"One Person’s Thoughts A career focused upon business strategy for global companies has taught me that there are two types of relatively successful (lifetime duration unknown) to successful (long-term over many years) companies; • Good companies • Great companies. Good companies focus upon sales and immediate revenue events. Immediate sales revenue is a singular event -- once the revenue is in the till future revenue requires significant renewed efforts and becomes much less predictable. Sustaining a company upon immediate revenue is a difficult, high energy, and high cost of customer access process. Great companies focus upon building brand through long-term customer partnerships. Building these customer partnerships requires expending much more effort and customer care up front, while micro-focusing upon building long-term sustainable revenue from families of parents, children, grandchildren and family relations. Great company customer partnerships also lead a to durable, sustainable brand image for companies; recognizing that brand image is not build by money and/or advertising, but by understanding and humanity on a customer by customer basis. Brand image is customer experiential and cannot be created through advertising, marketing or immediate sales. Building customer partnerships requires understanding and customer compassion through five phases of partnership: • Initial information and needs analysis • Marketing and sales • Customer care by actively and compassionately resolving all customer questions and concerns • Installation with open information sharing about timing, concerns, issues, and challenges • Customer follow up and care – touching the customer during and immediately after the install event and in an on-going manner at least three to four times a year after that. From my very recent experience, Road Runner a Good company, one with a way to go to become Great!"

"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!"

"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."

"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."

Heating and Air Conditioning FAQs, answered by experts

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.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

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.

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.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.
