Mostly vacation homes, rentals, air b and b’s, move outs, etc. My team does a lot of cleaning for Century 21 among other realtors in our mountain area. We are reliable, have reasonable rates, pay attention to detail. And very prompt. You would not be disappointed with our service.

"Last week I had Landmark energy upgrades, do energy efficiency work at my home. The work included sealing all my duct-work in the attic as well as sealing all the spots between the living space below and blowing in additional insulation in order to bring me up to today's standards. I also had them replace all the duct work in my crawlspace and seal it as well as when they came for their initial inspection they found that my duct-work was riddled with holes and was completely uninsulated as well as being unsealed. I initially contacted Landmark after receiving notification that they were offering assorted rebates for home owners to incentivize them to do upgrades to there homes.
I was super pleased with these guys, a total of two crews worked on our home and they were both quick, professional, and explained what they would be doing in detail when they first arrived. They also did a good job cleaning up after themselves. Immediately I noticed a difference in my home after the work was finished. The HVAC system weren?t running nearly as much and the temperature in the home was absolutely more consistent.  Landmark Energy Upgrades promptly handled all the paperwork required in order for me to receive my rebates making this part of the process extremely easy. I fully recommend these guys!

Heating and Air Conditioning FAQs, answered by experts

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.
