"I called Roadrunner and they sent a technician out the same day. He identified the problem and gave me an estimate for the regulator repair and having a new water shutoff valve installed. I felt the cost of the regulator was high and he suggested that I could purchase the part myslef and only pay for installation charges. The part would not receive Roadrunners guarantee, however. I decided to locate and buy the needed parts and called Roadrunner for guidance. They were very helpful in guiding me to the correct parts. I called once I purchased the parts and they came out and installed them the next day. The technician was very professional and friendly. He completed the job in about 1.5 hours and cleaned up thoroughly afterwards. A month later, and everything is performing normally."

"The guy is wonderful, friendly, professional, and very reasonably priced. He cleaned my dryer vent which was completely blocked (by previous owners of my house) and he cleaned to evap cooler vents which were snowing mineral crystals all over my sofa (again previous owners left it in that condition). I feel so relieved now. Thanks!"

"I had an excellent experience with Tru Air. Lionel came out and answered all of my questions and gave me an estimate. Jesse and Oscar came out and removed my old units and installed a new Trane A/C, furnace, and coil. Chuy came out to inspect the system and get it up and running. I love this Trane, how quiet it runs and the 2 stage operation."

"Title: Exceptional, trustworthy plumbing — highly recommended Galactic Mechanical & Plumbing exceeded every expectation. After a frustrating runaround with other companies, Jordan drove up from Albuquerque to Santa Fe, waived the trip charge, and quickly diagnosed that I only needed a faucet fixture (not a full sink). He went to Home Depot, installed the new fixture, fixed a few other small issues, and left everything working — all billed fairly for one hour of labor. Jordan was professional, efficient, and honest; Megan in the office was courteous and helpful. As a longtime local with two homes, I’m already planning to use Galactic as my go-to plumber. Highly recommend them for reliable, respectful, and skilled service. Thank you, Jordan."

Heating and Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.
