Our pledge is to create successful relationships with our customers, employees and community by building trust, treating every project with the utmost integrity and exceeding expectations.
"From the moment I received a call from Tammy at Advanced Environment Solutions Inc. (AES), I knew I was dealing with a company that stands out from the rest. We had been shopping around for HVAC replacement quotes, and to our surprise, AES offered an over-the-phone estimate that was a staggering $7,000 less than any other quote we had received. This wasn't just a promise; it was a reality that they delivered on with professionalism and integrity. The process was seamless. After a quick confirmation visit by their technician to verify our unit size, everything was set in motion. On the day of installation, despite the sweltering heat, AES's teams worked with remarkable efficiency. One team expertly removed our old unit, and almost immediately, another arrived with the new one. The entire replacement was completed in a single day, leaving us both amazed and immensely grateful. The staff at AES were not only professional but also incredibly courteous and knowledgeable. They explained each step of the process, ensuring we understood everything. The quality of the new HVAC unit they installed surpasses any expectations we had, offering superior performance and energy efficiency. What's most puzzling and impressive is how AES manages to undercut competitors by such a significant margin while providing top-notch service and quality. This is a testament to their business model, which prioritizes customer satisfaction and ethical pricing. We highly recommend Advanced Environment Solutions Inc. to anyone in need of HVAC services. Their commitment to excellence, combined with unbeatable pricing, makes them the go-to choice. Contact AES, and like us, you'll discover why they are simply awesome!"

"Premium Home services is a scam..their customer sevice does not do anything about refunding back expensive, terrible and unfinished work. They hang up on you and give you the run around to speak with a so called manager. They send a so called professional to do the work, ask for a ridiculous amount of service call out fee and don't finish the job. The tech was unorganized and shows up hours late. Don't recommend the company."

Heat pumps rely on evaporation and condensation processes. The unit transfers heat through the system via a compressed refrigerant. The compressor within the pump circulates the refrigerant through two coils. The first coil evaporates the refrigerant and absorbs warmth from the air. The refrigerant then passes to the second coil, where it condenses, and the unit releases the absorbed heat.
A well-installed and well-maintained heat pump lasts an average of 12 to 20 years. Routine filter changes, annual tune‑ups, and prompt repairs help the equipment reach the upper end of that range, while skipped maintenance or poor installation can shorten its life and raise long‑term costs. Ask your heat pump installation pro for maintenance recommendations so you can get the maximum benefit from your unit.
Heat pumps are most effective in regions where winter lows remain above approximately 40°F. Efficiency starts to drop below that point and falls off sharply near 25°F. If you live in a colder area, look for a model with a high Heating Seasonal Performance Factor (HSPF) and plan on supplemental heat during deep freezes to keep energy use in check.
The biggest drawbacks are the upfront cost and poor cold-weather performance. Installation can require electrical upgrades or duct changes, and once temperatures fall well below freezing, the unit may need help from a furnace or electric resistance coils. Factor in those add‑ons, along with routine maintenance, when you weigh the long‑term savings against the initial investment.
