Repair & Service

Preventive Maintenance


Repair or Replace?

To repair or replace is the question that likely comes to mind whenever your heating or cooling system stops working. Although repairing may be the most affordable solution now, it might not be the best choice in the long run.

Rules of Thumb

Fifty percent rule: When the cost of repairs approaches 50% of the value of your heating or cooling system, it’s generally time to replace the system.

Age of unit or history of problems: Even if needed repair costs aren’t quite as daunting as 50%, you might want to replace your system if it’s more than 12 years old or you’ve had a history of problems with it. 

Rooms are too hot or too cold: Duct problems, inadequate air sealing or insulation could be the cause. If your home is not properly sealed or insulated against air leakage, your system will have to work extra hard.

Humidity problems and/or excessive dust: Poorly operating or improperly sized equipment could be to blame. Monthly maintenance of your equipment’s filters might help.

Your score on the ENERGY STAR Home Energy Yardstick is below five. If your score is below five you are using more energy than most people and are paying more than you need to on energy bills.

  • Convenience – avoid the hassle of unexpected repairs down the line, and no waiting for parts
  • Lower utility bills – high-efficiency home comfort system can save you hundreds of dollars each year in energy costs
  • Energy tax credits – recover up to 30% of the cost of select high-efficiency systems in the form of tax credits.
  • Eco-friendly refrigerant – due to growing environmental concerns, the U.S. federal government has mandated that all HVAC manufacturers phase R-22 refrigerant-based equipment out of production. Equipment manufacturers now only produce cooling systems with R-410A, a U.S. EPA-approved, chlorine-free refrigerant.
  • Enhanced comfort – enjoy more even temperatures, better humidity control and a constant flow of conditioned air.
  • Improved air quality – better humidity control means a less mold and mildew growth.
The technician was prompt, courteous, and efficient. He put on “floor savers” and covered the work area before quickly diagnosing the problem. Unfortunately the required part (inducer motor) had to be ordered and that meant waiting until the next morning. In the meanwhile, the tech suggested a suitable portable heater and even found where one could be purchased by doing a search on-line. He was back the next morning at 8:30 and completed the installation in minutes.

I was particularly pleased to learn that the technician had NOT installed a generic inducer motor but the one made for my furnace. The original motor lasted 14 years but its after-market replacement (put in by a different company’s repairman) had lasted LESS than two years. Of course that didn’t seem right and is the reason I called Four Winds this time. And, to top it off, Four Winds charged me $200 less!

Four Winds did a great job for us putting in a new furnace and AC this week, even though they hit a few minor bumps, they stayed professional and made it happen. Everyone was very helpful and accommodating so THANK YOU!!!!s always a good job seemed to be done. I also have to say I’ve done business with 4-Winds for a number of years and always satisfied. They seem to be 100% honest and hoping they stay that way.

Same day service was terrific. My repairman fixed the problem quickly and inexpensively — and showed me how to maintain the system to prevent the problem in the future. I would highly recommend!

We’ve been a customer for years and we have no complaints. Can’t say enough good about them.

Fast response time for an emergency air conditioner not working before the heatwave. AC was not the problem but tech gave suggestions on what the problem might be. Called my electrician and problem solved. Thank you so much.

As always, GOOD JOB! Technician did a good job with the furnace check-up a few months ago. A while later my carbon monoxide detector went off. I called them and tech was here in 20 minutes. All was fine! Been doing business with them for a while now and as long as they keep their honesty it’s all VERY good. Call them, they are honest and do good work.

Four Winds did a great job! I took the day off work because I thought my central air was going to take all day to repair and expected the repair to be expensive. To my surprise, my repair man was able to come early and was finished before 11am. I did not have to waste my day waiting around for the repair man to run and get parts, he was prepared and had the part I needed with him. I was able to accomplish so much on my day off because they were so fast. Everyone was very friendly and the best part is that it cost a lot less than I expected.
