"Brian is the owner-operator of the business and was right on time arriving at an easily scheduled time. He not only cleaned the dryer vent but also cleaned and disinfected all the furnace/air conditioning vents in our entire house. He did the work efficiently, kept us apprised of what things he was finding in the vents, was considerate of noise and hose & ladder hazards, and installed new filters in the return vents. I would highly recommend him to everyone who might need these services. As far as price & value, I found that his thoroughness and efficiency accompanied by his personable demeanor left me confident in his work and was well worth the price!"

"After a ghastly quote for repair from another outfit caused me to get a 2nd opinion, I'm so glad to have found ac medic on Home Advisor!!! Bob fixed our problem for less than 1/10 the cost of the other co.(which also turned out to have lied about the problem). I learned a lesson about "coupon" deals! Big markup on the part (although it did include labor), but service fee was waived since there was a repair involved. We'll definitely refer this co. to everyone!!!"

"Mark did a good job and went above and beyond in his efforts to diagnose and repair my air conditioning system. He also charged me less than 1/4th what parker and sons was going to charge me to do the same job. He acted very professionally and I would definitely recommend his services."

"Trusted does good work but their prices are very high. The original cost of this visit was approximately $400 and after we complained about the excessive cost, we were given a small discount. Our neighbor received an estimate for a new AC system and was quoted ~&7,000; however, a new Trane system was installed by Oasis for ~$3,000.
They do know what they are doing, but it they are very busy in the summer and they are expensive.

Air Conditioning questions, answered by experts

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
