"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."

"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."

"They had great communication with me and were very polite. They even gave me the cell number of the estimator to work out the details of a modified cost estimate. They were extremely fast and efficient in getting out to the Futura House and getting me a cost estimate as well as replacing the hot water heater. If you want work done fast and complete, this is the company you want to use."

Air Conditioning FAQs, answered by experts

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.
