How do I know I will get the right system installed in my home?

Hamstra Heating & Cooling provides Energy Star* quality installations. Our Comfort Specialists will sit down and talk to you about your needs to make sure we meet your heating and cooling expectations.

Energy Star* quality installations

  • Proper sizing of your new equipment Essential to getting the best performance and comfort. We perform a Manual J Load Calculation to determine the correct size system for your home.
  • Sealing ducts Evaluate your duct system to identify leaks, and then seal them using mastic, metal-backed tape, or an aerosol-based sealant.
  • Ensuring proper refrigerant charge An incorrect refrigerant level can lower efficiency by 5% to 20% and can ultimately cause premature component failure, resulting in costly repair.
  • Optimizing air flow Test air flow and make any needed adjustments for optimal performance.
Be sure to take each of these items into account when speaking with any company that you choose to provide you with a quote. No matter what type of system you purchase, improper system sizing and installation can reduce your systems efficiency by up to 30%. This will cost you more on your utility bills and possibly shorten the equipment’s life.

R22 Phase Out

R-22 is an HCFC refrigerant that is often used in air-conditioning equipment. To protect the Earth’s protective ozone layer, the United States is phasing out R-22, along with other chemicals.
  • As of January 1, 2020, the production but not the use of R-22 is being phased out. You are not required to stop using R-22 air conditioners nor to replace existing equipment.
  • R-22 supplies will be limited so costs to service equipment with R-22 may rise.

How will this affect servicing my current system?

  • You may continue to have your equipment containing R-22 serviced.
  • The most important thing you can do is to maintain your unit properly. Appropriate servicing minimizes potential environmental damage and maintenance costs.
  • If your older system needs a major repair, it’s likely in your best interest to look into system replacement options instead of spending thousands of dollars on a system that may be near the end of its expected service life.

How would I benefit from a new system?

  • Systems that use alternative refrigerants that do not harm the ozone layer are available and will become more common.
  • The most common alternative to R-22 is R-410A, a non-ozone-depleting HCFC refrigerant blend Repair costs would be less costly with the alternative refrigerant.
  • New energy efficient air conditioners save energy costs.
