"I am very pleased with the service and equipment. Patrick was prompt, did the work quickly and cleaned up afterward. His price was very reasonable and he has called to check on the system and make sure I am satisfied. I know he will be there right away if I have any problems. I had no experience with choosing a system for an older house in Santa Fe. There is no ductwork. It was heated with a wood stove. The mini split system has given me three zones in the house where I can control the heat or cooling separately. This is perfect for me because I don't have to heat or cool areas that I am not using."

"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."

"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

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.
