"For 4 years we have been unable to get an HVAC specialist to come to our house to address an interior unit leak and those that did come prior could not figure it out. Frustrated, I reached out to Home Advisor and the next day CRS was at our home. They reviewed the situation, contacted the manufacturer and found that an original part had been discarded in installation which was likely causing the leak. A couple days after their first visit - our only first floor a/c was working beautifully (after its installation 6 years ago!). CRS was quick to address, innovative in approach, went the extra mile, professional, and reasonably priced. We couldn't be happier that CRS was able to help us with this longstanding problem."

"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"Customer service and communication was outstanding. The quick response to resolving our problem (hot water heater replacement) was greatly appreciated. Not sure if the 5-star â valueâ rating is appropriate since we didnâ t pursue competitive pricing...we didnâ t bother because they were exceptional on all other fronts."

Heating and Air Conditioning questions, answered by experts

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.
