light was lit. When they checked, it was determined the truck was misfiring on #8. I thought I'd have to arrange another day to bring it in for the estimated 3 hour job; Mark assured me that he could get two guys to work on it right away, and if they had to go a little past 5, they'd do whatever was needed to get me going. Well, a whole set of plugs and a new coil, and they finished at 4:50! Amazing work!
    -Pam D.

  • My stepdad brings in our cars to Mark and he does a fabulous job taking care of them! I took my Nissan Maxima in for an oil change and to get my splash guard nailed back into place. They took excellent care of my car and I am very impressed with them! Will be back with my husband's car for an oil change, and will keep coming back! The oil change is a great price for the service that you receive!
    -Renee F.

  • Very honest work done in timely manner prices very good
    -Sean H.

  • Mark has worked on my Mercedes E350...and now a doge journey (only an oil change and inspection before cross country trip.) The service and above all, honesty you'll get here is just the best. We're moving east and will miss them!
    -Phyllis G.

  • Very honest and fair! My stepdad has been bringing the cars here for years and they are very fast and effeciant. I will be coming back again in the future for any work that needs to be done to my car.
    -Renee

  • Covenant has repaired my BMW multiple times and are amazing to work with. I always get a fair price and they are extremely responsive. They will continue to get my families business.

  • My 2000 GMC 1500 SLT 2WD with 147K original miles had developed a popping sound in the frt left side while I was visiting in Tucson, and being a bit of a motorhead from years past, I had a good idea as to what it was. I took it into a well known national chain garage to do an inspection, not only did they charge me $20 to do the inspection, they quoted me well over $2300 to complete the work. Then I did a little web search and found Covenant Automotive which is backed by NAPA so I called made an appt. I took it in as scheduled and they got right on it, doing the inspection and working up a quote, that is when Mark told me that he would quote the job in the most economical manner, which meant replacing the entire upper arm rather than replacing the bushings and the ball joint separately on both sides, as well as the tie rods on both sides. He quoted me $1017 and change which also included an alignment. They took me back to the RV Park where I was staying and finish! ed the work as promised, on time and on budget! I have driven the truck now for a few weeks, took a 500 mile road trip and I am completely satisfied with the quality level of their work. Mark and his team are not just mechanics, they are motorheads themselves and it is in their blood, they will work on your car or truck as if it was their own and they take great pride in their commitment to their customers My thanks to the team at Covenant Automotive, and Happy New Year!
    -Marc G.

  • All I can say is I wish you were here in Amarillo where I just moved. I've never had such good service from anyone, and I am a real skeptic when it comes to mechanics. You and your crew are the best. Thank you!
