What Signs Indicate It Is Time for a Service Call?

There are specific signs and can happen with your central air conditioning unit that can only be repaired using a competent, licensed heating and cooling technician. Usually, if there have been no problems with the HVAC system, routine maintenance is usually all that is necessary to keep it operating efficiently. However, many of the troubleshooting signs that indicate it is time for a service call from a licensed technician include:

No Cool Air – On hot days when the A/C system will not produce cool air, it is usually an indication that it is low on refrigerant, or requires cleaning. With regular preventative air-conditioning maintenance, low refrigerant can be avoided.

Will Not Run – Sometimes the circuit breakers trip or fuses break and instantly stop the function of the A/C unit. However, this may be a sign of something drastically wrong with the HVAC system. Other times, the problem can simply be a broken thermostat. If the circuit breaker has been tripped, reset it. If the unit turns off again, it is time to consult with a licensed HVAC professional.

Hot Then Cold – Anytime the air-conditioning/heating system swings back and forth in temperature from hot to cold, there may be issues with the heat-pump cycle. Other causes might be a thermostat set in the wrong location, or improper thermostat calibration. Both the heat pump cycle problem and the improper calibration of the thermostat require the skills of a licensed professional to correct both concerns.

Loud Noises – Loud rumbling or scraping noises in the air handler, evaporator coils, condensing unit or compressor require the skills of a licensed HVAC professional to evaluate and repair the problem. Specific causes of the noise might be a result of damaged bearings in the blower, a loose belt, a compressor about to blow or other moving parts generating the sound. Sometimes the noise can be a result of expanding and contracting duct work that can be remedied by adding insulation around the ducts to abate the sound.

Performing the Repairs

Like any other mechanical device you use, there will be times when it is not functioning properly. Wear and tear, improper maintenance, and other scenarios can cause the HVAC system to not operate efficiently. In times like this, it is important to call on a license, service HVAC repairman to assess the problem and perform the repairs.

Frequent air conditioning repair problems often require routine maintenance on a semi-annual basis. Other more critical issues might require full replacement of the unit.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

Snyder Heating and AC is dependable, always on time and techs have always been courteous and knowledgeable. Emanuel was a great addition to the company. He was friendly and knew what he was doing. Thank you for great service.

Snyder came in and did a total overhaul of our duct system. They had a great knowledge of what to do to make our home so comfortable! The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

-Michele Bauer

Very prompt, professional, courteous, and cleaned up after repair. Had water line break in my front yard and no pressure. Very pleased and would highly recommend Snyder for all your plumbing, and AC needs. Thank you for making a rough morning get better with ease and professionalism.

-Chuck Jr.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation. He did a great job converting our old 3 knob shower to one. Looks great! Professional and courteous. 100% recommend this company, especially Clint.
