Michelle was very professional. She checked my unit inside and my condenser unit outside. Made a recommendation to replace my capacitor on my condenser. She noted that it wasnt something that was imminent, but should be replaced before the hot summer takes full effect and puts additional strain on my system. I truly appreciated her honesty in her assessment and she didn't push me to have it repaired immediately. She explained the issue and gave me the estimate and told me to schedule it at my convenience. CTR is a great company with honest profrssionals. I will continue to use them for my HVAC services and recommend them for yours as well.Original Review:Called CTR to come and check my AC that was leaking water after seeing all their 5* reviews from previous customers. The secretary was very understsnding and put me on the schedule for same day. They did even better and responded within a couple hours of me calling. The tech contacted me when he was enroute told me the likely problem and the estimated price to repair. It was exactly what he said and the issue was fixed in no time! Thank you CTR for your prompt and professional response. Highly recommend them!

Seasonal Fall & Spring System Performance, Proper Functionality, & Safety Inspections Include:

  • Complete Inspection of the indoor and outdoor equipment
  • Inspect the electrical components/wires
  • Inspect cleanliness of indoor and outdoor equipment
  • Inspect blower wheel and motor
  • Inspect evaporator coil and drain pan
  • Inspect water overflow devices
  • Inspect drain lines

  • Inspect combustion air
  • Measure gas pressure
  • Replace air filter h/o supplied
  • Test for carbon monoxide levels
  • Test Smoke alarm
  • Professional clean condenser
  • Clear drain lines

One of the most important things we do? Take a few measurements! That is to say, these numbers tell our highly trained technicians a lot of information about your heating or cooling system’s efficiency and operation.

  • Log compressor amps
  • Read blower motor amps value
  • Measure outdoor temp / indoor WB temp
  • Test temperature differential
  • Measure refrigerant levels
  • Looks for signs of leakage & rust
  • Condenser fan amps
  • Check inducer motor amps
  • Log capacitor uF value
  • Check Static Pressure

COMFORT IN SAFETY

In addition to ensuring your system operates efficiently, we also have specific safety checks we conduct. As the heart of your home, it’s imperative we inspect your heating and air conditioning equipment for safety’s sake regularly.

  • Check CO and smoke detector
  • Inspect drain safety switch
  • Verify proper wire size to unit
  • Inspect all electrical connections
  • Test gas shut-off operation
  • Check circuit board for burn marks
  • And more!

FACTS AND STATS

Last but not least, we check your thermostat and air filters. It sounds simple, but a faulty stat or dirty filter can really affect your comfort and the efficiency of your HVAC system.

  • Is it operating correctly?
  • Does the programming need to be adjusted?
  • When was the last time the batteries were replaced?
  • Is it mounted firmly to the wall?
  • Do the air filters need to be changed?

HVAC Maintenance With No Hidden Fees!

What do you get when we’re finished (besides peace of mind)?

A copy of our HVAC maintenance checklist with notes (which tell you if items are “good” or “need attention”) as well as recommendations to improve the longevity, efficiency, and/or safety of your system. This is where you choose whether or not you want to move forward with any suggested repairs and upgrades, or if you were simply having your system checked and don’t want to mess with any additional work.

No fine print. No sales pitch. Just a thorough evaluation of your heating and cooling system and some recommendations if you’re interested in saving money, breathing cleaner air, or extending the life of your HVAC system.
